In EDK while generating the bit file, I got a timing constraint error which looks like this:
unning delay-based LUT packing...
ERROR:Pack:1653 - At least one timing constraint is impossible to meet because
component delays alone exceed the constraint. A timing constraint summary
below shows the failing constraints (preceded with an Asterisk (*)). Please
use the Timing Analyzer (GUI) or TRCE (command line) with the Mapped NCD and
PCF files to identify which constraints and paths are failing because of the
component delays alone. If the failing path(s) is mapped to Xilinx components
Now I amtrying to analyse the system.ncd file using the timing analyser and seems there is some problem with the ncd file. This is the error that I get:
EXCEPTION:Pds:Pds_PahFileConv.c:50:1.20 - Corrupt Database.
ERROR:TimingToolsC:387 - A system error occured when trying to launch the
process: trce /home/madhum/RA/edk_509/2_project/implementation/system_map.ncd
Wind/U X-toolkit Error: wuDisplay: Can't open display
How can I debug the .ncd file? This error doesn't lead me to anywhere I think there is some problem with my ncd file only since when I run another project's ncd file it runs fine.
any feedback on this is much appreciable.
