* netlist: Add PseudoCell APIgatecat2022-07-081-3/+3
| | | | | | | | | | | | | | | When implementing concepts such as partition pins or deliberately split nets, there's a need for something that looks like a cell (starts/ends routing with pins on nets, has timing data) but isn't mapped to a fixed bel in the architecture, but instead can have pin mappings defined at runtime. The PseudoCell allows this by providing an alternate, virtual-function based API for such cells. When a cell has `pseudo_cell` used, instead of calling functions such as getBelPinWire, getBelLocation or getCellDelay in the Arch API; such data is provided by the cell itself, fully flexible at runtime regardless of arch, via methods on the PseudoCell implementation.

* Switch to potentially-sparse net users arraygatecat2022-02-273-22/+14
| | | | | | | | 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>

* archapi: Use arbitrary rather than actual placement in predictDelaygatecat2021-12-192-4/+6
| | | | | | | | | | | | This makes predictDelay be based on an arbitrary belpin pair rather than a arc of a net based on cell placement. This way 'what-if' decisions can be evaluated without actually changing placement; potentially useful for parallel placement. A new helper predictArcDelay behaves like the old predictDelay to minimise the impact on existing passes; only arches need be updated. Signed-off-by: gatecat <gatecat@ds0.me>
