Hardware Debug
This section provides debug steps for common issues. The ChipScope debugging tool is a
valuable resource to use in hardware debug.
General Checks
Ensure that all the timing constraints for the core were properly incorporated from the
example design and that all constraints were met during implementation.
•
Does it work in post-place and route timing simulation? If problems are seen in
hardware but not in timing simulation, this could indicate a PCB issue. Ensure that all
clock sources are active and clean.
•
If using MMCMs in the design, ensure that all MMCMs have obtained lock by
monitoring the LOCKED port.
