Merge pull request #2306 from YosysHQ/mwk/equiv_induct-undef 
equiv_induct: Fix up assumption for $equiv cells in -undef mode.

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.

Marcelina Kościelnicka 85a1bb17ed satgen: Move importCell out of the header. 
This function has no hope of ever getting inlined anyway, and it speeds
up yosys compile time by 7%.
