Title: can't plot terminal currents (dc analysis) - no waveform supplied Post by oermens on Feb 25th, 2009, 9:47am as the title says, when i try to plot terminal currents from the results of dc analysis, cadence says ERROR: /M0/D is not a kept output. in spectre save options, the 'save', 'pwr', 'currents' are set to 'all' and 'userprobes' is set to 'yes'. the result is there in result browser, but i can not get it from ADE->results->direct plot->main form or dc. however i can plot the transient results from direct plot menu. i'm working in tsmc 180nm kit, but in ibm 130nm kit i don't have this problem. any ideas? this only happens for instances from the tsmc pdk library. simulator version: $ spectre -V @(#)$CDS: spectre version 6.1.1 06/17/2007 07:20 (usim440-24) $ $ spectre -W sub-version 6.1.1.424 $ icfb -V @(#)$CDS: icfb.exe version 5.1.0 06/20/2007 02:40 (cicsun11) $ $ icfb -W sub-version 5.10.41_USR5.90.69 |
Title: Re: can't plot terminal currents (dc analysis) - no waveform supplied Post by Geoffrey_Coram on Feb 26th, 2009, 6:28am Could be that M0 is a subcircuit, and you need to try to plot M0/M/D (assuming M0 contains a MOS named "M" along with perhaps a diode). |
