PSpice - Tip of the Week: A quick comparison between Allegro PSpice Simulator Monte Carlo analysis and AA Monte Carlo analysis

1. The AA MC engine picks up the tolerances straight from the devices specified either by the RTOL on the device or the global tolerance variable. There is no separate setting in the Advance Analysis Profile. On the other hand, Pspice MC reads the dev and lot parameters defined on the model for getting tolerance information.

2. The Gauss distribution in Allegro PSpice Simulator Monte Carlo analysis generates a Gaussian distribution over a range of +/-3 sigma, based on the tolerance defined. There is also a Gauss User distribution that allows deviation from 1 to 9 sigma. Its default value is one sigma.

The AA MC uses the distribution files located at \tools\pspice\library\distribution\.

Very interesting..!!! but, what impact on results we would see when engine picks up the tolerances straight from the devices specified either by the RTOL on the device or the global tolerance variable vs the dev and lot parameters

There is no difference in results as both are Monte Carlo. However AA MC offers more number of statistical reports than PSpice MC and is also user friendly while defining the tolerance parameters.
