OTAWA v2 is in development since 2 years. New features include (but are not limited to): otawa-install.py — automatic installer/compiler for OTAWA optional modules (instruction, micro-architecture, analyses, etc) otawa-stat.py — generation of statistics for a WCET analysis, new CFG system…
OTAWA is an open source framework to compute WCET. It allows computing WCET but provides also a sound framework to support new architectures.
