* [interchange] Prevent site router from generating incorrect LUTs.Keith Rothman2021-04-061-2/+4
| | | | | | | | | The previous logic tied LUT input pins to VCC if a wire was unplacable. This missed a case where the net was present to the input of the LUT, but a wire was still not legal. This case is now prevented by tying the output of the LUT to an unused net. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

* Split nextpnr.h to allow for linear inclusion.Keith Rothman2021-03-151-6/+8
| | | | | | | | | | | | | | | | | | | "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.
