EPC spectre model to design NMOS is not working in ADEL Cadence Virtuoso Simulation

kaushikb · June 6, 2023, 5:46pm

Hello. I got stuck with this problem for a long back. I dont have any body to help. Please, help me. I am using the specter model of EPC2040 to design and simulate POWER NMOS. I made a symbol with the ports and included simulation path But the below error is coming during simulation:

Hi Kaushik,

The most recent version of the EPC2040 spectre model is EPC2040_V2.scs. Is that what you are using? If not, please try the updated model.

The model can be found at https://epc-co.com/epc/Portals/0/epc/documents/spectre-files/EPC2040_V0.scs.

Thank you,
Gordon

Hi Gordon,
Thank you for the reply. But the given link is not active. Below error is coming. Please, send the
EPC2040_V2.scs as text file if you have with you.

With Regards
Kaushik

My apologies. I had an error in the link. Correct link is:

Also uploaded here for convenience (EPC2040_V2.scs), as a .zip to meet attachment requirements

Hello Gordon,
Thank you very much for the support, I have simulated the symbol with the above mentioned file But the attached errors are coming!! Did I do any wrong method to create the symbol? I am elaborating the steps.

I have opened a file in the Cadence Library Manager.
Create 3 Pins there,
I have given Gatein as Input, Drainin as Output and Sourcein as Input.
I have made a symbol of the above cell view. .
I then Instantiated the symbol in the Simulation setup and the setup is ready for simulation.
I then opened ADEL window
I went to setup and clicked on model libraries. The model files are included there. Here the EPS2040.scs file is also included. Then I have run the simulation in ADEL of Cadence Virtuoso,
Fatal error is coming.

Could you please tell me where I am making a mistake? Is the above method ok? Kindly write to me step by step. if I have ignored any step.

I still do not understand how the EPC2040.scs is kept within the created symbol? These are two disjoint things, One side symbol and the other side EPC2040_V2.scs.

Kindly reply as I have been in trouble for a long time.

With Regards
Kaushik

I ran the EPC2040_V2.scs model But the below error is coming!! Please, look at it ASAP:
