Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0023] A circuit diagram design chip pin exchange method, which comprises steps:
[0024] S10, for the pins that need to be exchanged in the chip 1, go out according to the optimal way, and generate a relationship list A of the pin names and the corresponding initial network names in the first order. For pin 2 that can be exchanged in chip 1, it is routed according to the optimal outlet method, without considering the signal flow direction, so that the wiring channels of the chip can be fully utilized. Usually, the best way to go out is just to pull out the pin signal to the periphery of chip 1 (such as figure 1 shown). Of course, the optimal wiring method is different according to the specific circuit wiring situation. For example, sometimes it is necessary to lead the pin 2 of the chip to different lev...
