Title: Error in Spectre simulation Post by Ankush Goel on Sep 15th, 2005, 11:54am Hi All, I ran the following command for a circuit simulation... spectre +cp -env artist5.0.0 +log ../psf/spectre.out -format psfbin -raw ../psf -I/home/ankush/tech_file/IBM_PDK/bicmos7wl/V1.3.1.0DM/Spectre/models/ input.scs The following was the error message I got: Error found by spectre during circuit read-in. ".bsource.va", line 13: "parameter real useii=0.0, pavc1=0.0, ppc=0.0, prhot=0.0, pavc3=0.0, temp=0.0, dtemp=0.0;<<--? " ".bsource.va", line 13: Error: real temp is redefined. spectre terminated prematurely due to fatal error. I am not able to locate the file bsource.va. Can anybody tell me where to find the path for the file. Thanks, Ankush |
Title: Re: Error in Spectre simulation Post by Paul on Sep 15th, 2005, 12:59pm Ankush, according to the error message, the filename is .bsource.va The leading "." means it is a hidden file in the Unix/Linux file system, i.e. it does not appear using ls. The option -la to the ls command however shows hidden files. I don't have access to Cadence right now, but it seems this should be related to the use of the bsource component for nonlinear resistors. http://groups.google.ch/group/comp.cad.cadence/browse_thread/thread/ffbcdeb689077001/432af310e5ede6a5? You can get more information by typing "spectre -h bsource", but I'm not sure that your problem is directly related to the bsource code. Probably Andrew will be able to help you out here... Paul |
Title: Re: Error in Spectre simulation Post by Geoffrey_Coram on Sep 19th, 2005, 6:29am I'll hazard a guess that ".bsource.va" is a Verilog-A description of a (customized?) bsource element provided in the IBM design kit. find /home/ankush/tech_file/IBM_PDK -name ".bsource.va" |
Title: Re: Error in Spectre simulation Post by Andrew Beckett on Sep 19th, 2005, 9:09pm Apologies for not responding sooner - I've been travelling a lot the last couple of weeks. From looking at this I would have guessed that you were using an old version of the simulator - probably from the very early days of bsource support in spectre (possibly from when it was only an engineering version). I see that you logged a service request, 33349726, with customer support - and they came to the same conclusion - the version you're using is from May 2003 - which was before bsource was fully released. That happend in IC5033, and as was found by the AE, this works in IC5033 versions and later. Regards, Andrew. |
