Description

Keywords: Map, Error, Microblaze, RLOC, Design Constraints

Urgency: Standard

General Description:
MicroBlaze built with configuration 5 (I and D OPB w/ OPB2OPBlite bridge) fails map with Pack error:

"ERROR:Pack:679 - Unable to obey design constraints (MACRONAME=microblaze_0,
RLOC=R-7C12.S0) which require the combination of the following symbols into a
single SLICE component:
LUT symbol "microblaze_0/microblaze_0_i/dopb_interface_i/dopb_dready_i"

This error is generated when the MicroBlaze system contains no LMB memory.

Solution

This issue will be resolved in the 6.1 EDK Release. Until that time, add the following constraint to your UCF file:

INST "microblaze_0/microblaze_0_i/dopb_interface_i/dopb_dready_i" USE_RLOC = FALSE ;

NOTE: You will need to update the path based upon the error message map prints.
