Example 1

Fig. 1 is a flow chart of a method for updating a port signal in a system-on-chip integration according to an embodiment of the present invention, where the method is applicable to a case of adding a port signal in a system-on-chip integration, and the method may be performed by an apparatus for updating a port signal in a system-on-chip integration, and the apparatus may be implemented in a form of hardware and/or software, and may be configured in an electronic device. As shown in fig. 1, the method for updating port signals in the system on chip integration provided in the first embodiment specifically includes the following steps:

S110, when the on-chip system is determined to need to update the port signal, acquiring original hierarchical relation information of the unit to be replaced in an original grammar structure corresponding to the on-chip system.

The application scenario of this embodiment can be understood as follows: in the integration of a system on chip, many co-provider IP blocks need to be integrated. In the integration process, because the IP module is a general module, in order to adapt to the integration of the system on chip, some standard units in the IP module are replaced by own standard units, and when the standard units are replaced by own standard units, the ports of the standard units to be replaced are inconsistent with the original ports of the standard units in the IP module, and a plurality of signals can be more than the original ports, so that the port signals of the bottom layer need to be modified.

The grammar structure corresponding to the IP module provided by each cooperation provider is recorded as an original grammar structure.

In this embodiment, it is generally described in a user manual which standard units need to be replaced in the IP module integration process, so as to replace the standard units with the standard units, for example, the standard units need to be replaced for the basic units. If the port signal is required to be updated, the method provided by the embodiment needs to be utilized to add the port signal into the grammar structure.

The unit to be replaced can be understood as an IP module that needs to be replaced in the integrated process of the system on chip. And the IP modules are in signal transmission through ports. In order to perform port signal addition, when it is determined that the system-on-chip needs to perform port signal update, the original hierarchical relationship information of the unit to be replaced needs to be acquired first. The original hierarchical relationship information may be understood to include information such as the hierarchy in which the unit to be replaced is located in the entire syntax structure, which hierarchy is above this hierarchy, the order in which the hierarchies are arranged, and the like. It should be noted that, while determining the original hierarchical relationship information of the unit to be replaced in the original syntax structure corresponding to the system on chip, it is also necessary to determine the signal direction of the port signal added by the unit to be replaced. Wherein the signal direction may be input or output. The signal bit width of the port signal to be added may be single bit or multiple bits.

For example, assuming that the unit to be replaced is an add unit, the obtaining the original hierarchical relationship information to be exchanged is: top.u1.u2.u3.u4.u5.u6.u7.u8.u_name.u_add, add units are on level 11, where Top, u1, u2, u3, u4, u5, u6, u7, u8, u_name are respectively the upper levels of the levels where add units are located.

S120, adding port signals to be added of the units to be replaced into the original hierarchical relationship information to obtain target hierarchical relationship information.

The port signal to be added of the unit to be replaced is recorded as the port signal to be added. In this embodiment, after the original hierarchical relationship information is obtained, the level where the unit to be replaced is located is known. Adding the port signal to be added into the original hierarchy relation information, namely adding the signal name of the port to be changed on the hierarchy to be replaced and the port to be changed, and adding the signal name of the hierarchy located at the higher hierarchy until reaching the highest hierarchy. And recording the hierarchical relation information added with the port signals as target hierarchical relation information.

Continuing to describe the above example, when it is determined that the add unit is on the 11 th hierarchy, the hierarchical relationship is top.u1.u2.u3.u4.u5.u6.u7.u8.u_name.u_add, a signal name of the port signal to be added is added on the add, and the port signal name of the connected last hierarchy is added, so that the determination of the signal flow direction can be realized through the added signal name. Specifically, the hierarchical signal names above u_name remain unchanged until the top layer is reached, and after port signals are added, the hierarchical relationship is as follows:

Top (d) (d) u1 (d) (d) u2 (d) (d) u3 (d) (d) u4 (d) (d) u5 (d) (d) u6 (d) (d) u7 (d) (d) u8 (d) (d) u_name (d) (d) u_add (I) (d), wherein the contents in the first bracket of each hierarchy represent the signal names of its own ports and the contents in the second bracket represent the signal names of the ports of the last connected hierarchy. The names of the signals of the ports of each hierarchy may be the same or different, and the link relationship may be maintained. That is, in the above example, the names of the above hierarchical signals are each named d, or the names of the above hierarchical signals may be respectively named as different names, and the unevenness may be named as d.

S130, calling a preset through signal script, and carrying out signal updating processing on the system on chip by combining the target level relation information.

Specifically, after the target hierarchical relationship information is obtained, the register conversion stage circuit (Register Transfer Level, RTL) engineering is subjected to signal passing processing according to the target hierarchical relationship information, namely, the system on chip is subjected to signal updating processing. In the present embodiment, the number of ports to be added is not particularly limited, and may be one or a plurality of ports, for example. The signal bit width of the port signal to be added may be single bit or multiple bits. For each unit to be replaced and each new signal in each unit to be replaced, the signal script and the target level relation information corresponding to the new signal can be utilized to update the new signal.

