* Split nextpnr.h to allow for linear inclusion.Keith Rothman2021-03-151-0/+4
| | | | | | | | | | | | | | | | | | | "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.

* ecp5: Use snake case for arch-specific functionsD. Shah2021-02-031-1/+1
| | | | | | | This makes the difference clearer between the general arch API that everyone must implement; and helper functions specific to one arch. Signed-off-by: D. Shah <dave@ds0.me>

* Fix assertion failure on invalid LOCATE input.Gary Wong2020-04-051-0/+2
| | | | | | | | | | | | | | Trying to parse this invalid LPF syntax: LOCATE COMP "a" SITE "A1" IOBUF PORT "a" IO_TYPE=LVCMOS33; (note missing semicolon on first line) gives an assertion failure in strip_quotes, because the fifth token is scanned as "A1"IOBUF (without a trailing quote). Avoid the problem by detecting extraneous input and issuing a more specific error.
