Marcelina Kościelnicka 18ad56ef41 Add dffunmap pass.
To be used with backends that cannot deal with fancy FF types (like blif
or smt).

Marcelina Kościelnicka 6cd135a5eb opt_expr: Remove -clkinv option, make it the default.
Adds -noclkinv option just in case the old behavior was actually useful
to someone.

Marcelina Kościelnicka cf60699884 synth_ice40: Use opt_dff.
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

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"

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.

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.