The preset signal threading script can be understood as a pre-generated script which can be used for executing signal threading, and batch signal threading operation can be executed by using the signal threading script instead of manual operation. The process of performing signal update processing by using the through-signal script in combination with the target hierarchical relationship information can be described as follows: taking a target level in the target level relation information as a current level through a signal passing script; reading the current signal name of the port signal of the current level and the previous signal name of the port signal of the previous level connected with the current level from the target level relation information through the signal passing script; adding the current signal name into the current level of the original grammar structure through a signal penetrating script; acquiring a previous level connected with the current level according to the name of the previous signal through a signal penetrating script; the last level is used as the current level through the signal passing script, and the step of continuously executing the current signal name of the port signal of the current level and the last signal name of the port signal of the last level connected with the current level through the signal passing script is returned; until the level included in the target level relation information is traversed, the signal updating process is completed.

In the present embodiment, it can be considered that the execution of the method is based on a script file. And the script file performs signal updating processing on the system on chip according to the target hierarchical relationship. It can be known that in the prior art, when a certain signal of a certain unit is added, signal declarations need to be performed on each layer involved, and the level is not complex for penetrating signals with fewer levels, but when the level is deeper and standard units to be replaced are many, the processing is very complicated and errors are easy to occur; the script tool batch processing is very suitable for the complicated problems, and the processing efficiency is improved.

The embodiment of the invention provides a method for updating port signals in system-on-chip integration, which comprises the following steps: firstly, when the on-chip system is determined to need to update port signals, acquiring original hierarchical relation information of a unit to be replaced in an original grammar structure corresponding to the on-chip system; then adding port signals to be added of the units to be replaced into the original hierarchical relationship information to obtain target hierarchical relationship information; and finally, calling a preset through signal script, and carrying out signal updating processing on the system on chip by combining the target level relation information. Compared with the prior art, the signal declaration operation process of each level is very complicated; according to the technical scheme, the hierarchical relation information of the unit to be replaced is obtained, the port signals to be added are added to the hierarchical relation information, and the signal updating processing is performed by using the hierarchical relation information after the signals are added, so that the updating processing process of the port signals is simplified, the processing efficiency is improved, and the processing cost is reduced.

As an optional embodiment of the embodiments of the present invention, on the basis of the foregoing embodiment, the method may be optimized further includes: and when the first signal quantity of the port signals of the replacement unit is more than the second signal quantity of the port signals of the unit to be replaced in the integrated module in the integrated process of the system on chip, determining that the system on chip needs to update the port signals.

In the integrated process of the system on chip, a replacement unit of the system on chip needs to replace a unit to be replaced in an IP module, the number of port signals of the replacement unit is recorded as a first signal number, and the number of port signals of the unit to be replaced is recorded as a second signal number. In this alternative embodiment, it is necessary to determine in advance whether the port signal update is required, and when the first signal number is greater than the second signal number, it is determined that the port signal update is required.

The above technical solution adds the step of updating the port signal.

Example two

Fig. 2 is a flow chart of another method for updating port signals in a system-on-chip integration provided by the second embodiment of the present invention, where the present embodiment is a further optimization of the above embodiment, in the present embodiment, the optimization is further defined for "obtaining the original hierarchical relationship information of the unit to be replaced in the original syntax structure", and the optimization is further defined for "adding the port signals to be added of the unit to be replaced to the original hierarchical relationship information, obtaining the target hierarchical relationship information", and further defined for "calling a preset through signal script, and performing signal updating processing on the system-on-chip by combining the target hierarchical relationship information".

As shown in fig. 2, the second embodiment provides a method for updating port signals in system-on-chip integration, which specifically includes the following steps:

and S210, when the on-chip system is determined to need to update the port signal, adding a printing function to the unit to be replaced and compiling codes to obtain the original hierarchical relation information of the unit to be replaced in the original grammar structure.

Specifically, when it is determined that the on-chip system needs to update the port signal, a print function (i.e., print function) is added to the unit to be replaced, and codes are compiled to print out the hierarchical relationships of all the units to be replaced, and the hierarchical relationships are recorded as the original hierarchical relationship information of the unit to be replaced. The hierarchical relation information comprises a target hierarchy where the unit to be replaced is located. In this embodiment, the level at which the unit to be replaced is located is referred to as a target level.

S220, extracting a target level where the unit to be replaced is located in the original level relation information.

For example, assuming that the unit to be replaced is an add unit, the obtaining the original hierarchical relationship information to be exchanged is: top.u1.u2.u3.u4.u5.u6.u7.u8.u_name.u_add, add units are on level 11.

S230, adding the signal name of the port signal to be added to the target level.

Specifically, the signal name of the port signal to be added is added to the target level, wherein not only the signal name of the port signal to be added, but also the signal name of the port signal of the level connected with the port needs to be added.

