Title: Simulating Predictive models in Cadece Spectre
Post by rgnanadavid on Jan 21^st, 2007, 8:27am

Hi I tried simulating my design using the 65nm BPTM in cadence spectre. But the simulator returned with an error saying "level=54" not supported and also syntax error in parameters like " version,tnom, aigbacc,kt1 etc...". I generally simulate my design using UMC130nm foundary model files. But i wanted to try my design using the 65nm predictive models. Can u help me in fixing the problem...

level=54 sounds like you're using an HSpice model file ... which I guess should be OK since Spectre has a Spice parser. But maybe you can try level=14, which I think is the number for BSIM4 in Berkeley Spice (rather than 54 used by HSpice). You'll know if it works if you don't get warnings about unknown parameters.

Hi i just figured out the problem. The cadence version that i have is IC5033 and it does not preprocess the spice model file to spectre model file. So i used the 'spp' seperately and included the newly generated file in my simulation and it worked... :D
