It is a generic, low-level formalism that can describe any kind of system using variables and initial/transition expressions. The project includes: + +* Classes to represent STSs. +* A domain specific language (DSL) to parse STSs from a textual representation. +* A frontend that can parse systems described in the [AIGER](http://fmv.jku.at/aiger/) (And-Inverter Graph) format and represent them using STSs. + +### Related projects + +* [`sts-analysis`](../sts-analysis/README.md): STS specific analysis modules enabling the algorithms to operate on them. +* [`sts-cli`](../sts-cli/README.md): An executable tool (command line) for running analyses on STSs. + +## STS Formalism + +STSs consist of + +* Variables, +* an initial expression describing the initial states, +* a transition expression (over the variables and their primed version) describing the transition relation, where the plain variables correspond to the actual state, while the primed variables correspond to the next state, and +* a property expression. + +Algorithms are usually interested in proving that the property holds for every reachable state (safety property). + +### Textual Representation (DSL) + +An example STS realizing a counter: + +``` +specification Counter { + property P : { + var x : integer + initial x = 0 + transition if x < 10 then x' = x + 1 or x' = 0 else x' = 0 + } models G(x <= 10) +} +``` + +See _src/test/resources_ for more examples and _src/main/antlr_ for the full grammar. + +### AIGER Frontend + +The AIGER frontend can parse _aag_ (version 1.7) files into STSs. Some utilities are also available, such as visualization and reductions.

executable tool (command line) for running analyses on XSTSs. +The `xsts-cli` project is an executable (command line) tool for running CEGAR-based analyses on XSTSs. +For more information about the XSTS formalism and its supported language elements, take a look at the [`xsts`](../xsts/README.md) project. ### Related projects * [`xsts`](../xsts/README.md): Classes to represent XSTSs and a domain specific language (DSL) to parse XSTSs from a textual representation. * [`xsts-analysis`](../xsts-analysis/README.md): XSTS specific analysis modules enabling the algorithms to operate on them. -## Tool +## Using the tool -First, [build](../../doc/Build.md) the projects. -The runnable jar file will appear under _build/libs/_ with the name _theta-xsts-cli-\-all.jar_. -You can simply rename it to _theta-xsts-cli.jar_. -The tool also requires the [Z3 SMT solver](../../doc/Build.md). +1. First, get the tool. + * The easiest way is to download a [pre-built release](https://github.com/ftsrg/theta/releases). + * You can also [build](../../doc/Build.md) the tool yourself. The runnable jar file will appear under _build/libs/_ with the name _theta-xsts-cli-\-all.jar_, you can simply rename it to _theta-xsts-cli.jar_. + * Alternatively, you can use our docker image (see below). +2. Running the tool requires Java (JRE) 11. +3. The tool also requires the [Z3 SMT solver libraries](../../doc/Build.md) to be available on `PATH`. +4. The tool can be executed with `java -jar theta-xsts-cli.jar [ARGUMENTS]`. + * If no arguments are given, a help screen is displayed about the arguments and their possible values. + More information can also be found below. + * For example `java -jar theta-xsts-cli.jar --model crossroad.xsts --property "x>1" --loglevel INFO` runs the default analysis with logging on the `crossroad.xsts` model file with the property `x>1`. -The tool can be run with `java -jar theta-xsts-cli.jar [arguments]`. -If no arguments are given, a help screen is displayed about the arguments and their possible values. -For example `java -jar theta-xsts-cli.jar --model trafficlight.xsts --property red_green.prop` runs the default analysis with the `red_green.prop` property on the `trafficlight.xsts` input file. \ No newline at end of file +### Docker + +A Dockerfile is also available under the _docker_ directory in the root of the repository. +The image can be built using the following command (from the root of the repository): +``` +docker build -t theta-xsts-cli -f docker/theta-xsts-cli.Dockerfile . +``` + +The script `run-theta-xsts-cli.sh` can be used for running the containerized version on models residing on the host: +``` +./docker/run-theta-xsts-cli.sh crossroad.xsts --property "x>1" [OTHER ARGUMENTS] +``` +Note that the model must be given as the first positional argument (without `--model`). + +## Arguments + +All arguments are optional, except `--model` and `--property`. + +* `--model`: Path of the input XSTS model (mandatory). +* `--property`: Input property as a string or a file (*.prop) (mandatory). +* `--cex`: Output file where the counterexample is written (if the result is unsafe). If the argument is not given (default) the counterexample is not printed. Use `CON` (Windows) or `/dev/stdout` (Linux) as argument to print to the standard output. +* `--loglevel`: Detailedness of logging. + * Possible values (from the least to the most detailed): `RESULT`, `MAINSTEP`, `SUBSTEP` (default), `INFO`, `DETAIL`, `VERBOSE`. +* `--domain`: Domain of the abstraction, possible values: + * `PRED_CART`: Cartesian predicate abstraction (default). + * `PRED_BOOL`: Boolean predicate abstraction. + * `PRED_SPLIT`: Boolean predicate abstraction with splitting. + * `EXPL`: Explicit-value abstraction. + * `PROD`: Product abstraction with predicate and explicit-value abstraction. + * _Remark: Predicate abstraction tracks logical formulas instead of concrete values of variables, which can be efficient for variables with large (or infinite) domain. + Explicit-values keep track of a subset of system variables, which can be efficient if variables are mostly deterministic or have a small domain. + Cartesian predicate abstraction only uses conjunctions (more efficient) while Boolean allows arbitrary formulas (more expressive). + Boolean predicate abstraction often gives predicates in a disjunctive normal form (DNF). + In `PRED_BOOL` this DNF formula is treated as a single state, while in `PRED_SPLIT` each operand of the disjunction is a separate state._ + * _Remark: It is recommended to try Cartesian first and fall back to Boolean if there is no refinement progress (seemingly infinite iterations with the same counterexample). + Splitting rarely resulted in better performance._ + * _More information on the abstract domains can be found in [our JAR paper](https://link.springer.com/content/pdf/10.1007%2Fs10817-019-09535-x.pdf), Sections 2.2.1 and 3.1.3._ +* `--initprec`: Initial precision of the abstraction. + * `EMPTY`: Start with an empty initial precision (default). + * `PROP`: Track all variables of the property by default if `--domain` is `EXPL`.
