Real-time? That's impressive. How fast a PC do I need to run, say, a
16-bit PWM generator at 30 MHz?

Then it's not running real-time, is it?

It doesn't matter how fast your PC is. Of course it will be a
simulated 30 Mhz. He didn't say it was an Emulator, just a
Simulator.

Then it won't be real-time.
