Detailed help

Punf command line options

Usage:
     punf [-h]
or
     punf [options] [-f=]filename

Options (may be given in any order):

-h     Help.

-#     Using non-local configuration as cut-off correspondents.
         The current implementation is VERY INEFFICIENT.
         This option is not currently supported in the LTL mode.
-$n    Switch to SAT solver n (0-1).
         If n=0 then zChaff is used.
         If n=1 then MiniSAT is used (default).
-@[n]  Using ordering n (0-4).
         Specifies the ordering on configurations of the unfolding.
         If n is not specified or -@ is not used then the default
         value n=3 (for prefixes) or n=4 (for merged processes) is used.
         If n=0 then the set inclusion is used.
         If n=1 then the McMillan's order is used.
         If n=2 then the size-lexicographical order is used.
         If n=3 then the total Esparza/Roemer/Vogler (ERV) order is used.
         If n=4 then the total order with an efficient SAT encoding is used.
       Only the ERV order is currently supported in the LTL mode.
-!     Do not optimize preset trees (cheap optimization is performed anyway).
       (Ignored if -M is specified.)
-c     Do not store cut-off events (except the successful terminals in
       the LTL mode).
-d     When unfolding an STG, allow dummy cut-off events.
       If this option is not specified, a dummy event e can only be
       declared cut-off if its corresponding configuration C is a
       subset of [e], and [e]\C contains only dummies.
       This option has effect only when unfolding an STG.
       It is automatically specified if the STG contains only dummy signals.
       (Currently ignored if -M is specified.)
[-f=]filename
       Specifies the input file. It must be in either FORMAT_N or
       FORMAT_N2 format (produced by the PEP tool). Alternatively,
       it must have the suffix `.g' and be in the STG format;
       then an STG unfolding prefix (which may differ
       from the underlying Petri net's unfolding prefix) is produced.
       Aa an experimental feature, high-level nets are supported.
       For now, only strictly safe nets are allowed, and there are
       some further restrictions, described in the manual.
-L     LTL mode.
       The input net must be a product of Buechi automaton and a system.
-m[=filename]
       Specifies the name of the resulting file, whose extension also
       specifies the format. It can be either the legacy *.mci format
       for prefixes, the legacy *.mp format for merged processes (if -M
       is specified), or the new PNML-based *.pnml or *.pnml.gz format.
       If this option is not specified then the filename for the result
       is obtained by removing from the input filename the suffix `.ll_net',
       `.g' or `.hl_net' (if present), and appending the suffix `.pnml.gz',
       and the resulting prefix or merged process is stored in the new
       PNML-based format. If the filename is not specified (i.e. just -m
       is given) then no output file is created.
-N=n   Specifies the number of working threads (by default, it is equal
       to the number of processors). (Currently ignored if -M is specified.)

PComp command line options

Usage:
    pcomp [options] [@]file...

 The files in the command line are interpreted as STG files, except
 when prefixed with `@', in which case the file should contain a
 list of STG files, one per line (useful for avoiding the shell
 restriction on the length of the command line when composing many
 STGs). All the STGs, both in the command line and in the `@'-prefixed
 files, are used for composition.

 * The output signals of the STGs must be disjoint (this constraint
   can be waived with the -o option), and their union comprises
   the output signals of the composition. On the other hand, the input
   signals can be shared by several STGs, and also an output signal of
   some STG can be an input signal of zero or more other STGs.
 * The internal and dummy signals, as well as places, are renamed
   whenever necessary to avoid name clashes.
 * The composed STG is simplified by removing duplicate places.
 * 2-phase, 4-phase and mixed-phase STGs can be liberally composed.

Options:
  -d  Convert the common interface signals into dummy signals
      (useful for composing handshake components).
  -f[file]
      Stores the composed STG in file rather than standard output.
      The extension (.g, .pnml, or .pnml.gz) determines the format.
      If file is not specified, pcomp.g is used.
  -h  Print this help message and exit.
  -i  Convert the common interface signals into internal signals
      (useful for composing handshake components).
  -l[file]
      If the file name is not provided then `pcomp.xml.gz' is used.
      If the file name ends with `.xml' or `xml.gz' then the
      correspondence between the places and transitions of the
      component STGs and those of the composed STG is stored.
      Otherwise place names of the composed STG are stored, so that
      the i-th line corresponds to the places of i-th component STG
      Note that the same place can occur in several lines - this
      happens when some duplicate place is removed, and some
      equivalent place is listed instead.
  -o  Allow the STGs to share outputs.
  -p  Before doing the parallel composition, remove places whose
      presets do not contain dummy transitions and whose postsets
      contain only shared input signals on which the labelling is
      injective. This transformation results in a composed STG with
      fewer places, which has bisimilar behaviour provided the
      composition is free from computational interference. This
      option is incompatible with -o.
  -r  Rename all dummy transitions, so that their names do not
      contain '+', '-', or '/'. (Needed for compatibility with tools
      that do not allow dummy transitions to have signs, e.g. Petrify.)
  -u  Keep unused signal transition phases. This option considers
      e.g. x+ and x- as independent transition labels. By default,
      if two STGs are composed, and one of them has x+ but no x-,
      while the other has x- but no x+, the composed STG will have
      no transitions labelled by either x+ or x-. However, if this
      option is specified, both labels will occur in the composed STG.
