Cannot find any 32 bits or 64 bits executable version of "spectremdl".

Hello

I am trying to use spectremdl to do simulation. When I type spectremdl in interminal I get "Cannot find any 32 bits or 64 bits executable version of "spectremdl"." when I type "which spectremdl" I get the location of the file "spectremdl" at /opt/Cadence/Incisive14/tools/bin. Is spectremdl installed correctly on my computer?

Thanks

Wen
