Associate PSPICE model to heterogenous part: is it possible?

eddoh

Just asking here since I did not find clear answer elsewhere, not even in the help files.
I am making a model for multiple channel OPAMP, and till now I believed the Heterogenous type was the fittest approach (for the two shared power pins).
But then I hit the wall trying to associate the PSPICE model [
Message: ERROR(ORCAP-2380): Part "U1A" is heterogenous. Heterogenous Parts are not supported in this flow.]

Same happens if I try with the whole part, instead of a section.

So, just to cut it short, PSPICE model association is possible only using 1 section models or multiple section homogenous models - not heterogenous?

Not sure if I am crafting the heterogenous parts wrongly instead.

Thanks

    Self reply.
    From the help "Associating pspice models to capture parts":
    "PSpice models can only be associated with homogeneous parts."

    Bummer. I was going to use heterogeneous parts to model a switching regulator with auxiliary LDO output - which is clearly not possible. I'll have to create a flat model now.

    Hi Eddoh,

    It could be done using tcl there is an app note available on one of the channel partners website however it need CIS to work or it might be on the cadence website but you need a current licence to access the cadence ones
