Alberto Gonzalez 91c20fca72
glift: Add `-simple-cost-model` option 
Rather than assigning specific weights to specific versions of taint tracking logic and summing the weights of all GLIFT cells, sum the following values for each GLIFT cell:
  - 0 if the associated hole/$anyconst cell value is non-zero, i.e. reduced-precision taint tracking logic is chosen at this cell
  - 1 if the associated hole/$anyconst cell value is zero, i.e. the full-precision taint tracking logic is chosen at this cell

This simplified cost modeling reduces the potential for the QBF-SAT solver to minimize taint tracking logic area but significantly simplifies the QBF-SAT problem.

Marcelina Kościelnicka b0bee396a8 Add new builtin FF types 
The new types include:

- FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`)
- FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`)
- FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`)
- FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`)
- FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`)
- latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`)

The new FF types are not actually used anywhere yet (this is left
for future commits).

whitequark a1814b732f flatten: make hygienic. 
Before this commit, `flatten` matched the template objects with
the newly created objects solely by their name. Because of this,
it could be confused by code such as:

    module bar();
      $dff a();
    endmodule

    module foo();
      bar b();
      $dff \b.a ();
    endmodule

After this commit, `flatten` avoids every possible case of name
collision.

Fixes #2106.

Marcelina Kościelnicka 28b9f49c94 fsm_extract: avoid calling log_signal to determine wire name 
log_signal can result in a string with spaces (when bit selection is
involved), which breaks the rule of IdString not containing whitespace.
Instead, remove the sigspec from the name entirely — given that the
resulting wire will have no users, it will be removed later anyway,
so its name doesn't really matter.

whitequark 6268bdfe6f flatten: simplify. 
`flatten` cannot derive modules in most cases because that would just
yield processes, and it does not support `-autoproc`; in practice
`flatten` has to be preceded by a call to `hierarchy`, which makes
deriving unnecessary.

Add flooring division operator 
The $div and $mod cells use truncating division semantics (rounding
towards 0), as defined by e.g. Verilog. Another rounding mode, flooring
(rounding towards negative infinity), can be used in e.g. VHDL. The
new $divfloor cell provides this flooring division.

This commit also fixes the handling of $div in opt_expr, which was

Rupert Swarbrick d681c9df85 Pass some more args by reference in select.cc 
Before this patch, the code passed around std::string objects by
value. It's probably not a hot-spot, but it can't hurt to avoid the
copying.

Removing the copy and clean-up code means the resulting code is ~6.1kb
smaller when compiled with GCC 9.3 and standard settings.
 2020-05-27 09:42:23 +01:00
Rupert Swarbrick 061d1f0c07 Minor optimisations in select.cc's match_ids function 
- Pass a string argument by reference

  - Avoid multiple calls to IdString::str and IdString::c_str

  - Avoid combining checks for size > 0 and first char (C strings are
    null terminated, so foo[0] != '\0' implies that foo has positive
    length)
 2020-05-27 09:36:33 +01:00
Rupert Swarbrick 0d9beb5b2e Silence warning in select.cc 
With GCC 9.3, at least, compiling select.cc spits out a warning about
an implausible bound being passed to strncmp. This comes from inlining
IdString::compare(): it turns out that passing std::string::npos as a
bound to strncmp triggers it.

This patch replaces the compare call with a memcmp with the same
effect. The repeated calls to IdString::c_str are slightly
inefficient, but I'll address that in a follow-up commit.

misc: Add `printattrs` command. 2020-05-27 08:00:00 +00:00
Rupert Swarbrick 7746bba69a Simplify a modport check in hierarchy.cc 
This code originally comes from commit 458a940. When an interface is
used via a modport, code in genrtlil.cc sets '\\interface_type' and
'\\interface_modport' properties on the wire.

In hierarchy.cc, we pick up the modport name and add it to a dict
called modports_used_in_submodule (that maps connection source to
modport name).

Before this patch, the modport name is retrieved as a strpool and then
iterated over in an arbitrary order, discarding all entries but the
last. In practice, the pool will always have 0 or 1 entries because
the string used to construct it is a valid identifier, so doesn't
contain any pipe symbols.

This patch changes the code to retrieve the modport name as just a
string. This will have the same effect in practice, but may be a bit
less confusing!

The code also gets moved down closer to where the result is used,
which might be a bit more efficient since we won't always get as far
as the check.

The patch also removes some commented-out code, which I think was
intended to add some typechecking at some point, but was never
implemented. Since this dates back to October 2018, I think it makes
more sense to just take it out.

qbfsat: Add `-solver` option and allow choice of Z3 or Yices, making Yices the default. 
Ensures that "BV" is the logic whenever solving an exists-forall problem with Yices, moves the "(set-logic ...)" directive above any non-info line, sets the `ef-max-iters` parameter to a very high number when using Yices in exists-forall mode so as not to prematurely abandon difficult problems, and does not provide the incompatible "--incremental" Yices argument when in exists-forall mode.

  * 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 e0def9e4d9 memory_map: add -attr option, to respect inference attributes. 
Before this commit, memory_map (which is always a part of a synth
script) would always pick up any $mem cell that was not processed
by a preceding pass and lower it down to $dff/$mux cells.
This is undesirable for two reasons:
  * If there is an explicit inference attribute set on a $mem cell,
    e.g. (* ram_block *), then it is arguably incorrect to map such
    a memory to $dff/$mux cells.
  * If memory_map tries to lower a memory that was intended to
    be mapped to a large BRAM, it often takes extraordinarily long
    time to finish, produces an extremely large log file, and outputs
    an unusable design.

After this commit, properly invoked memory_map will not map any
memory that has an explicit inference attribute specified, solving
the first issue, and alleviating the second. The default behavior
is not changed.

Marcin Kościelnicki f68985f997 deminout: prevent any constant assignment from demoting to input 
Before this patch,

```
module top(inout io);
assign io = 1'bx;
endmodule
```

would have the `io` pin demoted to input (same happens for `1'bz`,
but not for `1'b0` or `1'b1`), resulting in check failures later on.

Part of fix for #1841.

Rupert Swarbrick 044ca9dde4 Add support for SystemVerilog-style `define to Verilog frontend 
This patch should support things like

  `define foo(a, b = 3, c)   a+b+c

  `foo(1, ,2)

which will evaluate to 1+3+2. It also spots mistakes like

  `foo(1)

(the 3rd argument doesn't have a default value, so a call site is
required to set it).

Most of the patch is a simple parser for the format in preproc.cc, but
I've also taken the opportunity to wrap up the "name -> definition"
map in a type, rather than use multiple std::map's.

Since this type needs to be visible to code that touches defines, I've
pulled it (and the frontend_verilog_preproc declaration) out into a
new file at frontends/verilog/preproc.h and included that where
necessary.

Finally, the patch adds a few tests in tests/various to check that we
are parsing everything correctly.
