1. A computerized system comprising: a processor; a first interface configured to obtain a constraint; a second interface configured to obtain a first model, wherein the first model is configured to be utilized in model checking, and the first model, when constrained by the constraint, comprises at least one finite path; and a finite path removal module implemented in the processor and configured to generate a second model equivalent to the first model obtained by said second interface, wherein the second model excludes a portion of the at least one finite path, and the second model is configured to be utilized in model checking.
