[0035] It should be noted that in the logical layout stage, the relative positions of various ports and modules in the integrated circuit schematic have been determined, and the physical layout further determines the physical coordinates of various ports and modules on this basis.
[0036] In some embodiments, the acquiring of all ports to be laid out and determining the initial physical coordinates of the ports to be laid out includes:
[0037] Get all ports to be laid out, use the vertical coordinate corresponding to the leftmost column of the layout area as the vertical coordinate of the input port among all the ports to be laid out, use the vertical coordinate corresponding to the rightmost column of the layout area as the vertical coordinate of the output port among all the ports to be laid out, and determine the horizontal coordinate of the input port and the horizontal coordinate of the output port according to the preset front-to-back order of all the ports to be laid out.
[0038] In a specific embodiment, all ports to be arranged include two types of ports, namely input ports and output ports, wherein input / output ports are also counted as input port types. The ordinate corresponding to the leftmost column of the layout area is used as the ordinate of the input port among all ports to be arranged, and the ordinate corresponding to the rightmost column of the layout area is used as the ordinate of the output port among all ports to be arranged. For example, the ordinate corresponding to the leftmost column of the layout area may be Y=0. According to the preset front-to-back order of all ports to be arranged, the horizontal coordinates of the input port and the horizontal coordinates of the output port are determined from top to bottom, so as to determine the initial physical coordinates of all ports to be arranged.
[0039] S102, determining the physical coordinates of the current module according to a direct front-end drive port, a direct rear-end drive port or a front-end drive module of the current module;
[0040] In some embodiments, determining the physical coordinates of the current module according to a direct preceding drive port, a direct succeeding drive port, or a preceding drive module of the current module includes:
[0041] Determine whether there is a direct predecessor port of the current module among all the ports to be laid out. If so, determine the physical coordinates of the current module based on the direct predecessor port. If not, determine whether there is a direct successor port of the current module among all the ports to be laid out. If so, determine the physical coordinates of the current module based on the direct successor port. If not, determine whether there is a predecessor module for the current module. If so, determine the physical coordinates of the current module based on the predecessor module.
[0042] In a specific embodiment, based on the connection relationship of the current module (the connection relationship with the port to be laid out), it is determined whether there is a direct predecessor port of the current module among all the ports to be laid out. If so, the physical coordinates of the current module are determined based on the direct predecessor port. Specifically, left alignment can be performed based on the direct predecessor port to determine the physical coordinates of the current module.

If so, the physical coordinates of the current module are determined based on the direct rear-end port. Specifically, right alignment can be performed based on the direct rear-end port to determine the physical coordinates of the current module. If not, it is determined based on the connection relationship of the current module (the connection relationship with other modules) whether there is a predecessor module for the current module. If so, the physical coordinates of the current module are determined based on the predecessor module. Specifically, left alignment can be performed based on the predecessor module to determine the physical coordinates of the current module.

[0045] In a specific embodiment, if the current module does not have a predecessor module, the current module will not be physically laid out (physical coordinates determined) temporarily. After the physical coordinates of all modules with direct predecessor ports, direct rear drive ports or predecessor modules are determined, the physical coordinates of the current module are determined based on all modules with determined physical coordinates. Specifically, the current module can be placed behind all modules with determined physical coordinates, and all modules with undetermined physical coordinates can be placed in turn behind all modules with determined physical coordinates to determine all modules with undetermined physical coordinates.
[0046] In some embodiments, after the physical coordinates of all modules are determined, the method further includes:
[0047] According to the physical coordinates corresponding to each module, the corresponding modules are sorted. After all the modules are sorted, the physical coordinates of the modules are adjusted according to the relative order between the modules and the space occupied by the modules.
[0048] In a specific embodiment, the modules are sorted according to the physical coordinates (initial physical coordinates) corresponding to each module. After all the modules are sorted, the physical coordinates of the modules are adjusted according to the relative order between the modules and the space occupied by the modules to obtain the final physical coordinates of the modules. When adjusting the physical coordinates of the modules, it is necessary to avoid overlapping of the physical coordinates between the modules.

