Integrated circuit wiring pre-judgment method

An integrated circuit wiring pre-judgment method relates to the integrated circuit technology, and comprises the following steps: 1) establishing an INT module internal corresponding relation table used for recording the corresponding relation between an input pin in an INT module and a connectable output pin of the input pin; 2) establishing an external corresponding relation table between the INT modules, wherein the external corresponding relation table is used for recording a corresponding relation between an output pin of each INT and connectable input pins of other INT modules; 3) generating a lookup table according to the connection relation tables in the step 1) and the step 2), the lookup table recording selectable connection lines from each INT module input pin to all INT moduleoutput pins; and 4) traversing the wiring netlist, judging whether optional connection lines exist or not according to the lookup table aiming at the starting points and the ending points of the wirenets in the netlist, and i
