electrod - Formal analysis for the Electrod formal specification language

Electrod is a model finder that takes as input a model expressed in a mixture of relational first-order logic (RFOL) over bounded domains and linear temporal logic (LTL) over an unbounded time horizon. Then it compiles the model to a problem for a solver (currently the NuSMV and nuXmv model-checkers). Electrod is mainly meant to be used as a backend for the Alloy Analyzer 6.

Installation instructions

Installation has essentially been tested on GNU/Linux and Mac OS X, but it can be built for Windows.

The easiest way to install Electrod is to rely on Opam, the OCaml package manager.

Once Opam is installed and initialized, clone this directory, cd into it and issue the following commands:

make setup
make release

which produces a self-contained executable electrod.exe in the directory.

Developement instructions

To get a working developement setup, issue the following command rather than those above:

make dev-setup

This will create an Opam local switch that provides you with a development environment known to be working. As usual with Opam, you must always ensure that the local switch is taken into account when developing (e.g. by typing eval $(opam env)).

To build Electrod in development mode, just type make.

To work in development mode, using make watch is suggested: it watches the source and, each time it's updated, checks it quickly and reformats it using ocamlformat.

External dependencies

As of now, Electrod relies on NuSMV (2.6+) or nuXmv (2.0+), so you must at least install one of them.

Running

Electrod is primarily aimed at being called by external tools such as the Electrum Analyzer.

However, it can also be run as a standalone tool by calling the electrod program.
Type electrod --help to get some help on options.
