After an LVS extraction run, the SOFTCHK db is flagged with a yellow exclamation mark in RVE, but the SOFTCHK db is missing.

 

There is also a warning in the LVS log.

 

WARNING: Stamping conflict in SCONNECT - Multiple source nets stamp one target net.
Net VSS is selected for stamping.
Rejected nets: 96

 

Pair up the commands SCONNECT and LVS SOFTCHK to get the SOFTCHK database

 

LVS REPORT OPTION S produces a warning and highlights the SOFTCHK database in RVE when an SCONNECT is executed that results in a stamping conflict.

However, an LVS SOFTCHK statement, paired to the SCONNECT statement, is required to create the geometric SOFTCHK database.

 

For example:

 

SCONNECT PTAP PWELL
LVS SOFTCHK PWELL UPPER MASK
