Title: Cadence 6.1 Plottign problem for device parameters. Post by ic_engr on Nov 4th, 2010, 9:05am Hello All, I have been successfully plotting device parameters like gm, gds, VTH using the extra file stating "save M1:gm" type statements in IC5.1.4.1 Recently I moved to IC6.1 and the same file does not give the parameters after running the simulation. In the output log file I am getting a warning: WARNING (SPECTRE-8061): `M1': Does not have a terminal named `gm'. in save statement. Any suggestions. Regards ic_engr |
Title: Re: Cadence 6.1 Plottign problem for device parameters. Post by Andrew Beckett on Jan 2nd, 2011, 2:51am I don't think this is anything to do with it being IC61 - the most likely explanation is that your model is actually a subckt model, and hence the actual transistor is inside a subckt. You'd probably need to change it to save M1.M0:gm (or whatever the transistor is called inside the subckt model). Presumably you are using different models in IC61 compared with IC5141. Regards, Andrew. |
