Because in existing parallel transaction-level modeling method; That gives partial model reusablely provides enough supports; Cause the modeling person of component-level model need be concerned about the design of system-level model; The modeling person of system-level model also need be concerned about the inside realization of component-level model on the other hand, so the degree of coupling of partial model and parallel transaction-level analogue system is higher, and both designs and modification can't independently be accomplished.This will cause the development efficiency of parallel transaction-level analogue system lower, and to its safeguard and the expense revised also bigger.

Fig. 1 is a flow chart of setting up a kind of execution mode of the analogy method of communicating by letter between partial model provided by the invention, comprising:

S11 distributes said partial model with matrix form, confirm the dimension of said matrix;

S12 according to the type of said partial model, is divided into submatrix with said matrix, based on the dimension and the position generation distribution and expression formula of said submatrix in said matrix of said matrix;

S13 generates annexation based on position coordinates and the annexation between partial model to be simulated of said partial model in said matrix and expresses formula;

S14 checks whether the logic of said distribution and expression formula and annexation expression formula is correct;

S15 expresses formula based on said distribution and expression formula and annexation, generates the description document of parallel transaction-level analogue system.

Fig. 2 is the flow chart that distribution and expression formula provided by the invention and annexation are expressed a kind of execution mode of formula logical check, comprising:

S31 checks whether said annexation expression formula comprises the annexation of each partial model;

S32 checks whether said annexation expression formula comprises the annexation of the redundancy of said partial model;

S33 checks whether position coordinates is corresponding one by one with partial model in the said distribution and expression formula.

Specify the said analogy method of communicating by letter between partial model of setting up below in conjunction with Fig. 1 and Fig. 2.At first referring to Fig. 1:

Among the S11, said partial model being distributed with matrix form, generally be that the form of said partial model with two-dimensional grid, two-dimentional looped network or three-dimensional grid distributed, and the partial model of same type is placed on the zone of closing on more.For two-dimensional matrix, the dimension of said matrix comprises the line number and the columns of matrix.

Among the S12,, said matrix is divided into submatrix, is meant that generally the partial model with same type is divided in the sub-matrices according to the type of said partial model.The position of said submatrix in said matrix generally is meant which row and column in the corresponding original matrix of row and column that said submatrix comprises.For example, after being divided into submatrix, first of submatrix is listed as the 3rd row in the corresponding original matrix.

Partial model distributes with matrix form, and its position coordinates in matrix is represented its abscissa and ordinate respectively with matrix column and row, and position coordinates is the sign of this partial model.

Among the S13, represent this partial model, generate annexation based on position coordinates and the annexation between partial model to be simulated of said partial model in said matrix and express formula with position coordinates.For example, the position coordinates of partial model A does<x _l, y _p>, the position coordinates of partial model B does<x _v, y _u>, if having annexation between the two, its annexation is expressed formula and can be write as

Among the S13, all correct if said distribution and expression formula and annexation are expressed the logic of formula, then generate the description document among the S14.The logically true position coordinates of said partial model that is meant of said distribution and expression formula is corresponding one by one with partial model; Said annexation is expressed the logically true of formula and is meant the annexation that comprises each partial model in the said annexation expression formula, and said partial model does not have redundant annexation.

Referring to Fig. 2; Wherein among the S31; Check whether said annexation expression formula comprises that the annexation of each partial model is meant, said annexation expression formula comprises the annexation of each partial model, that is to say; Whether the situation whether inspection occurs missing has the annexation of certain partial model not to be included in the said annexation expression formula.In parallel transaction-level analogue system, there is not isolated partial model, that is to say to have an annexation between partial model and the miscellaneous part model at least.Among the S31, comprise the inspection that whether has isolated partial model, isolated partial model occurs and belong to logic error.In addition, if partial model A has three annexations, but only comprised two annexations in the said annexation expression formula, this also belongs to situation about missing, and also belongs to logic error.

