ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile c code for the API of spice simulators.
Updating prev review, I complained about no auxconf/config.sub, but this is apparently created by script autogen.sh. I did not find reference to this script. For now, I'll consider myself not qualified to rate this package until I learn more. I found reference to autogen.sh in the ng-spice adms package on sourceforge
