Title: spice3f5 bsim4.4.0 model help Post by m_saibhushan on Jun 3rd, 2005, 4:09pm hi all, I have installed spice3f5 on my linux machine and tried to include bsim4.4.0 model into the installation. The build and installation process went smoothly but I am not sure if the bsim4.4.0 model is actually incorporated into my installation. If anybody is familier with spice installation, please tell me what I can do to make sure of it. For the installation, i modified the conf/defaults file to include the bsim directory name (bsim4) and placed the bsim4.4.0 directory in the ~/src/lib/dev directory with all the other devices. I renamed the directory to bsim4 to match with the conf/defaults file. I have tried executing simple spice netlists and they are working, but transistor models are generating errors saying the parameter is undefined. thanks, |
Title: Re: spice3f5 bsim4.4.0 model help Post by Geoffrey_Coram on Jun 6th, 2005, 6:24am Look in the directory src/lib/inp at the files "inp2m.c" and "inpdomod.c" This is where spice maps "nmos level=4" to bsim1, etc. You need to pick a level for bsim4. |
Title: Re: spice3f5 bsim4.4.0 model help Post by Geoffrey_Coram on Jun 30th, 2005, 5:27am One follow-up: the code in "inpfindl.c" only looks for levels 0-9. If you have a two-digit level (14 is often chosen for bsim4), then you need to make the appropriate modifications here. |