Check whether said annexation expression formula comprises that the annexation of the redundancy of said partial model is meant; Check whether said partial model has unnecessary annexation, for example, partial model A has annexation with partial model B; But through annexation being expressed the logical check of formula; Having obtained that annexation has occurred twice between these two partial models, once is redundant obviously in this twice, belongs to logic error.

Check whether position coordinates is corresponding one by one with partial model in the said distribution and expression formula; Be meant that a position coordinates can only a unique corresponding partial model; And a partial model also has only a unique position coordinates corresponding with it, and position coordinates is the sign of partial model.If the corresponding a plurality of partial models of a position coordinates occur, perhaps a partial model has a plurality of position coordinateses and all belongs to logic error.

In above-mentioned logical check, any one or a few logic error appears, and then said distribution and expression formula or annexation are expressed the logic mistake of formula, can't generate description document.

Among the S14, all correct if said distribution and expression formula and annexation are expressed the logic of formula, then generate description document.Said description document comprises the position coordinates and the annexation of said partial model, and said annexation is with the Name & Location coordinate of source end pieces model, the Name & Location coordinate representation of destination partial model.Because position coordinates and partial model are one to one, therefore said position coordinates can be used as the sign of said partial model.

The matrix that said partial model forms is divided into submatrix according to type, therefore also comprises the type of said partial model in the said description document.The type of said partial model is except comprising: processor type, type of memory, the router type, can also comprise type of hardware, external memory type, switch type etc.

The said analogy method of communicating by letter between partial model of setting up, also be included in inspection said distribution and expression formula and annexation express the logic of formula whether correct before, check whether said distribution and expression formula and annexation expression formula meets preset grammatical information; Said syntactic information comprises the spelling requirement and the algorithm of said distribution formula and annexation formula.

Also comprise,, then feed back error message if said distribution and expression formula and annexation expression formula do not meet in said syntactic information, the logic error one or more.Said error message comprises: reason of makeing mistakes and the position of makeing mistakes are concrete:

Said reason of makeing mistakes comprises: said distribution and expression formula or annexation express formula misspelling, do not meet in the said algorithm one or more, said position of makeing mistakes comprises: the position of misspelling or do not meet the position of said algorithm.For example, the title misspelling of partial model, parameter title misspelling, multiplying is write as add operation etc.

Said reason of makeing mistakes also comprises: if said annexation expression formula lacks in the corresponding a plurality of partial models of the position coordinates of partial model in the annexation of said partial model, the annexation that comprises the redundancy of said partial model, the said distribution and expression formula and the corresponding a plurality of position coordinates of partial model one or more.Feeding back said information of makeing mistakes comprises: title, the feedback of the partial model of the said annexation of feedback disappearance have the title of the partial model of redundant annexation.If corresponding a plurality of partial models of position coordinates in the said distribution and expression formula, the information that feedback is made mistakes comprises: feed back the title of the corresponding a plurality of partial models of this position coordinates, feedback has the title of the partial model of a plurality of position coordinateses.

Said matrix generally is two-dimensional grid, two-dimentional looped network and/or three-dimensional grid.The distribution formula of two-dimensional grid, two-dimentional looped network and/or three-dimensional grid and the expression mode of annexation formula have certain similitude; These formula are represented with the form of formula system; Be created as the reference representation storehouse, can directly apply mechanically formula so in use.

Said reference representation storehouse comprises parameter distributions formula to be determined and annexation formula; During use based on the dimension and the position of said submatrix in said matrix of said matrix; Parameter in the distribution formula of confirming to set up in advance obtains said distribution and expression formula; Parameter in the annexation formula of confirming to set up in advance based on the position coordinates of said partial model in said matrix, said submatrix position and the annexation between partial model to be simulated in said matrix obtains said annexation and expresses formula.

