README


This directory contains Verific bindings for Yosys.
See http://www.verific.com/ for details.


Verific Features that should be enabled in your Verific library
===============================================================

database/DBCompileFlags.h:
	DB_PRESERVE_INITIAL_VALUE


Testing Verific+Yosys+SymbiYosys for formal verification
========================================================

Install Yosys+Verific, SymbiYosys, and Yices2. Install instructions:
http://symbiyosys.readthedocs.io/en/latest/quickstart.html#installing

Then run in the following command in this directory:

	sby -f example.sby

This will generate approximately one page of text outpout. The last lines
should be something like this:

	SBY [example] summary: Elapsed clock time [H:MM:SS (secs)]: 0:00:00 (0)
	SBY [example] summary: Elapsed process time [H:MM:SS (secs)]: 0:00:00 (0)
	SBY [example] summary: engine_0 (smtbmc yices) returned PASS for basecase
	SBY [example] summary: engine_0 (smtbmc yices) returned PASS for induction
	SBY [example] summary: successful proof by k-induction.
	SBY [example] DONE (PASS, rc=0)