[0051] If the current port to be arranged is an input port, then judging whether there is a rear-drive module for the current port to be arranged according to the connection relationship between the current port to be arranged and the module, and if so, determining the best rear-drive module for the current port to be arranged according to the distance between the physical coordinates of the rear-drive module and the initial physical coordinates of the current port to be arranged;
[0052] If the current port to be arranged is an output port, then based on the connection relationship between the current port to be arranged and the module, it is determined whether there is a predecessor module for the current port to be arranged; if so, the best predecessor module for the current port to be arranged is determined based on the distance between the physical coordinates of the predecessor module and the initial physical coordinates of the current port to be arranged.
[0053] In a specific embodiment, the port corresponding to the leftmost column of the layout area is an input port, and the port corresponding to the rightmost column of the layout area is an output port; if the current port to be laid out is an input port, then based on the connection relationship between the current port to be laid out and the module, it is determined whether there is a rear-drive module for the current port to be laid out. If there is, there may be multiple rear-drive modules at this time, and the best rear-drive module of the current port to be laid out can be determined based on the distance between the physical coordinates of the rear-drive module and the initial physical coordinates of the current port to be laid out. Specifically, the rear-drive module closest to the initial physical coordinates of the current port to be laid out is used as the best rear-drive module. If the current port to be laid out is an output port, then based on the connection relationship between the current port to be laid out and the module, it is determined whether there is a front-drive module for the current port to be laid out. If there is, there may be multiple front-drive modules at this time, and the best front-drive module of the current port to be laid out is determined based on the distance between the physical coordinates of the front-drive module and the initial physical coordinates of the current port to be laid out. Specifically, the front-drive module closest to the initial physical coordinates of the current port to be laid out is used as the best front-drive module.
[0054] In a specific embodiment, if the current port to be arranged is an input port, after obtaining the best rear-drive module of the current port to be arranged, the final physical coordinates of the current port to be arranged are determined according to the physical coordinates of the best rear-drive module. Specifically, the best rear-drive module is left-aligned with the current port to be arranged to determine the final physical coordinates of the current port to be arranged. If the current port to be arranged is an output port, after obtaining the best front-drive module of the current port to be arranged, the final physical coordinates of the current port to be arranged are determined according to the physical coordinates of the best front-drive module. Specifically, the best front-drive module is right-aligned with the current port to be arranged to determine the final physical coordinates of the current port to be arranged.
[0055] In some embodiments, the integrated circuit schematic physical layout method further includes:
[0056] If the current port to be arranged does not have the subsequent drive module and the preceding drive module, the final physical coordinates of the current port to be arranged are determined according to the final physical coordinates of the previous port to be arranged of the same type.
[0057] In a specific embodiment, if the current port to be laid out has no connection relationship, that is, there is no rear-drive module and front-drive module, the final physical coordinates of the current port to be laid out are determined according to the final physical coordinates of the previous port of the same type to be laid out. Specifically, the minimum spacing is maintained and it is placed below the previous port (the same type of port); as an example, if the current port to be laid out is an input port, the final physical coordinates of the current port to be laid out are determined according to the final physical coordinates of the previous input port. If the current port to be laid out is an output port, the final physical coordinates of the current port to be laid out are determined according to the final physical coordinates of the previous output port. It should be noted that the final physical coordinates of all ports can also be adjusted after the final physical coordinates of the current port to be laid out to avoid overlapping of the physical coordinates of each port.

[0059] The integrated circuit schematic physical layout method provided by the embodiment of the present invention can effectively maintain the order of ports in the design. When a module needs to be expanded in the schematic and the internal design of the module and the design of the level where the module is located are viewed at the same time, the port order is maintained so that the physical layout of the internal ports after expansion is consistent with the port order when not expanded, which can effectively avoid layout fluctuations at the level where the current module is located, can more quickly and efficiently feedback design information, facilitate the modification and maintenance of the design, and improve integrated circuit design efficiency.
