* Initial lookahead for FPGA interchange.Keith Rothman2021-03-2315-13/+2689
| | | | | | | | | Currently the lookahead is disabled by default because of the time to compute and RAM usage. However it does appear to work reasonably well in testing. Further effort is required to lower RAM usage after initial computation, and explore trade-off for cheaper time to compute. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| * Correct some bugs in writing of physical netlist w.r.t. site sources.Keith Rothman2021-03-221-11/+93
| | | | | | | | | | | | | | Local site sources should have their driving BEL pin included in the net so that the site wire is driven by an output BEL pin. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| | | | | | | | | | | | | | | | | | | | | The new site router should be robust to most situations, and isn't significantly slower with the use of caching. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "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.
