[0033] Embodiment 1

[0034] Figure 1 This is a flow chart of a method for determining the direction of a bidirectional port provided according to the first embodiment of the present invention. This embodiment is applicable to the case of determining the direction of a bidirectional port in each module in a circuit diagram of an RTL design. The method can be executed by a device for determining the direction of a bidirectional port. The device for determining the direction of a bidirectional port can be implemented in the form of hardware and / or software. The device for determining the direction of a bidirectional port can be configured in an electronic device such as a computer, a server or a tablet computer. Figure 1 As shown, the method includes:

[0035] Step 110: Obtain a target circuit diagram designed by RTL, and determine the bottom-level modules of the target circuit diagram.

[0036] The target circuit diagram includes a plurality of modules, and each of the modules includes at least one bidirectional port.

[0037] It should be noted that in this embodiment, the target circuit diagram is not a traditional hardware connection circuit diagram, but is designed by RTL, which is at a higher level of abstraction and mainly focuses on how data is transmitted between registers and how these operations are coordinated through control signals. At this level, designers usually use hardware description languages ​​(such as Verilog or VHDL) to describe the behavior of the system, rather than the specific design of logic gates.

[0038] The bidirectional port involved in this embodiment can be an inout type port, which can be used to receive data and output data; it can be understood that for a module, the inout port can be used as both input and output, and the other module connected to the inout port should also be an inout port. The inout port cannot exist independently.

[0039] That is to say, when the inout port of one module is used as output, the inout port of another module must be used as input; conversely, when the inout port of one module is used as input, the inout port of another module must be used as output. Therefore, the control signals of these two inout ports are actually controlled by a pair of signals. Therefore, in the RTL module with multiple inout ports, the existence of inout will make the design analysis very complicated.

[0040] Optionally, in this embodiment, after obtaining the target circuit diagram designed by RTL, the target circuit diagram can be further analyzed to obtain each module of the target circuit diagram. Furthermore, the underlying modules of the target circuit diagram can be determined based on the positional relationship or connection relationship of each module.

[0041] It should be noted that, in this embodiment, the lowest module in the target circuit diagram is referred to as a bottom module, which may also be referred to as other modules, such as a first module or a second module, etc., which is not limited in this embodiment.

[0042] For example, Figure 2 is a schematic diagram of the structure of a target circuit diagram of an RTL design provided according to the first embodiment of the present invention, such as Figure 2 As shown, the target circuit diagram includes two modules (add and Top; add is the bottom module); and four bidirectional ports, namely add_a, add_b, top_a and top_b.

[0043] Step 120: When it is determined that the bottom-level module is a basic circuit element, determine that the direction of the first bidirectional port of the bottom-level module is an output direction.

[0044] Optionally, in this embodiment, after determining the underlying module of the target circuit diagram, it is necessary to further determine whether the underlying module is a basic circuit element; wherein the basic circuit element may include: a basic logic gate, a storage element, a buffer or a tri-state gate.

[0045] In an optional implementation of the present embodiment, after determining the underlying module of the target circuit diagram, it is possible to further determine whether the underlying module is a basic circuit element such as a basic logic gate, a storage element, a buffer or a tri-state gate; if so, the underlying module is determined to be a basic circuit element; otherwise, the underlying module is determined to be a non-basic circuit element.

[0046] Optionally, in this embodiment, when the underlying module is determined to be a basic circuit element, that is, the underlying module is composed of basic circuit elements such as basic logic gates, storage elements, buffers or tri-state gates, the direction of the first bidirectional port of the module can be further determined as the output direction.

[0047] In this embodiment, the first bidirectional port may be any inout port of the bottom layer module, which is not limited in this embodiment.

[0048] In another optional implementation of this embodiment, when it is determined that the bottom-level module is a non-basic circuit element, the direction of the first bidirectional port of the bottom-level module is determined to be an input direction.

[0049] It can be understood that in this embodiment, if the underlying module is determined to be a basic circuit element, then the direction of the bidirectional port of the underlying module can be determined to be the output direction; if the underlying module is determined to be a non-basic circuit element, then the direction of the bidirectional port of the underlying module can be determined to be the input direction.

[0050] Step 130: Determine each port connection line associated with the second bidirectional port of the upper layer module connected to the bottom layer module, and determine the direction of each port connection line.

[0051] In this embodiment, the upper layer module connected to the bottom layer module is the upper layer module directly connected to the bottom layer module, for example, Figure 2 The upper module of the bottom module add shown is the Top module; if the target circuit diagram contains three modules, then the upper module of the bottom module is the middle module of the target circuit diagram; that is, in this embodiment, the upper module does not refer to a single module in the target circuit diagram, but refers to the module in the target circuit diagram that is directly connected to the bottom module.

[0052] Optionally, in this embodiment, after determining the upper module connected to the bottom module, each second bidirectional port in the upper module and the connection between the second bidirectional port and the first bidirectional port can be further determined, which is referred to as a port connection in this embodiment. Further, the direction of the port connection can be determined; illustratively, Figure 2 The port connections involved can be light blue top_a and top_b.

