TPS61378-Q1: simulation

Hello Takeshi,

The expert for this device is at the moment not available. He can have a look after Chinese New Year celebration.

The source is a transient source, so it is possible that this is the transient model and not the average model.

In the meantime, did you try to restart the model? 

Best regards,
Brigitte

Hi Takeshi-san,

I was able to run the simulation from the reference design in PSpice for TI.

We do have an issue with how the model was released. As a result, we are currently limited to 3 markers per simulation run. I disabled the EN marker for my run.

Please note the time. Your simulation is only running 35 us. The device hasn't moved yet in my simulation.

Here are the results for the Startup sim profile:

Hi David and Brigitte,

Thank you  for  your reply.

I could simulate as you did. 

But,It takes a long time to finish.(8minitues per 50% of simulation) 

Can it be more short time to finish without upgrading PC spec? 

Hi Takeshi,

There's always a trade-off between speed and accuracy. The risk of reducing accuracy is that the simulation might converge to the wrong state.

There's an article on the PSpice page that addresses how to modify the parameters that control the simulation.
