Title: How to run spectremdl about stb analysis? Post by holddreams on Apr 13th, 2009, 6:18am How to run spectremdl about stb analysis? I create a stb.scs file ,and run "spectre stb.scs", the result is correct, the loop gain, gain margin, phase margin are all right. However, during the spectremdl simulation, errors come up: FATAL(CMI-2010):Assertion failed in file 'dfistrm.c' at line 266. FATAL (SPECTRE-21):Assertion failed. Aborted ${APPBINPATH}/${PROGRAM}"$@"0<&3 The stb.scs: ....................... ...................... itest (vp fb) iprobe stbAnalysis stb start=1 stop=1e9 dec=20 probe=itest Alter_tt altergroup{ include "./model.scs" section=tt} Alter_ff altergroup{ include "./model.scs" section=ff} ................................ ............................... The stb.mdl: alias measurement stbrun{ run stbAnalysis } foreach vdd from {3.3}{ run Alter_tt run stbrun as stbrun_tt run Alter_ff run stbrun as stbrun_ff } Another question is how to manage the mdl file in order to measure the loopgain, phase margin, gain margin directly? Thanks in advance! |
