Merge pull request #2306 from YosysHQ/mwk/equiv_induct-undef 
equiv_induct: Fix up assumption for $equiv cells in -undef mode.
 2020-07-28 12:56:22 +02:00
Marcelina Kościelnicka a1a0abf52a equiv_induct: Fix up assumption for $equiv cells in -undef mode. 
Before this fix, equiv_induct only assumed that one of the following is
true:

- defined value of A is equal to defined value of B
- A is undefined

This lets through valuations where A is defined, B is undefined, and
the defined (meaningless) value of B happens to match the defined value
of A.  Instead, tighten this up to OR of the following:

- defined value of A is equal to defined value of B, and B is not
  undefined
- A is undefined

Keith Rothman 819f1d8c20 Remove EXPLICIT_CARRY logic. 
The symbiflow-arch-defs tool chain no longer needs the EXPLICIT_CARRY
within yosys itself.

Marcelina Kościelnicka dc07ae9677 techmap: Add _TECHMAP_CELLNAME_ special parameter. 
This parameter will resolve to the name of the cell being mapped.  The
first user of this parameter will be synth_intel_alm's Quartus output,
which requires a unique (and preferably descriptive) name passed as
a cell parameter for the memory cells.

Merge pull request #2215 from boqwxp/qbfsat-solver-options 
qbfsat, smt2, smtio: Add `-solver-option` to allow specifying SMT-LIBv2 `(set-option ...)` commands
 2020-07-21 14:43:33 +02:00
Alberto Gonzalez 42fb75c570
smtio: Emit `mode: start` options before `set-logic` command and any other options after it. 
Refer to the SMT-LIB specification, section 4.1.7.  According to the spec, some options can only be specified in `start` mode.  Once the solver sees `set-logic`, it moves to `assert` mode.

This function has no hope of ever getting inlined anyway, and it speeds
up yosys compile time by 7%.

whitequark 128522f173 verilog_backend: in non-SV mode, add a trigger for `always @*`. 
This commit only affects translation of RTLIL processes (for which
there is limited support).

Due to the event-driven nature of Verilog, processes like

    reg x;
    always @*
        x <= 1;

may never execute. This can be fixed in SystemVerilog code by using
`always_comb` instead of `always @*`, but in Verilog-2001 the options
are limited. This commit implements the following workaround:

    reg init = 0;
    reg x;
    always @* begin
        if (init) begin end
        x <= 1;
    end

Fixes #2271.
