xilinx multiplier
Hi,
I'm using the "Multiplier Generator V7.0" IP Core to calculate the squared magnitude of a complex number a+jb, i.e. I calculate a^2+b^2.
To calculate a^2 and b^2 I use two of the mentioned multiplier cores. When I do a behavioral simulation everything is OK.
When I simulate the placed and routed model, the result is also OK, but shortly before the correct a^2 or b^2 is stable, there are fast changes in the values of a^2 and b^2.
What's the problem ?
Regards,
Osbourne
