* Switch to potentially-sparse net users arraygatecat2022-02-271-32/+30
| | | | | | | | This uses a new data structure for net.users that allows gaps, so removing a port from a net is no longer an O(n) operation on the number of users the net has. Signed-off-by: gatecat <gatecat@ds0.me>

* router1: Support for multiple bel pins per cell pingatecat2021-02-101-62/+78

* Start making use of getBelPinsForCellPin APIgatecat2021-02-101-5/+5
| | | | | | | | | | | | This replaces getNetinfoSinkWire with 3 new functions for different use cases. At the moment all existing code has been moved to getNetinfoSinkWire with phys_idx=0 so the build doesn't break; but this won't yet function properly with more than one sink. But it provides a base on which to work on refactoring the routers to support this case. Signed-off-by: gatecat <gatecat@ds0.me>
