HeAP: Skip high-strength cells in both cell loops
|
| |
| |
| |
| |
| |
| | |
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.

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.

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.

Split nextpnr.h to allow for linear inclusion.

"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.

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.

Add absl::flat_hash_map.

This lowers the CPU cost of using the flat wire map in router2, and should
use less memory as well.