Said distribution formula is:

The distribution formula of two-dimensional matrix is:

<x _g，y _h>，x _g＝a·i+b，y _h＝c·j+d，i＝[0，A-1]，j＝[0，B-1]，a∈N，b∈N，c∈N，d∈N，g∈N，h∈N

Said annexation formula is:

i∈[0，N]，j∈[0，N]，

n∈N，l∈N，p∈N，v∈N，u∈N

The target of parallel transaction-level modeling is exactly farthest to realize separating of partial model and parallel transaction-level analogue system, both design processes of de or modeling process.During the partial model modeling, need not to be concerned about the structure of parallel transaction-level analogue system; And during parallel transaction-level analogue system modeling, can directly utilize the existing parts model, set up the annexation between partial model through structure description file.

In parallel transaction-level modeling, if partial model is carried out appropriate design, can be so that it has reusable characteristic; Briefly; Be exactly the information that this partial model does not comprise system-level model, externally it seems to be exactly a receiving inputted signal, return " flight data recorder " of output signal.Based on this " flight data recorder ", the connection that the process of system-level modeling just only needs to describe these " flight data recorders " gets final product.

Fig. 3 is the matrix structure diagram intention of the distribution mode of partial model provided by the invention, specifies below in conjunction with Fig. 1, Fig. 2 and Fig. 3.

Shown in Figure 3 is the initial matrix of one 5 * 5 two-dimensional grid, and two base part model: sample_m1 and sample_m2 are wherein arranged, and sample_m1 representes processor, and sample_m2 representes internal memory.Type according to partial model is different, can this initial matrix be divided into a few sub-matrices pieces: N1, N2 and N3.Wherein N1 forms one 3 * 3 matrix, and matrix-block N2 forms one 2 * 3 matrix, and matrix N 3 forms one 5 * 2 matrix respectively.

The reference representation storehouse of setting up in advance comprises:

The distribution formula of two-dimensional matrix is:

The annexation formula of the partial model that two-dimensional matrix distributes is:

i∈[0，N]，j∈[0，N]，

n∈N，l∈N，p∈N，v∈N，u∈N

The syntactic information of above-mentioned two formula comprises:

Algorithm comprises:

1, at first by ltr and dig constructed variable (var), the rule (beginning of letter, any a plurality of letters of followed or digit) according to var can construct two variable a1, a2.

2, by dig structure numeral (num),, can construct numeral 10 according to the rule (digit beginning, any a plurality of digits of followed) of Num.

3, by the definition of formula (fom) (between numeral, variable or the numerical variable according to oper combination), can obtain formula: a1+a2-10.

Three sub-matrices as shown in Figure 3: N1, N2 and N3 are that example specifies with submatrix N1, for describing conveniently, abscissa in the position coordinates and ordinate be not there to be < x, y>expression of footnote here.

Because submatrix N1 is 3 * 3, in the upper left corner of initial matrix, the triplex row and three row of the corresponding initial matrix of data of triplex row that comprises and three row.Abscissa x can get three values between 0 to 2, and is same, and ordinate y can get three values between 0 to 2, and three kinds of values of the three kinds of values of x and y can combination in any, forms all positions in 3 * 3 matrixes.Therefore, the distribution and expression formula of submatrix N1 can be written as:

<x，y>，x＝i，y＝j，i＝[0，2]，j＝[0，2]。

The dimension 2 * 3 of submatrix N2 in like manner, in the lower left corner of initial matrix, preceding two row of corresponding initial matrix fourth line and fifth line.The distribution and expression formula of submatrix N2 is:

<u，v>，u＝i，v＝j，i＝[0，2]，j＝[3，4]。

The dimension 5 * 2 of submatrix N3, on the right side of initial matrix, the five-element's of corresponding initial matrix back two row.The distribution and expression formula of submatrix N3 is:

<m，n>，m＝i，n＝j，i＝[3，4]，j＝[0，4]。

(position coordinates is respectively (2,0), (2,1) to be positioned at tertial three partial models with submatrix N1; (2,2)), with submatrix N3 be positioned at the 4th row three partial models (position coordinates is respectively (3,0); (3,1), (3,2)) between annexation be that example explanation annexation is expressed formula.

