Diamond:  Why is there a Timing Rule Check violation in the trace report on a ODDRX4B element for timing between the SCLK & ECLK inside this element?

This violation should not occur if the module is generated using IPExpress. If you are generating the module using IPExpress and continue to get this timing violation, check your preference file to make sure there is a FREQUENCY preference assigned on both the clocks going to the ECLK tree and to the SCLK tree.
