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

Sahand Kashani 2c6cc27af1 Add firrtl backend support for generic parameters in blackbox components
Previous blackbox components were just emitted with their interface ports,
but their generic parameters were never emitted and it was therefore
impossible to customize them.

This commit adds support for blackbox generic parameters, though support
is only provided for INTEGER and STRING parameters. Other types of
parameters such as DOUBLEs, ..., would result in undefined behavior here.

This allows the emission of custom extmodule instances such as the following:

extmodule fourteennm_lcell_comb_<instName>:
  input cin: UInt<1>
  output combout: UInt<1>
  output cout: UInt<1>
  input dataa: UInt<1>
  input datab: UInt<1>
  input datac: UInt<1>
  input datad: UInt<1>
  input datae: UInt<1>
  input dataf: UInt<1>
  input datag: UInt<1>
  input datah: UInt<1>
  input sharein: UInt<1>
  output shareout: UInt<1>
  output sumout: UInt<1>
  defname = fourteennm_lcell_comb
  parameter extended_lut = "off"
  parameter lut_mask = "b0001001000010010000100100001001000010010000100100001001000010010"
  parameter shared_arith = "off"

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.