If among the submatrix N1 the 3rd row first with submatrix N3 in first be listed as first and have annexation; Among the submatrix N1 among second of the 3rd row and the submatrix N3 second of first row have annexation, among the submatrix N1 the 3rd be listed as the 3rd with submatrix N3 in first be listed as the 3rd and have annexation.Submatrix N1 is in the left side of initial matrix, and the 3rd row of submatrix N1 are the 3rd row of initial matrix, and submatrix N3 is on the right side of initial matrix, and first row of submatrix N3 are the 4th row of initial matrix.Its annexation expression formula is:

R (< u, v >, < m, n >) = (\{\begin{matrix} u = 2 \\ v = i \end{matrix}, \{\begin{matrix} m = 3 \\ n = i \end{matrix}, i = [0,2])

In the said connection formula, the span of v and n is consistent, therefore can represent with identical parameter i.

In the said annexation expression formula, the part of numeral " 2 " and numeral " 3 " is to represent with predetermined syntactic information.For example, dig::=0|3|, num::=dig ^*, num representes numeral " 3 ", DIG::=0|2|, NUM::=DIG so ^*, NUM representes numeral " 2 ", so above-mentioned annexation expression formula becomes:

R (< u, v >, < m, n >) = (\{\begin{matrix} u = NUM \\ v = i \end{matrix}, \{\begin{matrix} m = num \\ n = i \end{matrix}, i = [0,2])

Wherein, NUM and num are the parameter according to the numeric type of preset grammatical information definition.

According to preset grammatical information, inspection distribution and expression formula and annexation express whether the grammer of formula is correct, and comprising: whether the spelling of parameter title is correct, and whether algorithm is correct.For example: num is made up of one or multidigit dig, and dig is Arabic numerals, and as 3 being correct num, because it is made up of a dig, and 3b is illegal num, because it is not made up of dig entirely, then can feed back following error message:

Error：Line：6，3b?is?wrong.

The num spelling of representing the 6th row makes mistakes.

Inspection distribution and expression formula and annexation are expressed the logic of formula, comprising:

Check whether said annexation expression formula comprises the annexation of each partial model;

Check whether said annexation expression formula comprises the annexation of the redundancy of said partial model;

Check whether position coordinates is corresponding one by one with partial model in the said distribution and expression formula.

For example, in the annexation expression formula that the annexation of partial model A does not comprise, then can feed back following error message:

Erro：model?A?is?miss。

Expression has lacked the annexation of partial model A.

If it is correct and logically true that said distribution and expression formula and annexation are expressed the syntactic information of formula, then generate description document.Said description document comprises the position coordinates and the annexation of said partial model, and said annexation is with the Name & Location coordinate of source end pieces model, the Name & Location coordinate representation of destination partial model.Said position coordinates and partial model are one to one, and therefore said position coordinates is the sign of said partial model, with said position coordinates representative and its corresponding components model.

Annexation between partial model A and the partial model B can show with the form of text description, for example, and [partial model A: the sign < 2 of source end pieces model; 1 >, partial model B: the sign of destination partial model < 3,1 >], have annexation between this expression partial model A and the partial model B; A is the title of source end pieces model, and it is designated < 2,1 >; B is the title of destination partial model, and it is designated < 3,1 >; Also can be with program code, the performance of forms such as graphic symbol, for example, code form: (modleA < 2 for R; 1 >, modleB < 3,1 >), R representes to have annexation between partial model modleA and the partial model modleB; ModleA is the title of source end pieces model, and its position coordinates (sign) is < 2,1 >; ModleB is the title of destination partial model, and its position coordinates (sign) is < 3,1 >.

Annexation between the partial model can be classified, and generally has two kinds: unidirectional connection and two-way annexation.For example, be unidirectional annexation between partial model A and the partial model B, expression partial model A is to unidirectional transmission message of partial model B or event content, and perhaps partial model B is to unidirectional transmission message of partial model A or event content; Be two-way annexation between partial model A and the partial model B, expression partial model A sends message or event content to partial model B, and partial model B also sends message or event content to partial model A.

