These naming conventions allow us to easily distinguish feature variables from ‘normal’ variables. All feature variables have the prefix f.f: the first f identifies the variable of

Our contributions are (i) a study of the foun- dations for symbolic SPL model checking with the intro- duction of fCTL, (ii) a symbolic algorithm to model check fCTL over FTS, (iii)

For example, when the number of features increases from eight to nine, the number of products increases from 36 to 48 and the runtime of the FTS algorithm grows only by 57 %, while

Among the branching-time temporal logics used for the spec- ification and verification of systems, CTL + , FCTL and ECTL + are the most notable logics for which the

Our analyses have revealed a number of interesting properties of the product line specification, such as the existence of an apparent disagreement between the constraints imposed on

Among the latter, there are a number of formal approaches that do not provide mech- anisms for the verification of temporal properties [23, 17, 16, 2, 32] as well as

It is thus the combination of our two contributions, a CTL-based extension of OCL, whose formal syntax and semantics extend the OCL standard without modifying existing definitions,

In our experiments (we have 790 malwares), our tool was able to detect all these programs as malicious (whereas when we model these programs using standard PDSs and abstract

The following subsignature relation on SPLSs naturally extends the one on program signatures (given in Definition 9) with the notion of feature model interface introduced in [8]

Abstract In a Model-based Software Product Line (MSPL), the variability of the domain is character- ized in a variability model and the core artifacts are base models conforming to

Apart from abstraction, there are many other uses of the simulation function we have defined. For instance, simulation-based verification allows one to verify properties modelled
