AR# 7700: 2.1i ngdanno warning : ngdexpander : 5 - STARTUP symbol... can be ignored
2.1i ngdanno warning : ngdexpander : 5 - STARTUP symbol... can be ignored
Keywords : ngdanno, STARTUP, ngdexpander, 5
Urgency : Standard
General Description : The back annotation program, ngdanno, produces the following warning when the STARTUP or STARTUP_VIRTEX block is used in a design : "Warning : NgdExapnder : 5 - the STARTUP symbol '$I304': The following pins were connected on the outside of block '$I304' but left unconnected within the block: CLK"
This warning is safe to ignore. Ngdanno does not simulate the CLK input to STARTUP, so the warning has no real meaning. The warning will be eliminated in a future software release.
