TPS22910A: PSpice for TI: Why only 3 markers when using only TI parts in the simulation?

Hans

Part Number: TPS22910A
Other Parts Discussed in Thread: TPS7A8101,

Hello,

when I download e.g. TPS7A8101 PSpice model I can simulate all nodes, correct? This also works with TPS22910A PSpice model. But when I combine both parts in a new project / schematic I need to use the markers and I am limited to just 3 nodes.

I understand that for external ICs there is a limitation in simulating several nodes in parallel, but this should not be limited in case I use just TI parts.

Thanks and Best Regards,

Hans

Hi Hans,

How did you add the TPS22910A model?

Thanks,
JC

Hi JC,

see my project below. I added the model like an external model. Is there another way?

Thanks and Best Regards, Hans

Hi Hans,

This project shows a successful simulation. Do you have one that failed?

Thanks,

Hi JC,

did you get this message after starting the simulation? When I press "Cancel" and restart the simulation it works...

When I press "OK" I get this error:

ERROR(ORPSIM-16583): Detected an imported model containing transistors or diodes. For such models, PSpice for TI supports a minimum of one and maximum of three traces. Reduce the number of traces and simulate again.

Thanks and Best Regards, Hans
