Understanding and validating the timing behavior of real-time
systems is not trivial.
Many real-time operating systems and their development environments
do not provide tracing support, and provide only limited visualization,
measurements and analysis tools.
Grasp<http://www.win.tue.nl/san/grasp/>_ is a
tool for tracing, visualizing and measuring the behavior of real-time
systems. It provides a simple plugin infrastructure for extending Grasp
with custom visualization and measurement methods.
