Hello, I'm trying to implement source-synchronous output from Spartan-6. So I use a constraint to place output data registers into IOBs, and clock goes through ODDR2. So now clock and data switch almost simultaneously, but the downstream device requires a hold time of 1ns, how can I achieve that? Or I shouldn't use IOBs for data output, but then I won't be able to control the skew of the data? Thanks