[0053] In an optional implementation of the present embodiment, the direction of the port line connected to the first bidirectional port can be determined based on the port direction of the first bidirectional port; illustratively, when it is determined that the port line does not contain other driving sources, if the direction of the first bidirectional port is the output direction, then the direction of the port line connected to it is also the output direction; if the direction of the first bidirectional port is the input direction, then the direction of the port line connected to it is also the input direction.

[0054] In another optional implementation of the present embodiment, when it is determined that the port connection includes other driving sources, the direction of the port connection is not only related to the direction of the first bidirectional port, but also related to the specific driving mode of the driving source. In the present embodiment, the situation where the port connection includes other driving sources is not specifically described, and it is not a limitation of the present embodiment.

[0055] Step 140: Determine the direction of the second bidirectional port based on the direction of the first bidirectional port and the directions of the connection lines of each port.

[0056] The direction of each bidirectional port is either input or output.

[0057] Optionally, in this embodiment, after determining the direction of the first bidirectional port and the directions of the port lines connected to the first bidirectional port, the direction of the second bidirectional port may be further determined based on the directions of the first bidirectional ports and the port lines.

[0058] For example, in Figure 2 In the example, if the direction of add_a is output and the direction of port connection top_a is output, then the direction of top_a is also output; if the direction of add_b is input and the direction of port connection top_b is input, then the direction of top_b is also input.

[0059] The technical solution of this embodiment is to obtain a target circuit diagram designed by RTL and determine the underlying module of the target circuit diagram; wherein the target circuit diagram includes multiple modules, each of which includes at least one bidirectional port; when the underlying module is determined to be a basic circuit element, determine the direction of the first bidirectional port of the underlying module as the output direction; determine each port connection associated with the second bidirectional port of the upper module connected to the underlying module, and determine the direction of each port connection; based on the direction of the first bidirectional port and the direction of each port connection, determine the direction of the second bidirectional port; wherein the direction of each bidirectional port is: input direction or output direction, so as to quickly and accurately determine the direction of each bidirectional port in the RTL design, which can facilitate the design of the RTL and reduce the working time of the subsequent comprehensive analysis.

[0060] Embodiment 2

[0061] Figure 3 1 is a flow chart of a method for determining the direction of a bidirectional port provided according to Embodiment 2 of the present invention. This embodiment is a further refinement of the above technical solution. The technical solution in this embodiment can be combined with each optional solution in one or more of the above embodiments. Figure 3 As shown, the method includes:

[0062] Step 310: Obtain a target circuit diagram designed by register transfer language RTL, and determine the bottom layer module of the target circuit diagram.

[0063] Optionally, in this embodiment, obtaining a target circuit diagram designed by a register transfer language RTL and determining the underlying modules of the target circuit diagram may include: obtaining the target circuit diagram from a target database before performing a comprehensive analysis on the target circuit diagram; parsing the target circuit diagram to obtain the modules of the target circuit diagram and the connection relationships between the modules; and determining the underlying modules of the target circuit diagram based on the connection relationships between the modules.

[0064] Among them, the target database can be a database system that uses a parser or tool to create and manage design data, which can store information extracted from design files of hardware description languages ​​​​(such as SystemVerilog or VHDL) and used in further processing, analysis or verification processes; in this embodiment, the target circuit diagram designed by RTL can be stored in the target database, which can facilitate subsequent direct processing of the target circuit diagram and save the time required to convert the target circuit diagram by storing it in other databases.

[0065] In an optional implementation of this embodiment, after the target circuit diagram is obtained through RTL design, that is, before the target circuit diagram is comprehensively analyzed through a comprehensive analysis tool, the designed target circuit diagram can be obtained from the target database.

[0066] Furthermore, the acquired target circuit diagram may be parsed to obtain the modules of the target circuit diagram and the connection relationship between the modules; it should be noted that in this embodiment, the module may also be referred to as a netlist.

[0067] Furthermore, the underlying module of the target circuit diagram can also be determined based on the connection relationship between the modules, that is, the connection relationship between the netlists; illustratively, if the target module in the target circuit diagram only contains the upper-level modules but not the lower-level modules, then the target module can be determined as the underlying module.

[0068] Step 320: Determine whether the bottom-level module is a basic circuit element.

[0069] The basic circuit element may be a basic logic gate, a storage element, a buffer or a tri-state gate.

[0070] Optionally, in this embodiment, after determining that the underlying module is obtained, the circuit elements constituting the underlying module can be further determined, and it can be further determined whether these circuit elements are basic circuit elements; if it is determined that the circuit elements of the underlying module include basic circuit elements such as basic logic gates, storage elements, buffers or tri-state gates, then the underlying module is determined to be a basic circuit element, otherwise, it is a non-basic circuit element.

[0071] Step 330: When it is determined that the bottom-level module is a basic circuit element, determine that the direction of the first bidirectional port of the bottom-level module is an output direction.

[0072] Step 340: Determine a first port connection line connecting the second bidirectional port to the first bidirectional port of the bottom module; and determine a direction of the first port connection line based on a direction of the first bidirectional port.