The number of the annexation between the partial model and the type of annexation also can add in the said description document.For example, be two-way annexation between R (modleA < 2,1 >, modleB < 3,1 >) expression modleA and the modleB, S (modleA < 2,1 >, modleB < 3,1 >) expression modleA is to the unidirectional annexation of modleB.R (modleA < 2,1 >, modleB < 3,1 >), (modleA < 2 for R; 1 >, modleC < 4,1 >), R (modleA < 2,1 >; ModleD < 5,1 >), expression modleA has two-way annexation respectively with modleB, modleC, modleD respectively, and modleA has 3 annexations.ModleA has two-way annexation respectively with modleB, modleC, modleD respectively, and modleA has 3 annexations and also can be kept in the description document.

Because different parallel transaction-level model implementation method is different, the design is the method for expressing of limiting part model not.Said description document is applicable to the parallel transaction-level modeling method of various systems and partial model loose coupling.The description document that generates can the time to the system model of physical simulation device code is described, also can be texts such as txt, word.

Fig. 4 is the flow chart of a kind of execution mode of the method for routing of communicating by letter between partial model provided by the invention, comprising:

S21, the description document of the parallel transaction-level analogue system of generation;

S22, the title of obtaining communication source end, said communication sources end is a source end pieces model to be established a communications link;

S23, the title of in the description document of said parallel transaction-level analogue system, searching the communication objective end corresponding with said communication sources end, said communication objective end is the destination partial model corresponding with source end to be established a communications link;

S24, the record communication port information, said COM1 information comprises the Name & Location coordinate of said communication sources end, the Name & Location coordinate of communication objective end;

S25 is that said communication sources end and communication objective end are set up COM1 and configuration communication passage based on said COM1 information.

In the modeling or design process of the parallel transaction-level analogue system of reality, the structure of partial model is very complicated, and said partial model comprises communication module, also comprises component logic, in order to realize logic function.

Said communication module comprises port router (also claiming router), communication controler and port queue administration module etc., and the port queue administration module is generally used for setting up COM1 according to COM1 information.The port router comprises the routing iinformation administration module, and said routing iinformation administration module comprises routing table cache module, enquiry module etc.COM1 comprises port arrangement module, message transmission module, message processing module etc.

The port queue administration module obtains the port number of these parts model from enquiry module, and obtains the COM1 information of each port successively.Annexation between partial model generally has three kinds: COM1 generally can be divided into three types: only send message COM1, receive only the COM1 of message or event content, not only sent but also received the COM1 of message or event content.The type of COM1 and number are generally speaking by the type and the decision of the annexation of this partial model.For example, partial model A and partial model B, partial model C, partial model D have two-way annexation respectively, and partial model A has three COM1s so, and this COM1 is for not only sending but also receive the COM1 of message or event content.If partial model A is to the unidirectional transmission message of partial model B, then partial model A has a COM1 that only sends message, and partial model B has a COM1 that receives only message or event content.

A COM1 has a COM1 information, that is to say, the number of COM1 information is consistent with the number of COM1.The port queue administration module obtains will in communication module, to create a new COM1 after the new COM1 information of each bar, with numeral or this COM1 of letter designation, and the corresponding communication port information is inserted the port information administration module.

The type of the annexation of partial model, number generally also can be included in the description document, and the title of COM1 generally is defaulted as numeral or letter in addition, when generating description document, can automatic ranked package be contained in the description document.

Fig. 5 to Figure 18 is the detailed applications method of the description document that provides in the embodiment of the invention; Said description document is also referred to as the topological structure description document; In the present embodiment, the communication module of partial model is set up COM1 according to COM1 information, correspondingly; Also comprise the port information (like title, sign etc.) of partial model in the description document, COM1 information also comprises the port information of communication sources end and the port information of communication objective end.Specify below in conjunction with Fig. 5 to Figure 18.

