Hello everyone,

Recently I am using Cadence Spectre Version 16.1.0 to simulate a netlist in command line. However, I met the error when reading the library model file:
Reading file: /home/grads/z/zhanxin/PowerDeliveryNetwork/IBM_90nm_models/IBM_PDK/cmos9sf/V2.2.0.1IBM/Spectre/models/design.scs

Fatal error found by spectre during circuit read-in.
FATAL (SFE-867): Unable to open the file `/home/grads/z/zhanxin/PowerDeliveryNetwork/IBM_90nm_models/IBM_PDK/cmos9sf/V2.2.0.1IBM/Spectre/models/design.scs'.

That circuit library file (design.scs) could be accessed via vim, so this excludes the possibility of path error. Is there anyone having experiences about how to solve it?

Thanks a lot!
Xin

Don't you run Spectre as distributed process ?

Confirm file permission.
Is it "rw-r--r--" or "r--r--r--" ?
 

The file format could be broken due to editor. Because some text editors may add some extra hidden characters into file and Cadence Spectre sees those characters even they are not visible.
I lived a problem with a model card file once due to a small "point". Check this out..
 

It seems that the 32-bit Spectre was started by default, which cause a file loading issue on a 64-bit machine. It is fixed by adding '-64' option.. Thank you guys anyway..
