* When choosing between labels for one net, always prefer ports.whitequark2019-05-292-4/+13
| | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the PLLs drive global networks, we need to account for already existing and placed SB_GBs when trying to place/pack them. Theses can be user instanciated SB_GBs with BEL attribute, or SB_GB_IOs that got converted during the IO packing. This patch assumes that: - If a PLL is used the output A global network is always used, even if there is no connection to the global output pin - If a PLL with a singe output is used, then the B output global network is still free to be used by whatever.
