* Switch to potentially-sparse net users arraygatecat2022-02-271-1/+1
| | | | | | | | 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 predictDelaygatecat2021-12-192-7/+8
| | | | | | | | | | | | 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 Rothman2021-03-152-7/+18
| | | | | | | | | | | | | | | | | | | "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.

* Replace DelayInfo with DelayPair/DelayQuadgatecat2021-02-192-36/+3
| | | | | | | | | | | | | | | | | This replaces the arch-specific DelayInfo structure with new DelayPair (min/max only) and DelayQuad (min/max for both rise and fall) structures that form part of common code. This further reduces the amount of arch-specific code; and also provides useful data structures for timing analysis which will need to delay with pairs/quads of delays as it is improved. While there may be a small performance cost to arches that didn't separate the rise/fall cases (arches that aren't currently separating the min/max cases just need to be fixed...) in DelayInfo, my expectation is that inlining will mean this doesn't make much difference.

* Remove isValidBelForCellgatecat2021-02-163-12/+1
| | | | | | | | | | | | | | | | | This Arch API dates from when we were first working out how to implement placement validity checking, and in practice is little used by the core parts of placer1/HeAP and the Arch implementation involves a lot of duplication with isBelLocationValid. In the short term; placement validity checking is better served by the combination of checkBelAvail and isValidBelForCellType before placement; followed by isBelLocationValid after placement (potentially after moving/swapping multiple cells). Longer term, removing this API makes things a bit cleaner for a new validity checking API. Signed-off-by: gatecat <gatecat@ds0.me>
