i'm using ic5141 usr6 to design. In our new project,we'll use the IBM PDK
cmrf8sf.but i found the spectre in ic5141 is not supporting the new bsim4 model.Then,i use +csfe option in the usrCmdLineOption of spectre environment options,and this will work.
When i've re-installed my OS(RHEL4.8),however,i found this method doesn't work anymore.For example,if there is a nfet T1 in my circuit,the spectre will give the error message such as
"input.scs"13: T1 is an instance of an undefined model subcircuit.
Then,i have install the mmsim61.The first time,it works well.But,again,when i re-install the OS, the problem occurs again as the same with the first.i am sure i have set the right model library in the setup menu.
It's so weird and i dont know how to fix it.
And,there is also a problem when i use the command
IBM_PDK-> Library->Add IBM_PDK Lib Properties
the ciw shows the error message:
*Error*eval:unbound variable - addibmPdkLibProperitesForm
With this, i can not selecting the correct metals stack for the process. For DM this is "3-2" (three-thin, 2-thick); for LM use "6-2" (six thin, two thick). just as ibm instruct how to do when you create a new library.
anyone who can help me ? thanks a lot
