| * | Start making use of getBelPinsForCellPin APIgatecat2021-02-106-38/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * | Add getBelPinsForCellPin to Arch APIgatecat2021-02-107-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a basic implementation, without considering "M of N" arrangements (e.g. for LUT permuation where you only want to route to 1 out of 4/6 sinks) or using a type other than IdString to identify bel pins. But this is also enough to start working out where in nextpnr will break due to removing the 1:1 cell:bel pin cardinality, as a next step. Signed-off-by: gatecat <gatecat@ds0.me>

| * Remove the unused CellInfo::pins fieldgatecat2021-02-104-37/+0
|/ | | | | | | | | | | No arches ever actually used this to implement a Cell->Bel pin mapping, and in practice if any did try they would inevitably hit bitrot. This field had limited use in practice as it is necessary to also support cases where one cell pin maps to more than one bel pin. Removing this old field is the first step towards developing a new API for this. Signed-off-by: gatecat <gatecat@ds0.me>
