Subject: Merge runsimsoc2.sh into runsimsoc.sh
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3195eb2a577d6f292e12fd06ea6f62d234c85cd6;p=gram.git

Merge runsimsoc2.sh into runsimsoc.sh

The only difference was a different location of the ECP5 model files
and the use of python3. Make it so that both locations work, and
use python3 exclusively.
