We report on recent advances in the development of the PEPA Eclipse Plug-in, a software tool which supports a complete modelling workflow for the stochastic process algebra PEPA. The most notable improvements regard the implementation of the population-based semantics, which constitutes the basis for the aggregation of models for large state spaces. Analysis is supported either via an efficient stochastic simulation algorithm or through fluid approximation based on ordinary differential equations. In either case, the functionality is provided by a common graphical interface, which presents the user with a number of wizards that ease the specification of typical performance measures such as average response time or throughput. Behind the scenes, the engine for stochastic simulation has been extended in order to support both transient and steady-state simulation and to calculate confidence levels and correlations without resorting to external tools.
