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.

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.
