Merge pull request #447 from whitequark/wasi 
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.

5e763b1afc
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.

ec1eea9990 Fix assertion failure on invalid LOCATE input. 
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.

8cc6a2fae5 Remove comment about the USRMCLK primitive being untested. 
Tested and verified working: the trivial configuration:

    module USRMCLK( USRMCLKI, USRMCLKTS );
        input USRMCLKI, USRMCLKTS;
    endmodule

    module top( input clk );
        reg[ 24:0 ] count = 0;

        always @( posedge clk ) begin
            count <= count + 1'b1;
        end

        USRMCLK mspi( .USRMCLKI( count[ 20 ] ), .USRMCLKTS( count[ 24 ] ) );
    endmodule

produces the expected output (toggling at high frequency, toggling
tri-state at lower frequency) on an LFE5U-85 when fed with an appropriate
clock.  See https://bayimg.com/AAnNKAAGO for an example.  The top
(magenta) trace is the MCLK line.

eba6ea53f8 More adjustments to .bba file locations 
Follows PM discussion with Marcus Comstedt.
Extend changes in .bba file location (made in commit b6a7b60) to ice40 and MSVC cases,
  so all cases become compatible with read-only access to git tree.
Only known down-side is inefficiency when building out-of-tree for multiple architectures;
  people following that use case should consider using PREGENERATED_BBA_PATH.
It would be nice if there were less copy-paste in MSVC vs. non-MSVC content in family.cmake,
  but that would have to be addressed by someone more skilled in Cmake and MSVC.
