Simulate FPGA with other ICs

  A Video display simulator

Ahm ... I've certainly added C components to my test bench to create and simulate graphical interfaces. Here's one for VGA, and another for HDMI. This isn't really a "nobody does this" task. It's much easier to debug a graphical component graphically than it is to debug it with a wave file. Indeed, I owe my success in one particular video decompression example to being able to stop the simulation in real time in order to find and trace a bug.

  A demonstration showing how several components can be compsed to build a simulated spectrogram

and ... this is the Achilles heel of the whole approach. Sure, you can create a VGA or even HDMI simulation to test a scrolling raster, but it will take so long to do as to be quite painful. Sure, there are reasons for doing it, and times when you need to, but ... be prepared for the pain.
