Avoiding Simulation Issues
General Troubleshooting for Simscape Models
If you experience a simulation issue, first read Troubleshooting Simulation Errors in the Simscape documentation
to learn about general troubleshooting techniques.
Note
As mentioned in the Product Overview, SimElectronics software does not have
the ability to model large circuits with dozens of analog components.
If you encounter convergence issues when trying to simulate a model
with more than a few tens of transistors, you may find that the limitations
of SimElectronics software prevent you from achieving convergence
with any set of simulation parameter values. |

Troubleshooting for Simscape Models that Include SimElectronics Blocks
There are a few techniques you can apply to any SimElectronics model
to overcome simulation issues:
Add parasitic capacitors and/or resistors (specifically,
junction capacitance and ohmic resistance) to the circuit to avoid
numerical issues. The Astable
Oscillator demo uses these devices.
Adjust the current and voltage sources so they start
at zero and ramp up to their final values rather than starting at
nonzero values.
Working with Simulink Blocks describes
how to avoid simulation errors in the presence of specific SimElectronics model
configurations.
