How to generate noise in PSPICE?

Please take a look at the training videos that Cadence provides.

Additionally, here are a couple of previous answers to this question:

(+) PSpice: How to model noise with this scheme - Simulation, hardware & system design tools forum - Simulation, hardware & system design tools - TI E2E support forums

Art Kay has also created a slide deck covering some additional topics which does include noise analysis. Art_Kay_pspice_for_TI_2-22-2022.pptx
