ERROR: CPF file incomplete

Yemelya

Hi,

I started creating a CPF according to cpf_ref.pdf document from Cadence. But obviously I am missing something. But what?
The CPF and the error message attached below.

May be somebody has and could share a good (accomplished) example of CPF file for encounter to be a base to start with.

Thank you very much!

Regards,
-Boris

     Hi Boris,

    I have little experience with CPF but as I run in the same error message, I have learned that the message is due to a missing statement in the CPF file : update_nominal_condition. This statement makes the binding between library and power domain. With your name definition, you should add something like:

    update_nominal_condition -name high -library_set PD_VDD_set

     Best Regards

    Patrice
