A current or voltage that reaches +/-1E10 indicates that the maximum value has been reached. Add a shunt resistor if necessary to keep them forward biased.ĥ: Try raising ITL1 to 500, RELTOL to 0.01, and using NODESETs.Ħ: Look for large currents for the problem devices and currents. A convergence problem can result when current is forced backward through diodes or pn junctions.ģ: Check that diodes are forward biased in the reported voltages for the last iteration. In the previous/current iteration voltage printout, note the largest voltages (as large as 1E10) to help find the root the problem.Ģ: Check the direction of independent and dependent current sources. out file to further localize the problem. Above functionality should avoid your most of the convergence problem but below are few troubleshooting guidelines for Convergence Failure:ġ: Examine the non-convergence error message in the. You could activate the AutoConverge option and run the simulation.
How can I troubleshoot convergence failures?Ĭommon causes Of Convergence failure in Allegro AMS Simulator (PSpice) are:įrom SPB 16.2 version onwards, you have a function called AutoConverge under Simulation Settings > Options > Analog Simulation, as shown below:
