*	gowin: add support for wide LUTs.	YRabbit	2021-10-07	1	-0/+1
\| \| \| \| \| \| \| \| \|	* A hardwired MUX within each logical cell is used. * The delay is equal 0. * No user placement constraints. * The output route contains dummy PIPs. They are ignored by gowin_pack, but it may be worth removing them. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

*	Split nextpnr.h to allow for linear inclusion.	Keith Rothman	2021-03-15	1	-3/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	"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/DelayQuad	gatecat	2021-02-19	1	-27/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.
