### Modelsim Setup

The main software tool we will use for labs and homeworks in this class is Mentor Graphics Modelsim, an HDL simulator.

• You may choose one of these options

• If you have Modelsim (SE/DE) installed on your PC and is working fine already, you do not have to install the Modelsim SE again. It does not matter for our course what modelsim tool version you are running.
• We are working on allowing EE 457 students to run Modelsim (now named Questasim) from USC's Virtual Desktop Interface (VDI). Please ask the instructor about this option if your PC cannot support Modelsim or you believe it is a preferable solution that using it on your own PC. Instructions for setting up the VDI may be found here (scroll down to the Usage Guidelines section. Not you should choose the General Desktop option and then under the start menu find Questasim.
• You can go to the SAL125 user-room and login on one of the Macs. Then open the Virtual Machines folder in Programs menu and clicking on the shortcut in the Programs menu labeled XP32-201108-PUVVADA. A window opens with a Windows-XP Desktop. You can invoke Modelsim from there.
