There is a difference between an oscilloscope and a logic analyzer. An
oscilloscope can be used to look at the actual analog output of
I posted two links a while ago on this mailinglist, quote...
When it comes to hardware development there is a Logic analyzer...
and a oscilloscope...
If you have a big enough FPGA you can fetch fast signals, even
internally in the FPGA. I used one in the altera environment when a
developed a VGA graphic RTL. Basically you could make a logic analyzer
in VHDL, that lat say a j-core could access. Then you could fetch
actual signal in the CPU, that is not simulated, but actual samplings
of internal signals.
