TIPPtool: Compositional Specification and Analysis of Markovian Performance Models. H. Hermanns, V Mertsiotakis, and M. Siegle. In: Computer Aided Verification (CAV) 99, Springer, LNCS 1633. In this short paper we briefly describe a tool which is based on a Markovian stochastic process algebra. The tool offers both model specification and quantitative model analysis in a compositional fashion, wrapped in a user-friendly graphical front-end.
