Part Number: TS3USB221A
Other Parts Discussed in Thread: TINA-TI, TS3USB221

Tool/software: TINA-TI or Spice Models

I am planning on using the TS3USB221 IBIS model for simulating the TS3USB221ARSER package, but I am receiving the warning below.

WARNING - Model TS3USB221_XDX_25_S not referenced in any [Pin], [Model Selector], [Driver Schedule] or [Series Pin Mapping] sections.

Thank you,

Sam

It does not. My question is regarding the warning.

Thanks,

Hi Sam,

This device models a series switch.

The fun thing about HyperLynx is that it doesn't allow both series switch and model selector statements to work together.

So, you'll note that in the switch statement, all of the 25 models are commented out, and the 33 models are active.

If you're looking to use the 2.5V models instead of the 3.3V models, uncomment the 25 and comment out the 33.

I'd also recommend commenting out the model selector entirely, and using the model names in the pin section.

Let me know if that isn't clear.

Regards,

David
