chase-cps
Python interface to CHASE (Contract-based Heterogeneous Analysis and Systems Exploration), a framework for requirement capture, formalization, and validation of cyber-physical systems with assume-guarantee contracts.
The package contains the CHASE core library (contract representation and algebra) and a common interface to model checkers and synthesis tools.
from chase_cps import Contract, refines
spec = Contract.from_strings(inputs=["req"], outputs=["grant"],
assumptions=["G F !req"],
guarantees=["G (req -> F grant)"], name="Spec")
impl = Contract.from_strings(inputs=["req"], outputs=["grant"],
guarantees=["G (req -> X grant)"], name="Impl")
result = refines(impl, spec)
print(result.status) # valid, or invalid with a counterexample trace
The operations have the names of the commands of logics_tool, in three
layers:
- Contracts and their algebra (
chase_cps.contract). A contractchas the methodscompose,conjoin,disjoin,merge,divide(quotient),separate,imply,coimply,invert(reciprocal),assume,ensure,saturate, andsimplify, which return new contracts. They hold for any assume-guarantee contracts. - Checks (
chase_cps.checks,chase_cps.logic). The checks on contracts arerefines,verify(A & G satisfiable, which impliesis_compatibleandis_consistent),implements(a component satisfies the contract),accepts,is_receptive, andremove_redundant; the components and environments can be LTL formulas or state machines (Model: SMV, JSON, or a synthesized controller). They reduce to queries on formulas:implies(validity),is_satisfiable(satisfiability of a formula), andunsat_core. Acontextgives formulas that every behavior satisfies. - GR(1) synthesis (
chase_cps.gr1):is_realizable,synthesize,unrealizable_core,is_well_separated, andis_vacuous(vacuity in synthesis), for contracts in the GR(1) fragment of LTL.remove_redundant(c, synth=True)drops the terms that are redundant in the GR(1) game, before synthesis.
All the names are also in chase_cps. load_spec and parse_spec read the
contracts of a specification written in the logics language of CHASE, and
to_spec writes one.
Installation
$> pip install chase-cps
Wheels are available for Python 3.10 to 3.15 on Linux (x86_64 and aarch64, glibc 2.28 or later) and macOS 11 or later (arm64 and x86_64). Windows is not supported: use WSL or the CHASE Docker image.
Requirements
The package contains the CHASE library. The checks call external tools, which are not installed with the package:
- nuXmv for the checks (layer 2) and
remove_redundant. nuXmv is free for academic and non-commercial use. - slugs for the other analyses of GR(1) synthesis (layer 3).
The command chase-cps install downloads nuXmv from its site, and builds
slugs from its sources, into ~/.chase:
$> chase-cps install nuxmv --accept-license # Linux x86_64, macOS arm64
$> chase-cps install slugs # needs a C++ compiler, make, and Boost
On macOS, nuXmv needs the libraries of Homebrew (brew install libxml2 gmp libedit). On Linux it needs libxml2 and libedit2, and the C++ library of
GCC 13 or later (Ubuntu 24.04, Debian 13, Fedora 39, or newer);
chase-cps install says what is missing.
The tools can also be installed by hand: they are looked up in the PATH
and in ~/.chase/bin, or given with the environment variables CHASE_NUXMV
and CHASE_SLUGS. The command
$> chase-cps doctor
shows the tools found and how to install the missing ones.
Where nuXmv cannot be used (e.g. for commercial purposes), the checks run
with NuSMV (LGPL) instead: chase-cps install nusmv installs it on
Linux x86_64, or set CHASE_NUSMV.
Command line
chase-cps check checks the contracts of a specification written in the
logics language of CHASE, or of a JSON file, and prints the counterexamples:
$> chase-cps check specs.ltl # verify every contract
$> chase-cps check specs.ltl --refines Joint1+Joint2 Joints # composition refines Joints
$> chase-cps check specs.ltl --realizable Joint1 --json
$> chase-cps check specs.ltl --implements joint1.smv Joint1 --receptive joint1.smv Joint1
The exit status is 0 when every check passes, and 1 when a check fails.
The source code and the installation instructions are in the chase repository.
