problem in spectre

minci

 hi,there

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

<<<<Stack Trace>>>>

(....in ibmPdkaddibmPdkLibProperties....)

ibmPdkaddibmPdkLibProperties()

ERROR

 

 

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

    i have changed the  CDS_Netlisting_Node to CDS_Netlisting_Mode,but the problem is still here.

    then i followed Andrew's instruction to recreate the netlist,then it works!

    Even when i creating a new library and drawing a new schematic,i dont have to recreate it like above again.

     

    I think if you just do Simulation>Run you will get the error because it is using the netlist created with the wrong netlister, however Simulation>Netlist and Run should work. For the new cellviews, since you have set CDS_Netlisting_Mode correctly you won't have to recreate since it has already been created correctly. You would use Recreate if you've made changes to the schematic, or in your case, want to use a different netlister.
