SN74LVC1G57: PSpice simulation error

ArTzy

Part Number: SN74LVC1G57

Hi Experts,

Good day!

I have this case from client who got the behavioral model for SN74LVC1G57, successfully imported it to PSpice and it looks fine on schematics. But when he is trying to make simulations, have this same Error: "ERROR(ORPSIM-15141): Less than 2 connections..." and it refers to SN74LVC1G57. How to handle this error?

I have attached the full project in zip file below.

Thanks for your support.

Regards,
Archie A.

Hi Archie,

I'll ask our PSpice modelling expert to take a look and get back to you.

Hi Archie,

Where did the client get the SPICE model from? Did he find it online on some E2E post?

I believe the PSPICE-TI only allows models from the TI library to be tested for free. Since he may have imported the model from elsewhere it is giving this problem. I will have to see on how to get the model added to the TI library.

Karan

Hi Archie,

It looks like the model being used was not designed for PSPICE.

I have made the required edits to it. Please let me know if it works now.

Hello Karan,

Thank you for a new simulation model.
But unfortunately client cannot simulate it due to problems with Cadence software. He is trying to make simulation, start getting this message from capture, see appendix below.
