Marcelina Kościelnicka 1c903d3e47 sim: Add wide port support. 2021-05-25 02:57:32 +02:00
Marcelina Kościelnicka c4cc888b2c kernel/rtlil: Extract some helpers for checking memory cell types. 
There will soon be more (versioned) memory cells, so handle passes that
only care if a cell is memory-related by a simple helper call instead of
a hardcoded list.

qbfsat: Add `-solver-option` option. 2020-07-20 21:54:56 +00:00
Marcelina Kościelnicka 03e28f7ab4 clk2fflogic: Consistently treat async control signals as negative hold. 
This fixes some dfflegalize equivalence checks, and breaks others — and
I strongly suspect the others are due to bad support for multiple
async inputs in `proc` (in particular, lack of proper support for
dlatchsr and sketchy circuits on dffsr control inputs).

qbfsat: Fix name-based hole specialization. 
Look for unique connections in the containing module with the $anyconst port Y SigBit on the RHS and use those. If no such connection is found, fall back to using the name of the $anyconst port Y SigBit.

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.

smtbmc and qbfsat: Add timeout option to set solver timeouts for Z3, Yices, and CVC4. 2020-05-25 20:39:30 +00:00

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.