[0073] Optionally, in this embodiment, after determining the direction of the first bidirectional port of the underlying module, the port connections associated with the second bidirectional port of the upper module connected to the underlying module can be determined, that is, the connections between each first bidirectional port and each second bidirectional port, and further, the direction of each port connection can be determined.

[0074] Optionally, in this embodiment, the second bidirectional port of the upper module and the first port connection of the bottom module may be preferentially determined. Further, the direction of the first port connection may be determined based on the direction of the first bidirectional port. Exemplarily, the first port connection may be Figure 2The light blue top_a or top_b in FIG. 1 is not limited in this embodiment.

[0075] Optionally, in this embodiment, determining the direction of the first port connection based on the direction of the first bidirectional port may include: determining whether the first port connection includes other driving sources; if it is determined that the first port connection does not include other driving sources, then when the direction of the first bidirectional port is determined to be an output direction, the direction of the first port connection is the output direction; or, when the direction of the first bidirectional port is determined to be an input direction, the direction of the first port connection is the input direction.

[0076] In an optional implementation of this embodiment, after determining that the first port connection is obtained, it can be further determined whether the first port connection contains other driving sources, wherein the other driving sources can be one or more of a driver program, a clock signal source, an analog signal source or a digital signal source, which is not limited in this embodiment.

[0077] In an optional implementation of this embodiment, if it is determined that the first port connection does not contain other driving sources, then when the direction of the first bidirectional port is determined to be the output direction, the direction of the first port connection is also the output direction; when the direction of the first bidirectional port is determined to be the input direction, the direction of the first port connection is also the input direction.

[0078] In another optional implementation of this embodiment, if it is determined that the first port connection includes other driving sources, the first port connection direction needs to be determined based on the driving conditions of the other driving sources and the direction of any bidirectional port.

[0079] Step 350: Determine the direction of the second bidirectional port based on the direction of the first bidirectional port and the directions of the connection lines of each port.

[0080] In this embodiment, determining the direction of the second bidirectional port based on the direction of the first bidirectional port and the directions of the connection lines of each port may include: if it is determined that the directions of the connection lines of the first bidirectional port and the second port are consistent, then determining that the direction of the second bidirectional port connected to the second port is consistent with the direction of the first bidirectional port.

[0081] In an optional implementation of the present embodiment, if it is determined that the directions of the connection between the first bidirectional port and the second port are consistent, then the direction of the second bidirectional port connected to the second port is determined to be consistent with the direction of the first bidirectional port, that is, if it is determined that the directions of the connection between the first bidirectional port and the first port are both output directions, then the direction of the second bidirectional port is also the output direction; if it is determined that the directions of the connection between the first bidirectional port and the first port are both input directions, then the direction of the second bidirectional port is also the input direction.

[0082] In an optional implementation of the present embodiment, after determining the port direction of the second bidirectional port, the direction of the bidirectional port of the upper-level module connected to the second bidirectional port can be further determined. According to this method, the directions of all bidirectional ports in the target circuit diagram can be determined from bottom to top.

[0083] The solution of this embodiment, when it is determined that the first port connection between the first bidirectional port and the second bidirectional port of the upper module does not contain other driving sources, if the direction of the first bidirectional port is determined to be the output direction, then the direction of the first port connection is the output direction; if the direction of the first bidirectional port is determined to be the input direction, then the direction of the first port connection is the input direction. The direction of the bidirectional port of the upper module of the bottom module can be quickly determined, providing a basis for obtaining the directions of all bidirectional ports of the target circuit.

[0084] In order to better understand the method for determining the direction of a bidirectional port involved in this embodiment, Figure 4 FIG. 1 is a flow chart of another method for determining the direction of a bidirectional port provided according to Embodiment 2 of the present invention. Figure 4 As shown, sub, add and Top are modules; sub_a, add_a, add_b, top_a and top_b are bidirectional ports matching the modules respectively; in this embodiment, module sub can be used as a black box. If sub is a basic circuit element (primitive), it can be inferred that the direction of sub_a is the output direction. When traversing to add_a, it is necessary to traverse all bidirectional ports and port references of the port connection. If the directions are all output directions, add_a is inferred to be the output direction. If there are bidirectional ports or port references with the direction as the input direction, the design has multiple driving sources. Similarly, for point c1, when add_a is inferred to be the output direction, top_a is the output direction. If there are no multiple driving sources in the design, top_b is also the output output direction.

[0085] Based on the same method, if it is determined that sub_a is not pritimive and sub_a is already the bottom layer, then sub_a should be inferred as an input port, and add_a and top_a are both input ports. If there are multiple driving sources, the port inferred as the output port will be traversed and find that there is also input in the input direction, and it needs to be processed by multi-driving technology, which is not specifically limited in this embodiment.

[0086] The solution of the embodiment of the present invention infers the direction of the bidirectional port through RTL design, and determines the bidirectional direction before the synthesis of the synthesizer, thereby reducing the complex program of the synthesizer synthesis. Some synthesizers are unable to synthesize the bidirectional port. From the technical effect aspect, the bidirectional port direction is inferred through RTL design, which technically reduces the difficulty of analyzing the bidirectional code, reduces the synthesis time of the synthesizer, and reduces the resources occupied by the synthesis.
