Jannis Harder 7a0c37b62d Initial dft_tag implementation 
This is still missing a mode to rewrite $overwrite_tag and $original_tag
by injecting $set_tag and $get_tag in the right places. It's also
missing bit-precise propagation models for shifts and arithmetic and
requires the design to be flattened.

Merge pull request #2019 from boqwxp/glift 
Add `glift` command for creating gate-level information flow tracking models and optimization problems
 2022-02-11 15:51:24 +01:00
Marcelina Kościelnicka 0aad88a2fb Add clean_zerowidth pass, use it for Verilog output. 
This should remove instances of zero-width sigspecs in the netlist,
avoiding problems in the Verilog backend with emitting them.

See #3103.

whitequark b43c282e4e Add WASI platform support. 
This includes the following significant changes:
  * Patching ezsat and minisat to disable resource limiting code
    on WASM/WASI, since the POSIX functions they use are unavailable.
  * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
    does not support spawning subprocesses (i.e. Emscripten or WASI).
    This definition hides the definition of `run_command()`.
  * Adding a new Makefile flag, DISABLE_SPAWN, present in the same
    condition. This flag disables all passes that require spawning
    subprocesses for their function.

whitequark a342d6db49 bugpoint: new pass. 
A typical use of `bugpoint` would involve a script with a pass under
test, e.g.:

    flowmap -relax -optarea 100

and would be invoked as:

    bugpoint -yosys ./yosys -script flowmap.ys -clean -cells

This replaces the current design with the minimal design that still
crashes the `flowmap.ys` script.

`bugpoint` can also be used to perform generic design minimization
using `select`, e.g. the following script:

    select i:* %x t:$_MUX_ %i -assert-max 0

would remove all parts of the design except for an unbroken path from
an input to an output port that goes through exactly one $_MUX_ cell.
(The condition is inverted.)
