pyCPA_TWCA: A pyCPA plugin for computing deadline miss models

Functional Description

We are developing pyCPA_TWCA, a pyCPA plugin for Typical Worst-Case Analysis as described in Section  7.2.5 . pyCPA is an open-source Python implementation of Compositional Performance Analysis developed at TU Braunschweig, which allows in particular response-time analysis. pyCPA_TWCA is an extension of this tool that is co-developed by Sophie Quinton and Zain Hammadeh (TU Braunschweig). It allows in particular the computation of weakly-hard guarantees for real-time tasks, i.e., the number of deadline misses out of a sequence of executions. So far, pyCPA_TWCA is restricted to uniprocessor systems of independent tasks, scheduled according to static priority scheduling. A public release is planned for 2016.
