common/placer1: In random pick, only use grid if there is more than 64 BELs
 2018-11-20 10:11:21 +00:00
Maik Merten e167043e73 add "randomize-seed" command-line option 2018-11-19 19:45:12 +01:00
Sylvain Munaut d6fd0e7e5b common/placer1: In random pick, only use grid if there is more than 64 BELs 
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.

Mateusz Zalega d03291eeb1 gui: improved FPGAViewWidget::paintGL() performance 
Profiling revealed that memcpy() in QOpenGLBuffer::allocate() had been taking
the most time during paintGL() calls. I've been able to take the CPU usage
down to about 1/4 of its previous values by caching elements in VBOs and
updating them only after subsequent calls to renderGraphicElement().

This commit also includes changes to jsonparse to allow it to
1) recognize ports with no connection, and set their net pointers to NULL
2) recognize designs with a ports node rather than a ports_direction

The rule checker has also been modified to accommodate possible NULL netlists

The ice40 chip now also has iterator operations ++bi and bi++.
