Simulating Predictive models in Cadece Spectre
Jan 21st, 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.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.

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... Cheesy
