And this is why I decided to write this blog post, to take a deeper look at what it actually does.Ī convergence problem means that the difference (in voltages) between the simulation results of one iteration and the following one are not small enough implying an inaccuracy in the given solution. I am sure many of us just click 'yes' once the convergence assistant dialog box shows up for the first time. In some cases, the circuit might be too complicated for the SPICE simulator to converge with the default settings and this is why the convergence assisstant is also included in Multisim. This is why the default simulation settings in Multisim define tight enough conditions to assure quality results. Of course, the accuracy of the results depends on the settings of the SPICE simulation. The Multisim development team has put great efforts in enhancing this simulation environment and adding features to it for optimized analog and mixed-mode simulations. As you may already know, NI Multisim uses SPICE as its core algorithm for solving differential equations that model circuit components.