Fig. 5 is the structure list of the topological structure description document that provides of the embodiment of the invention, and the structure of topological structure description document is as shown in Figure 5.The topological structure description document is main unit with partial model, has described the essential information of each partial model, and the annexation of the port of this partial model.In order to avoid a conflict, the topological structure description document requires being designated of partial model overall unique, and the title of the port of partial model is unique in this partial model.Because being designated of partial model is overall unique, the title of port only need guarantee in the partial model unique, and this port is carried out just can not making a mistake when topological structure is described.

Partial model is generally the transmitting terminal or the receiving terminal of message, so partial model can be used as communication sources end or communication objective end.For describing conveniently, if no special indicating promptly represented communication sources end or communication objective end with partial model in the following content.

What this topological structure description document was described is the annexation between partial model, and has specifically noted annexation between the port of port and miscellaneous part model of a partial model.

As shown in Figure 5, the annexation of the port of whole partial models of representing to comprise in the parallel transaction-level analogue system.Comprise the annexation of the port of several partial models in this topological structure description document, each partial model comprises two parts content, and the one, module information M1, the 2nd, channel information M2.Among the module information M1, comprise title, sign, type and the number of active lanes of partial model, type generally is finger processor, internal memory, hard disk etc., and number of active lanes is the number of the communication port between this partial model and the miscellaneous part model.Itemize has write down the information of each port among the channel information M2; The port information of a port of every record record; Comprise sign, title that the partial model of annexation is arranged with this port, annexation is arranged, the title of this port, type, time of delay with which port of this partial model.The title of port generally is defaulted as Arabic numerals or letter, and according to numeral or alphabetical rank order.Port type generally comprises transmission types, type of receipt and the transmission type of receipt of holding concurrently.Be meant that this port sends a message and how long needs time of delay.

For example, partial model A has 4 ports, and the title of 4 ports is respectively a, b, c, d, and has 4 communication ports between partial model A and the miscellaneous part model.The module information of partial model A comprises, the name of partial model is called A, is designated < 2,1 >, type is processor and number of active lanes is 4.Channel information comprises 4 records, and the information of a port of every record record is if port a in order to initiate a message, (is designated < 3 with partial model B; 1>port f) has communication and connects, and then the record of port a comprises: the sign of source end < 2,1 >; Being designated of destination < 3,1 >, the port name of source end is called a; The port name of destination is called f, and channel type is a transmission types, and be 0.04s time of delay.

The general communication according to parallel transaction-level analogue system to be simulated of topological structure description document connects, and sets up the annexation of source end and destination.When establishing a connection, the type of the port of said source end is a transmission types, and then the type of the port of the destination corresponding with it can only be for type of receipt or receive the transmission types of holding concurrently, and same partial model both can be that the source end also can be a destination.

According to the annexation between each partial model of parallel transaction-level analogue system to be simulated; Annexation in said topological structure description document between the analog component model; After partial model obtains said topological structure description document; According to content wherein, set up the annexation between the partial model, then realized the modeling of parallel transaction-level analogue system.

Fig. 6 is a kind of flow chart of execution mode of the method for routing of COM1 provided by the invention, comprising:

S101 obtains the topological structure description document, and said topological structure description document comprises the title of port of title and destination of port of sign, the source end of sign, the destination of source end;

S102, the title of the port of obtaining communication source end, said communication sources end is a source end to be established a communications link, the port of said communication sources end is the port of source end to be established a communications link;

S103, title and the sign of communication objective end of in said topological structure description document, searching the port of the communication objective end corresponding with the port of said communication sources end;

S104, the record communication port information, said COM1 information comprises the sign of said communication sources end, the title of the port of communication sources end, the sign of communication objective end, the title of the port of communication objective end;

S105 is that said communication sources end and communication objective end are set up COM1 and configuration communication passage based on said COM1 information.

