TINA/Spice/UCD3138: ucd3138

Part Number: UCD3138
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

A question: how would I make an open loop power stage that works well in TINA-TI  interact with UCD3138 outputs of PWM and close the loop by getting the feedback parameters form TINA-TI?

So the computer has to run both concurrently: power stage produces current sense and feedback, feeds them to CCS computing online  to update PWM. There has to be some sort of synchronized operation of the two.

any ideas?

Wont this be a very powerful  method to debug through virtual closed loop system and understand the whole system much better? Even debug both code & the power stage glue logic, sensor parameters etc.

thnx
