Hi,
When using the DDR functionality, is it the user's responsibility to provide the phase-shifted clocks or does the above mentioned primitive do this for me? The documentation is not very clear.
Although using a DLL to phase-shift is the best practice, can I get by just using an inverter between the two clocks? If so, does the Virtex-II IOB provide a "free" inverter (gets absorbed in the IOB)?
Comments?
