| * HeAP: Skip high-strength cells in both cell loops.Adam Greig2021-04-121-0/+4
| | | | | | | | | | | | Previously only the first loop skipped cells with high belStrength, but they can't be processed by the second loop either, so skip them there too.

* Fix bug in router2 where router may give up too early.Keith Rothman2021-04-061-1/+13
| | | | | | | | | | Was introduced in #612. The logic before was intended to prevent the router from terminating early when not using a bounding box, but the fix in #612 simply removed that, meaning that the router might terminate early incorrectly. The solution here is to only use the toexplore hysteric once a solution is found. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

|/ | | | | | | | This is important for distiguishing valid pseudo pips in the FPGA interchange arch. This also avoids a double or triple lookup of pip->net map. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

|\ | | | | Split nextpnr.h to allow for linear inclusion.
| * Split nextpnr.h to allow for linear inclusion.Keith Rothman2021-03-1530-2395/+3104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "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.

* Only depend on Abseil in threaded builds.whitequark2021-03-101-0/+6
| | | | | | Abseil has a hard dependency on threads (not just in the build system but in many places in the base libraries), so there is no way to use it on WASI at the moment.
