Dear sir, I am working on the virtex 6, XC6VLX550T FF1759 speed grade -1 , using finite state machines with high operands, (113 bits), in Galois field inverse theory. The problem I face is that I got such results : Timing Summary:
--------------- Speed Grade: -1 Minimum period: 1.430ns (Maximum Frequency: 699.301MHz) Minimum input arrival time before clock: 0.910ns Maximum output required time after clock: 0.789ns Maximum combinational path delay: No path found =========================================================================
Process "Synthesize - XST" completed successfully
When i sent my paper to one of the journals, one of the reviewers said that it is not possible that the virtex 6 goes beyond the 600Mhz. He said try the place and route, but even though, I am getting the same frequency...
Is is true that this frequency is a fake one or perhaps an error from the synthetize tool.
Best Regards
