Miodrag Milanovic ccbe2dd18d Add reading attributes to nets from json 2019-06-01 11:41:50 +02:00
whitequark a0c9a70a5e When choosing between labels for one net, always prefer ports. 
1. Ports are already used in PCF and LPF files, so it is natural
that the developer would use them for constraints as well.

2. Unpredictable (the set of netlabels nextpnr looks at depends on
the optimizations during synthesis) net naming makes it impossible
for code generators like nMigen to reliably apply clock constraints.
