2.12.1. Using ModelSim with an SOPC Builder-Generated System

If your hardware system was generated by SOPC Builder, running a software project in ModelSim is very similar to running it on Nios II hardware.

To run a Nios II software project in ModelSim, right-click on the application project name, point to Run As, and click Nios II ModelSim.

To debug a software project in ModelSim, right-click on the application project name, point to Debug As, and click Nios II ModelSim.
