Description

When simulating SPI-4.2 Lite design, I receive the following error: 

 

"# ** Error: /X_ODDR HOLD Low VIOLATION ON D1 WITH RESPECT TO C;"

Solution

This issue is due to ODDR violations occurring before the clocks are stable and locked. 

 

These messages can safely be ignored if SnkClksRdy or SrcClksRdy has not been asserted yet.
