Problem Title:
M1.37 ngdbuild - ERROR:bascp - Could not find NET 'NET entry is '%s'
Problem Description:
Urgency: Standard
Reference #: 18723, 100076
General Description:
A problem exists with I/O locations embedded into multiple
levels of hierarchy. Ngdbuild reports an error on all signals
that are embedded in 3 levels of hierarchy. Ngdbuild does handle
signal names that are embedded in 1 to 2 levels. However,
fails with 3 or more.
Solution 1:
The workaround is to list the offending locations from the
.ucf file into the .pcf file after the "SCHEMATIC END ;"
statement. For example, the UCF file syntax:
NET "CPORT_5/CYCLOG2/IN_WR" LOC = "P173";
In the .pcf file, pinout constraints are written after the
"SCHMATIC END ;" statement to preserve pinout for future
design iterations. The PCF file syntax for our example:
COMP "CPORT_5/CYCLOG2/IN_WR" LOCATE = SITE "P173" ;
