When I perform RC extraction with special nets in a hierarchical design. The tool (StarRCXT) faild to find those nets in sub blocks.
Nets defined in file star_cmd are in this format:
NETS: X0/X2/NET_3
NETS: X0/X2/NET_6
......
Anyone here can help me on this issue? Thanks a lot!
StartRC can only extract real "physical nets",
NETS: netname,
When you flatten the hierarchical netlist to flat netlist, the netname must be found in the flat netlist.
