vhdl code for phase angle detection!!!!

[k.s]

pls suggest some coding techniques to write the vhdl code fr finding phase angle b/w 2 sq. wave signals same freq

k.s,

I imagine you have a sampling clock that is at least an order of magnitude greater that the signals you are trying to analyze?

If so, you could just use a simple counter.

Do an edge detect on one of the signals, and count until you see the edge of the other signal.