The analogy method that the topological structure description document of step S101 can utilize shown in Figure 1 setting up to communicate by letter between partial model generates, and said source end is the partial model that end initiates a message in other words conj.or perhaps that sends of message, and the port of said source end is in order to send said message; Said destination is the partial model that the receiving terminal of said message receives message in other words conj.or perhaps, and the port of said destination is in order to receive said message, and promptly source end and destination have annexation.Because the transmission of message moves in circles with reception, thus the source end of message transmission, also can be the destination of message sink next time, in other words, source end and destination can change according to the flow direction of message.In parallel transaction-level analogue system, partial model is communication sources end or communication objective end normally.

Said communication sources end is a source end to be established a communications link, the partial model in the just parallel transaction-level analogue system.After the partial model design was accomplished, the communication of setting up between the partial model connected, and disposed parallel host network again, and parallel transaction-level analogue system is just calculated completion.For preventing that in the process that establishes a communications link the situation that occurs missing designs the partial model of accomplishing, and when establishing a communications link, regards this partial model as source end to be established a communications link.

The port of said communication objective end is the port of the destination corresponding with the port of source end said to be established a communications link, and said communication objective end is the destination corresponding with source end to be established a communications link.Message flows through port in whole system; When establishing a communications link; Need to confirm the communication sources end and the communication objective end of message; Guarantee that both are corresponding, confirm that then which port of communication sources end is corresponding with which port of communication objective end, guarantee that message flows in corresponding port.

Based on said COM1 information is after said communication sources end and communication objective end are set up COM1 and configuration communication passage; The COM1 of setting up for the communication sources end is the port of communication sources end in the corresponding COM1 information, and the COM1 of setting up for communication objective end is the port of corresponding communication objective end.Message sends to communication objective end through the COM1 of communication sources end, the communication port of configuration, and the COM1 of communication objective end receives the message (parsing to message will be elaborated follow-up) after resolving.

Generally speaking, the port of transmission types is corresponding with the port of type of receipt or the double transmission types of reception; The port of type of receipt is corresponding with the port of transmission types or the double transmission types of reception; Send the port of the type of receipt of holding concurrently, if send message, then the port with transmission types is identical, if receive message, then the port with type of receipt is identical.

The module information and the channel information that comprise this partial model in the topological structure description document; Wherein module information comprises title, sign, type and the number of active lanes of this partial model, and number of active lanes is the number of the communication port between this partial model and the miscellaneous part model.Itemize has write down the information of each port in the channel information, comprises sign, title that the partial model of annexation is arranged with this port, annexation is arranged, the title of this port, type, time of delay with which port of this partial model.

Among the S104, the record communication port information can selectively be noted these information according to actual conditions, and generally COM1 information only writes down the information of port commonly used, like this can conserve storage.

Said communication port is used for transmitting message, and communication port is generally realized through parallel host network.

Figure 11 is the structure chart of a kind of execution mode of parallel transaction-level analogue system provided by the invention, and parallel transaction-level analogue system A6 comprises partial model A62 and parallel host network A 61.

Each partial model A62 simulates the part among the parallel transaction-level analogue system A6 independently, and carries out the transmission of message through parallel host network A 61.When carrying out between the partial model A62 when mutual, will transmit message through parallel host network A 61.When simulation walks abreast transaction-level analogue system A6, realize comprising event content or incident bag in the message alternately through message between two partial model A62.The incident bag is the packet of User Defined structure.In this packet, the user is with being the event content of granularity with the sequential between the abstract realization hardware module.

The interaction protocol that the process of interacting message is common and partial model A62 adopts is irrelevant; Usually do not relate to concrete details such as bus timing; That is to say that component logic A4 sends or receive result, communication module A3 is responsible for becoming message to send through its COM1 A2 the incident collation package.Component logic A4 is indifferent to message and by whom is sent, and only is concerned about and has sent what message, has received what result.Accordingly, communication module A3 is indifferent to and sends or received what message, only is concerned about whose transmission whom to send to.This has been divided into two parts with partial model A62, and component logic A4 is responsible for sending the incident bag or receives result, and communication module A3 is responsible for sending or receiving message.During design part model A62; Which kind of communication no longer is entangled with in parallel transaction-level analogue system needs connect; How annexation between the partial model designs; When design walked abreast the transaction-level analogue system, how the annexation of also no longer being entangled with between partial model designed the communication connection that could satisfy parallel transaction-level analogue system.These annexations or communication connection are preset in the topological structure description document; Only need obtain this document; Communicate the configuration of passage according to the content of this document, just can satisfy the demand that the communication of parallel transaction-level analogue system connects, and also realize the annexation between the partial model.

