Hi,
ive simulated my PLL in ltspice using basic digital elements,
results posted in abse
but I want to put it into a fpga as
Im using one for other stuff too,
I have this simulated in xilinx IDE,
but is there a way of simulating a fpga with a vco atatched ?
it would be nice to see what frequency it would work upto,
using the routed part and a circuit for a vco.
I dont want to divide the 2ghz VCO down more than necessary,
the charge pump outputs probably wont be able to go much
more than a few hundred Mhz i gues, but the toggle flops
might be able to do some of the dividing.
