I am following the example in SpectreRF manual to simulate IP3 using swept PSS and PAC combination. I added output-referred IP3 as an output, using the Direct Plot form. When I run a nominal simulation using ADE L or XL, the IP3 output expression evaluates without any problem. But when I run a Monte Carlo analysis in ADE XL, the IP3 expression doesn't evaluate, and gives an error:

"Results pac are not available for ....../psf/mc1_separate/002. Use results() for a list of available results."

I also have other expressions using pss results. These evaluate correctly when I run the Monte Carlo without a pac analysis. But, when I include the pac analysis, 'some' of the pss-based expressions also fail to evaluate.

I searched on the Cadence support website etc, but couldn't find a solution that works.