This not only reduces the degree of coupling between partial model and the parallel transaction-level analogue system, and improves the development efficiency of parallel transaction-level analogue system.If when the annexation between the partial model or the changing of communication link sending and receiving of parallel transaction-level analogue system; Only need to revise content corresponding in the topological structure description document; Then route cache table and COM1 information are upgraded, just can be accomplished the modification that the communication of annexation or parallel transaction-level analogue system between the partial model connects.The expense that this reduces partial model and the maintenance of parallel transaction-level analogue system no longer needs design part model or parallel transaction-level analogue system again, has strengthened the reusability of partial model, reduces the wasting of resources, has practiced thrift cost.

Figure 16 is that the communication of partial model in the parallel transaction-level analogue system provided by the invention connects sketch map.Figure 12 is described in the correspondence between the partial model A62 of two parallel runnings in the parallel transaction-level analogue system, has omitted and other structures here.The structure of the communication module A3 of parallel transaction-level simulation and the applied environment in parallel transaction-level analogue system thereof are shown in figure 16, and communication module A3 mainly comprises: COM1 A2, communication controler A31, port queue modules A 32, port router-A 1.Port router-A 1 obtains outside topological structure description document.

COM1 A2 is connected with port router-A 1 through port queue modules A 32, can obtain the information in the port router-A 1 through port queue modules A 32.

Shown in figure 16, carry out through communication module A3 alternately between two partial models, when component logic A4 need carry out PERCOM peripheral communication, will at first pass to communication module A3 to the incident bag, be responsible for incident sealed by communication module A3 and dress up message and transmit; Equally, when receiving message, the message of receiving will at first be responsible for processing by communication module A3, passes to component logic A4 again.Under this design; Component logic A4 carries out with the outside communication module A3 that will rely on fully alternately; Can under the situation of not considering external condition, realize the internal logic of partial model A62 independently, this design has improved the development efficiency of partial model effectively.

Each partial model A62 can be divided into two parts, and a part is not relate to externally mutual component logic A4, and another part is the communication module A3 that is responsible for outside mutual.Figure 16 is the structure chart of a kind of execution mode of incident bag provided by the invention, and Figure 17 is the structure chart of a kind of execution mode of message provided by the invention.

Incident bag B1 shown in Figure 17 comprises the title B11 and the event content B10 of transmit port, and the title B11 of transmit port is the title of the port of communication sources end just.Incident bag B1 is sent by component logic A4.Message B2 shown in Figure 18 comprises event content B10, the sign B12 of communication sources end, the title B11 ' of the port of communication sources end, the sign B13 of communication objective end, the title B14 of the port of communication objective end.Wherein the title B11 ' of the port of communication sources end is identical with the title B11 of transmit port among Figure 17.Message B2 is after receiving incident bag B1 by communication module A3, adds that ingress port information forms, and is finally sent by COM1.

In sum, the disclosed technical scheme of the embodiment of the invention, the development efficiency of the parallel transaction-level analogue system of raising reduces the expense to partial model and the maintenance of parallel transaction-level analogue system.

Though the present invention with preferred embodiment openly as above; But it is not to be used for limiting the present invention; Any those skilled in the art are not breaking away from the spirit and scope of the present invention; Can utilize the method and the technology contents of above-mentioned announcement that technical scheme of the present invention is made possible change and modification, therefore, every content that does not break away from technical scheme of the present invention; To any simple modification, equivalent variations and modification that above embodiment did, all belong to the protection range of technical scheme of the present invention according to technical spirit of the present invention.
