The LTL2BA software was written by Denis Oddoux and modified by Paul

Part of the code included is issued from the SPIN software Version 3.4.1
|
|
The SPIN software is written by Gerard J. Holzmann, originally as part
|
|
of ``Design and Validation of Protocols,'' ISBN 0-13-539925-4,
|
|
1991, Prentice Hall, Englewood Cliffs, NJ, 07632
|
|
Here are the files that contain some code from Spin v3.4.1 :
|
|
|
|
cache.c (originally tl_cache.c)
|
|
lex.c ( tl_lex.c )
|
|
ltl2ba.h ( tl.h )
|
|
main.c ( tl_main.c )
|
|
mem.c ( tl_mem.c )
|
|
parse.c ( tl_parse.c)
|
|
rewrt.c ( tl_rewrt.c)
|
|
trans.c ( tl_trans.c)
|
|
|
|
2. COMPILING
|
|
|
|
open the archive :
|
|
> gunzip ltl2ba-1.1.tar.gz
|
|
> tar xf ltl2ba-1.1.tar
|
|
> cd ltl2ba-1.1
|
|
|
|
compile the program
|
|
> make
|
|
|
|
3. EXECUTING
|
|
|
|
run the program
|
|
> ./ltl2ba -f "formula"
|
|
|
|
The formula is an LTL formula, and may contain propositional symbols,
|
|
boolean operators, temporal operators, and parentheses.
|
|
The syntax used is the one used in the 'Spin' model-checker
|
|
|
|
Propositonal Symbols:
|
|
true, false
|
|
any lowercase string
|
|
|
|
Boolean operators:
|
|
! (negation)
|
|
-> (implication)
|
|
<-> (equivalence)
|
|
&& (and)
|
|
|| (or)
|
|
|
|
Temporal operators:
|
|
[] (always)
|
|
<> (eventually)
|
|
U (until)
|
|
V (release)
|
|
X (next)
|
|
|
|
Use spaces between any symbols.
|
|
|
|
The result is a never claim in Promela that can be given to the
|
|
Spin model checker to verify properties on a system.
|
|
|
|
run the command
|
|
> ./ltl2ba
|
|
to see the possible options for executing the program

4. CHANGES IN VERSION 1.1
|
|
|
|
- fixing a bug in the way sets were used for strongly connected components. Thanks to Joachim Klein (klein@tcs.inf.tu-dresden.de) who found the bug and proposed a patch to fix it.
|
|
- fixing a bug in the simplification with strongly connected components for the generalized Büchi automaton.
|
|
- improving the simplification with strongly connected components for the generalized Büchi automaton.
|
|
- using getrusage to compute running times for the statistics
|
|
- some other minor updates.
