qbfsat: Avoid instantiating `AttrObject`s directly. 
Co-Authored-By: Claire Wolf <claire@symbioticeda.com>

qbfsat: Simplify solution format and replace `SigBit::str()` with `log_signal()`. 
Co-Authored-By: Claire Wolf <claire@symbioticeda.com>

qbfsat: Fixes three bugs. 
1. Infinite loop in the optimization procedure when the first solution found while maximizing is at zero.
2. A signed-ness issue when maximizing.
3. Erroneously entering bisection mode with no wire to optimize.

qbfsat: Use bit precise mapping for hole value wires and a more robust hole spec for writing to and specializing from a solution file. 2020-06-21 02:16:11 +00:00

smtbmc and qbfsat: Add timeout option to set solver timeouts for Z3, Yices, and CVC4. 2020-05-25 20:39:30 +00:00
Alberto Gonzalez f9eef5e3f7
qbfsat: Add support for CVC4. 2020-05-25 20:39:03 +00:00
Alberto Gonzalez 903456c267
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.

qbfsat: Remove cruft inadvertently left untouched in commit 86fc49a9d6. 2020-05-23 00:53:09 +00:00
Alberto Gonzalez aea0fd5ed4
qbfsat: Add bisection mode and make it the default. 
Also adds `-nooptimize` and reorganizes `qbfsat.cc` a bit.
 2020-05-23 00:53:09 +00:00
whitequark b43c282e4e Add WASI platform support. 
This includes the following significant changes:
  * 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.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
