1.5i 4K MAP: ERROR:x4kma:387 - Unable to obey design constraints
Record #4606

Product Line: FPGA Implementation
Product Part: map
Product Version: 1.5i
Problem Title:
1.5i 4K MAP: ERROR:x4kma:387 - Unable to obey design constraints
Problem Description:
Urgency: Standard
e following symbols into a single CLB: FMAP symbol "FMAP_149" (output signal=hdlc_tx_C168) There are
more than two combinational outputs required. These symbols share the same LOC parameter.
Solution 1:
This general error indicates that map was unable to follow
some CLB packing instructions. One possible cause for this
error is a known problem where map will pull FMAPs into
CLBs because they drive the HMAP, without checking for
conflicts. This behavior can be disabled by setting the
following environment variable:
SET XIL_MAP_NO_FMAP_PACK = 1 (PCs)
setenv XIL_MAP_NO_FMAP_PACK 1 (Work Stations)
