Background technology

In extensive Hardware Design, the method for concurrent transaction level analog simulation is an important technological means.Concurrent transaction level simulation has that analog rate is fast, simulation scale large, modeling pattern presses close to the advantages such as hardware logic, can be applied to each stage such as the prototype assessment of hardware system, the software tuning of hardware system.

Due in existing paralleling transaction level modeling method, mainly set up partial model, by partial model and the simulation of annexation each other concurrent transaction level simulation system thereof.Partial model and each other connect and compose concurrent transaction level simulation system, therefore should consider communication between partial model with miscellaneous part model when design part model or be connected, how to simulate the communication connection of concurrent transaction level simulation system, also will consider the logic function of partial model.Conventional partial model comprises processor model, memory model, router-modelle etc.For the existing processor model realizing additional calculation, processor model should realize the communication connection with outside miscellaneous part model, need to obtain all data of carrying out add operation from outside, also to carry out the additional calculation of data, finally also will by the result feedback of calculating to miscellaneous part model.In view of the foregoing, when design part model, not only need the logic function being concerned about this partial model also will be concerned about the miscellaneous part model with this processor with annexation, also will consider whether its annexation can meet the requirement of the communication connection of concurrent transaction level simulation system.

Accordingly, during design concurrent transaction level simulation system, need the logic function considering partial model, also will consider whether its annexation meets the requirement of the communication connection of self.Because both couplings are higher, when causing design concurrent transaction level simulation system and partial model, be easy to produce the design problem checked and balance.In addition, annexation and the logic function of current partial model mix, and a partial model can only be used in a concurrent transaction level simulation system, and reusability is poor, causes the wasting of resources of partial model comparatively serious.

On the one hand, the modeling person of component-level model needs the design being concerned about concurrent transaction level simulation system, and the modeling person of concurrent transaction level simulation system also needs the inside being concerned about component-level model to realize on the other hand.Because the degree of coupling of partial model and concurrent transaction level simulation system is higher, therefore both cannot complete independently design or amendment.This easily causes the development efficiency of concurrent transaction level simulation system lower, and larger to the expense of partial model and concurrent transaction level simulation system maintenance.

DATE ' 10 Proceedings of the Conferenceon the Design held in Europe of 2010, Automation and Test meeting is delivered one section to be called: the paper of " Parallel simulationof SystemC TLM 2.0 compliant MPSoC on SMP workstations ", author: Aline Mello, Isaac Maia, Alain Greiner, and Francois Pecheux.The article disclose a kind of analog platform of concurrent transaction level, this platform is specifically designed to the polycaryon processor of simulation shared drive, this platform also provides a kind of programming mode being called TLM-DT for this specific simulation application, obtains certain Parallel Simulation speed-up ratio.But the autgmentability of the method is not proven, and the method does not consider how decoupling zero partial model and concurrent transaction level simulation system, does not provide powerful support for for the reusability of partial model provides.

How to reduce the degree of coupling between partial model and concurrent transaction level simulation system, improve the development efficiency of concurrent transaction level simulation system, reduce the expense that partial model and concurrent transaction level simulation system are safeguarded, become one of current problem demanding prompt solution.

Partial model is generally transmitting terminal or the receiving terminal of message, and therefore partial model also can be described as communication source or communication objective end.For convenience of description, if indicate without special, in following content, communication source or communication objective end is namely represented with partial model.

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

As shown in Figure 1, the annexation of the port of the whole partial models comprised in a concurrent transaction level simulation system is represented.Comprise the annexation of the port of several partial models in this topological structure description document, each partial model comprises two parts content, and one is module information M1, and two is channel information M2.In module information M1, comprise the title of partial model, mark, type and number of active lanes, type is generally finger processor, internal memory, hard disk etc., and number of active lanes is the number of the communication port between this partial model and miscellaneous part model.In channel information M2, itemize have recorded the information of each port, the port information of a port recorded in every bar record, comprise the mark of the partial model having annexation with this port, title, have annexation with that port of this partial model, the title of this port, type, time of delay.Channel type generally comprises transmission types, type of receipt and transmission and to hold concurrently type of receipt.Refer to that this port sends a message and how long needs time of delay.

Such as, 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 miscellaneous part model.The module information of partial model A comprises, and the name of partial model is called A, is designated ID130, type is processor and number of active lanes is 4.Channel information comprises 4 records, the information of a port recorded in every bar record, if port a is in order to initiate a message, have communication connection with the port f of partial model B (being designated ID230), then the record of port a comprises: the mark ID130 of source, destination be designated ID230, the port name of source is called a, the port name of destination is called f, and channel type is transmission types, and time of delay is 0.04s.

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

According to the annexation between each partial model of concurrent transaction level simulation system to be simulated, annexation in described topological structure description document between analog component model, after partial model obtains described topological structure description document, according to content wherein, set up the annexation between partial model, then achieve the modeling of concurrent transaction level simulation system.

Described source is the issuing side of message, and the port of described source is in order to send described message; Described destination is the receiving terminal of described message, and the port of described destination is in order to receive described message.Because the transmission of message moves in circles with reception, the source of therefore message transmission, also can be the destination of message sink, in other words, source and destination can change according to the flow direction of message next time.In concurrent transaction level simulation system, partial model normally communicates source or communication objective end.

Described communication source is source to be established a communications link, the partial model namely in concurrent transaction level simulation system.After partial model has designed, set up the communication connection between partial model, the more parallel host network of configuration, concurrent transaction level simulation system just completes.For preventing in the process established a communications link, occurring situation about missing, the partial model designed, when establishing a communications link, regard this partial model as source to be established a communications link.

The port of described communication objective end is the port of the destination corresponding with the port of source described to be established a communications link, and described communication objective end is the destination corresponding with source to be established a communications link.Message is flowed by port in the entire system, when establishing a communications link, need to determine the communication source of message and communication objective end, guarantee that both are corresponding, then determine which port of communication source is corresponding with which port of communication objective end, ensure that message flows in the port of correspondence.

Be that described communication source and communication objective end set up communication port and after configuration communication passage based on described communication port information, communicate in the communication port set up for communication source and corresponding communication port information the port of source, the port of the communication port set up for communication objective end and corresponding communication objective end.Message is sent to communication objective end by the communication communication port of source, the communication port of configuration, and the communication port of communication objective end receives the message (will be described in detail follow-up to the parsing of message) after resolving.

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