David Shah b18ea204c2 Remove wire alias API 
It has not actually been implemented in any router for over 2.5 years and causes nothing more than confusion. It can always be added back if it forms part of a future solution; possibly as part of a more general database structure rethink.

Add option to print critical path source code 
In order to make debugging the critical path easier, add an option that
will log the location each net was defined, if known.
If the file that contains the definition is known, and is readable, also
print the part of the source HDL responsible for the signal definition.

Port nextpnr-{ice40,ecp5} to WASI
 2020-05-24 14:23:35 +01:00
whitequark e7bb04769d Port nextpnr-{ice40,ecp5} to WASI. 
This involves very few changes, all typical to WASM ports:
  * WASM doesn't currently support threads or atomics so those are
    disabled.
  * WASM doesn't currently support exceptions so the exception
    machinery is stubbed out.
  * WASM doesn't (and can't) have mmap(), so an emulation library is
    used. That library currently doesn't support MAP_SHARED flags,
    so MAP_PRIVATE is used instead.

There is also an update to bring ECP5 bbasm CMake rules to parity
with iCE40 ones, since although it is possible to embed chipdb into
nextpnr on WASM, a 200 MB WASM file has very few practical uses.

The README is not updated and there is no included toolchain file
because at the moment it's not possible to build nextpnr with
upstream boost and wasi-libc. Boost requires a patch (merged, will
be available in boost 1.74.0), wasi-libc requires a few unmerged
patches.

Sylvain Munaut 4a9981ee77 pycontainers: Properly handle KeyErrors 
We raise a C++ exception to abort the rest of the execution of
the function.

At the same time we standardize on using a throw runtime error as the
method to avoid warning when not returning values. (some places
used this throw and some other used std::terminate)

Fixes #403

David Shah 7142db28a8 HeAP: Make HeAP placer optional 
A CMake option 'BUILD_HEAP' (default on) configures building of the
HeAP placer and the associated Eigen3 dependency.

Default for the iCE40 is SA placer, with --heap-placer to use HeAP

Default for the ECP5 is HeAP placer, as SA placer can take 1hr+ for
large ECP5 designs and HeAP tends to give better QoR. --sa-placer can
be used to use SA instead, and auto-fallback to SA if HeAP not built.
