Hello!
I'm working on simulating this EVM using PSpice for TI: https://www.ti.com/tool/PMLKBUCKEVM#tech-docs
Specifically, the TPS54160 section; I'm using the schematic given in the experiment book as a reference, with the specific configuration detailed in experiment 1, on page 30.
There are two issues I'm running into at the moment. The first is that the diode used in the design, B260-13-F, is not available in the model library; while a SPICE model can be found online it's a .txt file with a basic SPICE .model statement with diode parameters. Is there a convenient way to integrate this into my design, or to modify the PSpice diode component to match?
Second of all, when I run a basic bias point with the native diode model at 24Vdc input (well within the EVM's tolerance) the simulation stalls out with the following message:
I've fiddled with the ABSTOL and VNTOL options in the simulation profile, and I've attempted to turn on auto-converge based on another question on this forum. Neither seems to have helped. This problem disappears for low input voltages (~6V) but the output values this produces aren't right; if I've set things up correctly, Vout ought to be 3.3 V.
