NAME

       victor - attempts to discharge verification conditions using SMT solvers

SYNOPSIS

       victor [UNIT]

DESCRIPTION

       The  victor  command is a wrapper around ViCToR (vct) which simplifies its use. ViCToR translates SPARK verification conditions into SMTlib
       and feeds them to an SMT solver. SPARK ships with one such SMT solver, alt-ergo, but it is possible to use others solvers such as cvc3.

       The intended use of victor is to discharge true VCs left over by the Simplifier and not replace the Simplifier. Please also note that  ViC-
       ToR is considered to be an experimental feature at the moment.

       This manual page only summarises the victor command-line flags, please refer to the full VictorWrapper manual for further information.

OPTIONS

       These options do not quite follow the usual GNU command line syntax as options start with a single dash instead of the usual two.

       -h, -help
	      Shows command-line help.

       -t=SECONDS
	      Time-out the SMT solver after this many seconds (by default 5) using ulimit. To disable time-out specify 0.

       -m=MEGABYTES
	      Limit the SMT solver to this many MiB of virtual memory (by default no limit) using ulimit.

       -v     Ignore  the presence of any siv files and process vcg files only. By default, given a UNIT such as foo, victor will first attempt to
	      process foo.siv and then fall back to foo.vcg.

       -plain Plain mode -- supress timings and versions.

       -solver=SOLVER
	      Specifies an alternative SMT solver. By default we use alt-ergo. Can be one of alt-ergo, cvc3, yices or z3. The alt-ergo	solver	is
	      distributed with SPARK. The cvc3 solver is part of Debian. The yices and z3 solvers are proprietary.
