Successful use of incremental BMC in the automotive industry
chapter
posted on 2023-06-09, 00:30 authored by Peter Schrammel, Daniel Kroening, Martin Brain, Ruben Martins, Tino Teige, Tom BienmüllerProgram analysis is on the brink of mainstream usage in embedded systems development. Formal verification of behavioural requirements, finding runtime errors and automated test case generation are some of the most common applications of automated verification tools based on Bounded Model Checking (BMC). Existing industrial tools for embedded software use an off-the-shelf Bounded Model Checker and apply it iteratively to verify the program with an increasing number of unwindings. This approach unnecessarily wastes time repeating work that has already been done and fails to exploit the power of incremental SAT solving. This paper reports on the extension of the software model checker Cbmc to support incremental BMC and its successful integration with the industrial embedded software verification tool BTC EmbeddedTester. We present an extensive evaluation over large industrial embedded programs, mainly from automotive industry. We show that incremental BMC cuts runtimes by one order of magnitude in comparison to the standard non-incremental approach, enabling the application of formal verification to large and complex embedded software.
