Other Parts Discussed in Thread: PSPICE-FOR-TI,
Specifically this item: TPS7H4001-SP PSpice Worst-Case Analysis (WCA) Model (Rev. A)
Talked to a friend, he said the model loads and runs in Cadence PSpice, but that does not help me. It needs to run in TI PSpice (I do not have access to this Cadence tool).
Moreover he said, there is no simulation set-up for this model... And the transient results are all over the place (changes a lot based on settings). I looked into the unencrypted model. This model looks like an ad hoc table-based representation of the TPS7H4001 component. It should run fast and the sensitivity w.r.t. to sim settings may be because whoever assembled this model did not test very well; there are no d_by_dt aspects inside the model. But there are small to large capacitances in the test, so dunno… I suspect only need to tighten PSpice default time step a bit?
If an updated/fixed model can be provided, please also provide the test with sim set-up so I can see if this works properly.
Anyway... Hope you folks can help with this.
Thanks,
Bryan
