I am having problems in using Netgen for LVS to compare the two netlists from Magic7.1 (nor.sim) and Xcircuit3.1 (nor.sim). On the NetGen1.1 commad: which command to write in order to lvs the two netlists? I've successfully simulate the two netlists indivisually using IRSIM9.6. The outputs are OK for both. But when I use Netcomp to compare the both, the two netlists mismatch. Here are some of the outputs. ====================================================================== [root AT atif Netgen]# netcomp DOT /magicfiles/nor.sim ./xcircuitfiles/nor.sim Strange token in .sim: 'R' line number 8 = 'R a_9_n5 238' Strange token in .sim: 'R' line number 10 = 'R a 1038' Strange token in .sim: 'R' line number 12 = 'R z 460' Strange token in .sim: 'R' line number 14 = 'R b 871' Strange token in .sim: 'R' line number 16 = 'R GND 441' Strange token in .sim: 'R' line number 18 = 'R Vdd 7055' Comparing cells: ./magicfiles/nor.sim (circuit 1) and ./xcircuitfiles/nor.sim (c ircuit2).
