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 6.2.5. 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, Zain Hammadeh (TU Braunschweig) and Leonie Ahrendts (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. This year, pyCPA_TWCA has been extended to task chains but remains limited to uniprocessor systems, scheduled according to static priority scheduling. A public release is planned but has not yet taken place.
