  • Most featuresPVS · 2 of 2

PVS scores higher on our rubric for formal verification tools: 9.2 against 9.0 out of 10; our editors rank them #4 and #6.

On supported formalisms, PVS gives you Theorem-proving where NuSMV offers Temporal-logic.

PVS is the better fit for hybrid specification and model checking. NuSMV is the better fit for finite-state temporal-logic checking.

  • PVS fits best

    Hybrid specification and model checking

  • NuSMV fits best

    Finite-state temporal-logic checking

Our review
Pros
  • Combines higher-order theorem proving with BDD/CTL model checking
  • Supports SMT proving, random testing, and counterexample discovery
  • Runs on Linux, macOS, and Windows with useful integrations
  • Combines BDD symbolic and SAT-based bounded model checking
  • Checks CTL, LTL, PSL, and invariant specifications
  • Generates counterexample traces for failed properties
Cons
  • Its breadth requires expertise in formal methods and proof development
  • Self-hosted deployment places setup and maintenance on the user
  • Commercial use may require additional licensing through SRI
  • Focused on finite-state systems and SMV input models
  • Self-hosted deployment requires local installation and operation
  • Uses an interactive textual shell rather than a graphical interface
