Based on your feedback on our last poll, below are some tips to resolve Convergence error in PSpice
To calculate the bias point, DC sweep and transient analysis for analog devices PSpice must solve a set of nonlinear equations which describes the circuit's behavior.
In a few cases PSpice cannot find a solution to the nonlinear circuit equations and this is called a “convergence problem.”
Common causes Of Convergence failure in Allegro PSpice Simulator are:
Enable Auto Convergence options in case tool throws convergence error. You can enable auto convergence from Simulation Settings > Options > Analog Simulation, as shown below:
Above functionality should avoid your most of the convergence problems but below are few troubleshooting guidelines for Convergence Failure:
Once you have verified the circuit using above points and still getting convergence error, then check PSpice options for the type of convergence error as below
