* common/placer1: In random pick, only use grid if there is more than 64 BELsSylvain Munaut2018-11-191-0/+1
| | | | | | | | | | If you have a large grid and very few BELs of a given type, picking a random grid location yields very little odds of finding a BEL of that type. So for those, just put all of them at (0,0) and do a true random pick. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
