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

説明

Keywords: Map, floorplanner, mfp , fp, constraints,

Urgency: Standard

Description: ERROR:x4kma:387 - Unable to obey design constraints which require the combination of the 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.






ソリューション

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)
