 swerv.config            | Configuration script for SweRV-EL2  
+swerv_config_gen.py     | Python wrapper to run swerv.config, used by SweRVolf
 
 
 This script will generate a consistent set of `defines/#defines/parameters` needed for the design and testbench.  
 A perl hash (*perl_configs.pl*) and a JSON format for SweRV-iss are also generated.
