Problem Title:
Map: Hard macro pin locking from ucf not supported
Problem Description:
Urgency: Standard
General Description: Hard macros can contain IOB components. These
components can not be locked to specific pin locations in the ucf file. For example
NET U1/XXXXX LOC = P14; will be ignored when the net is inside a hard macro.
Solution 1:
The only work around is to modify the pcf file. For example:
COMP "U1/xxxxx" LOCATE = SITE "P14" LEVEL 1 ;
Note: When hand editing the pcf file the user must be aware of the potential problems. The user must
verify that the site specified is not being used, this can cause PAR to error. Also, the user is re
sponsible to verify the comp name. If this is incorrect PAR will error.
