Finding DU-Paths for Testing of Multi-Tasking Real-Time Systems using WCET Analysis

Abstract
Memory corruption is one of the most commonsoftware failures. For sequential software and multi-
tasking software with synchronized data accesses, it has
been shown that program faults causing memory cor-
ruption can be detected by analyzing the relations be-
tween defines and uses of variables (DU-based testing).
However, such methods are insufficient in preemptive
systems, since they lack the ability to detect inter-task
shared variable dependencies. In this paper, we propose
the use of a system level shared variable DU analy-
sis of preemptive multi-tasking real-time software. By
deriving temporal attributes of each access to shared
data using WCET analysis, and combining this infor-
mation with the real-time schedule information, our
method also detects inter-task shared variable depen-
dencies. The paper also describes how we extended the
SWEET tool to derive these temporal attributes.
