You say you have tested this on a xilinx spartan 6. How were you able to pass timing? I'm trying on a (admittedly small and lame 7-series artix speed-grade 1 device) but there is no way I can make it work (violations of several ns). There are substantial combinatorial chains in your design. Any thoughts?
