1dc1164dce CMake: rewrite chipdb handling from ground up. 2020-06-25 14:03:37 +00:00
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.

Alter MULT18X18D timing db based on register config 
If the REG_INPUTA_CLK and REG_INPUTB_CLK values are set, then we should
use the faster setup/hold timings for the 18x8 multiplier.
Similarly, check the value of REG_OUTPUT_CLK for whether or not to use
faster timings for the output.

This is based on how I currently understand the registers to work - if
anyone knows the actual rules for when each timing applies please do
chime in to correct this implementation if necessary.

Along the same lines, this PR does not address the case when the
pipeline registers are enabled, since it is not clear to me how exactly
that affects the timing.
