M1.5 Map - M1.5 optimization performance decreases compared to M1.4 (CLB count increases in 1.5).


Keywords: map, optimization, clb, count

Urgency: standard

General Description:
Same design compiled in M1.5 has more CLB count that in M1.4.
Specified map options are the same in M1.4 and M1.5.


It has been found that the M1.5 optimization algorithm
sorts components differently than M1.4 and that for some
cases this results in a performance degradation. It is
possible to set an environment variable that will restore
the M1.4 sort and performance:

setenv XIL_MAP_COMPNOSORT TRUE (Work Stations)
