| * Switch to potentially-sparse net users arraygatecat2022-02-273-46/+39
| | | | | | | | | | | | | | | | 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 predictDelaygatecat2021-12-192-14/+9
| | | | | | | | | | | | 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>

* Split nextpnr.h to allow for linear inclusion.Keith Rothman2021-03-153-10/+21
| | | | | | | | | | | | | | | | | | | "nextpnr.h" is no longer the god header. Important improvements: - Functions in log.h can be used without including BaseCtx/Arch/Context. This means that log_X functions can be called without included "nextpnr.h" - NPNR_ASSERT can be used without including "nextpnr.h" by including "nextpnr_assertions.h". This allows NPNR_ASSERT to be used safely in any header file. - Types defined in "archdefs.h" are now available without including BaseCtx/Arch/Context. This means that utility classes that will be used inside of BaseCtx/Arch/Context can be defined safely in a self-contained header.
