AI Technical Summary
In existing chip designs, manually modifying netlist files is labor-intensive, has low fault tolerance, and is prone to introducing secondary errors, especially during ECO modifications, which are difficult to complete efficiently.
By obtaining the modification path based on the connection relationship between abnormal nodes and nodes to be modified in the chip netlist, parsing the netlist file to obtain Cell and Pin objects, storing them in the data dictionary, and automatically identifying and modifying the netlist file according to the modification script.
This reduces the risk and workload of introducing secondary errors through manual modification of netlists, improves modification efficiency, and reduces the complexity of manual intervention.
