To summarize, this is what you need to do:
However if the default naming convention for module names is changed
during synthesis with DC/RC, then the above commands would not match
module names in LEC. To resolve this, you need run uniquification in LEC
to match the module names. This command is given after reading the
library and design files.
SETUP> uniquify -all -nolib
Basically, the uniquify command will match module names between golden and revised. Do this before running "write hier dofile".
