Title: HSPICE error: reference not found Post by jszair on Jan 31st, 2011, 1:17pm Hi all, I run into an error in hspice saying that my reference is not found. But i included the model file and the simulation log also shows the model file is included. Also, the model didn't set lmax/min or wmax/min... Please help. THanks! error message: -------------------------------- **error** reference 0:nmos not found, or instance width or length does not fit into the wmax/wmin or lmax/lmin range. it was referenced in element 0:mn the channel width= 1.000E-04 and length= 3.500E-07 the line number was 11 -------------------------------- here's the spice deck .inc 'tsmc018.sp' .param ds=0.9 .param gs=1 vdsn vdn 0 dc 'ds' vgsn vgn 0 dc 'gs' mn vdn vgn 0 0 nmos L=.35u W=100u .op .options nomod dccap post brief .dc gs 0.2V 1.2V 10mV and the model file (too long to be included) is attached, (change the extension to sp) |
Title: Re: HSPICE error: reference not found Post by haykp on Jan 31st, 2011, 10:56pm Hi, Most probably you have specify the channel length or width that doesn't fit into Lmin< L < Lmax or Wmin <W<Wmax. So check whether your given W or L fit into that range. |
Title: Re: HSPICE error: reference not found Post by jszair on Feb 1st, 2011, 8:05am There is no lmax/wmax or lmin/wmin in the model file. .35 micron length and 100 micron width are very normal W/L number... |
Title: Re: HSPICE error: reference not found Post by Geoffrey_Coram on Feb 1st, 2011, 9:57am Is the .inc on the first line? Remember, Spice treats the first line as a comment. (I once had a .temp command as the first line, and the simulator printed that comment several times through the log file, which I took to mean it had used that temp, but really it was just printing the comment.) Also, TSMC is probably not going to like you posting proprietary information on a public forum ... |