Further, adding the signal name of the port signal to be added to the target hierarchy includes:

a1 A signal name of the port signal to be added is taken as first added content.

Specifically, the signal name of the port signal to be added is recorded as the first added content, and it is assumed that the port signal l is added at the level where the add is located by way of example.

b1 The signal name of the last port signal of the last hierarchy of the target hierarchy connection is taken as second added content.

Specifically, the signal name of the last port signal of the last hierarchy connected to the target hierarchy is used as the second added content. Illustratively, let d be the last port signal of the last level of the level where add is located.

c1 The first added content and the second added content are added to the target hierarchy in the set order.

The setting order may be that a first bracket places the first added content and a second bracket places the second added content. Illustratively, the port signal name d of the add itself and the port signal l of the connected upper layer are added in the set order, to obtain u_add (l) (d).

S240, adding connection relation information of each upper level to each upper level of the target level to obtain the target level relation information.

In this embodiment, the level above the target level is designated as the upper level, and in order to realize the purpose of penetrating the added port signal to the topmost level, it is necessary to add connection relationship information of each upper level to each level, and obtain final target level relationship information.

Further, adding connection relation information of each upper hierarchy to each upper hierarchy of the target hierarchy to obtain target hierarchy relation information, including:

a2 For each upper hierarchy, the signal name of the port signal of the upper hierarchy is taken as the third added content.

Specifically, for each upper hierarchy, the signal name of the port signal of the upper hierarchy is noted as the third added content. Illustratively, the content in the first bracket in each hierarchy described below is the third added content.

Top(d)(d).u1(d)(d).u2(d)(d).u3(d)(d).u4(d)(d).u5(d)(d).u6(d)(d).u7(d)(d).u8(d)(d).u_name(d)(d)。

b2 A signal name of a last port signal of a last hierarchy connected to the last hierarchy is used as fourth added content.

Specifically, the signal name of the last port signal of the last hierarchy connected to the last hierarchy is referred to as fourth added content. Illustratively, the content in the second brackets in each hierarchy described below is the fourth added content.

c2 The third added content and the fourth added content are used as connection relation information of each level, and each connection relation is added to the upper level in a set order.

The setting order may be that the first bracket places the third added content, the second bracket places the fourth added content. Illustratively, the target hierarchical relationship information may be expressed as:

s250, calling and using the target hierarchy in the target hierarchy relation information as the current hierarchy through the signal passing script.

Specifically, a through-signal script is called, a target level where a unit to be replaced is located in the target level relation information is obtained through the through-signal script, and the target level is used as a current level.

S260, reading the current signal name of the port signal of the current level and the previous signal name of the port signal of the previous level connected with the current level from the target level relation information through the signal passing script.

Specifically, each level in the target level relationship information includes the signal name of the present level and the signal name of the previous level. Based on the through signal script, reading the signal name of the port signal of the current level and marking the signal name of the port signal of the previous level connected with the current level as the previous signal name.

S270, adding the current signal name into the current level of the original grammar structure through the signal passing script.

The step can be understood as a step of adding signals, and in the embodiment, the manual operation is performed based on the through-signal script agent, so that batch processing can be performed by utilizing script mechanization, and the complexity and error of the manual operation are avoided.

S280, acquiring a previous level of current level connection according to the name of the previous signal through the signal passing script.

Specifically, through the signal passing script, according to the name of the last signal, the last level of the current level connection can be determined.

S290, returning to the step S260 by taking the previous hierarchy as the current hierarchy through the signal passing script.

S2110 is performed until the hierarchy included in the target hierarchy relationship information is traversed, so as to complete the signal update processing.

When each level information in the target level relation information is traversed, the signal updating process is realized, which is equivalent to that each level in the original grammar structure is subjected to signal increasing.

The technical scheme includes the steps of obtaining original hierarchical relation information of a unit to be replaced in the original grammar structure, adding port signals to be added of the unit to be replaced to the original hierarchical relation information to obtain target hierarchical relation information, calling a preset penetrating signal script, and carrying out signal updating processing on the system on chip by combining the target hierarchical relation information. By acquiring the hierarchical relation information of the unit to be replaced, adding the port signal to be added to the hierarchical relation information, and performing signal updating processing by using the hierarchical relation information after adding the signal, the updating processing process of the port signal is simplified, the processing efficiency is improved, and the processing cost is reduced.

In order to more clearly describe the method for updating the port signal in the system-on-chip integration provided by the embodiment of the invention, the method for updating the port signal in the system-on-chip integration is described by taking a certain practical application scene as an example. Fig. 3 is a flowchart illustrating an implementation of a method for updating a port signal in a system on chip integration in an application scenario according to a second embodiment of the present invention, where, as shown in fig. 3, the implementation steps of the method for updating a port signal in a system on chip integration specifically include:

And S2, when the on-chip system is determined to need to update the port signal, adding a printing function to the unit to be replaced and compiling codes to obtain the original hierarchical relation information of the unit to be replaced in the original grammar structure.
