Convergence issues

Q. There are times when my simulations lead into convergence issues. How to deal with those convergence issue in PSpice for TI software?

A.  PSpice simulator relies on iterative solution method of Newton Raphson to solve nonlinear circuit equations. When this iterative method is not able to obtain a stable solution, it is reported as a convergence error.

PSpice offers Auto Convergence mode, which tries to achieve convergence or solution by intelligently tweaking different simulator options.

Refer – Here’s a forum thread to understand various common causes of convergence and different simulator options available to you in PSpice to solve those convergence errors

For in depth explanation of various simulator options to deal with convergence issues, please refer to the PSpice User Guide
