Tests and instances notes

This folder contains some model instances conforms to the seim and pseim metamodels.

Models details

ArchiImplemOcaml.seimx

This model contains the structure of the OCaml code provided as an implementation of the pattern instantiation and application Event-B model.

Test_MoonG_1

First test

The pattern files for this test is N-Version Programing.pseimx. It represents the "N Version Programming" pattern provided in [1].

Parameters of the pattern:

• comp: a component that is replicated
• nb_in: the number of input ports of the component that is replicated
• nb_out: the number of output ports of the component that is replicated
• nb_comp: the number of times the component is replicated

First instantiation

Patter instanciation inputs:

• The source model (source.seimx)
• The pattern instantiation parameters values: comp = System.Sub1; nb_in = 2; nb_out = 1; nb_comp = 3

Pattern elaboration:

• unfold.seimx

Pattern application:

• result2.seimx

Second instantiation

Patter instanciation inputs:

• The source model (source2.seimx)
• The pattern instantiation parameters values: comp = System.Sub1; nb_in = 2; nb_out = 2; nb_comp = 3

Pattern elaboration:

• unfold_1.seimx

Pattern application:

• result.seimx
