[Disksim-users] Hardware used for UDE and SATA emulation

No, it simulates the timings, but without any real data behind it.  
AFAIU disksim takes I/O access patterns and returns estimated timings  
for various storage systems (or single platters).

Does that emulated disk require some sort of cycle accurate timings  
WRT some real disk or storage system? That's probably the only point  
where disksim could be of use for you.

I don't consider an "old IDE host controller" to be an emulation. It's  
just an IDE controller. If it suffices, you don't need to emulate  
anything, do you?

If you are really more into hardware, you might want to look at  
various VHDL or Verilog projects on OpenCores, they provide some sort  
of IDE (i.e. ATA) controller at [1].
