This report presents the results from the 2021 friendly competition in the ARCH work- shop for the falsification of temporal logic specifications over Cyber-Physical Systems. We briefly describe the competition settings, which have been inherited from the previ- ous years, give background on the participating teams and tools and discuss the selected benchmarks. Apart from new requirements and participants, the major novelty in this instalment is that falsifying inputs have been validated independently. During this pro- cess, we uncovered several issues like configuration errors and computational discrepancies, stressing the importance of this kind of validation.

This report presents the results from the 2020 friendly competition in the ARCH workshop for the falsification of temporal logic specifications over Cyber-Physical Systems. We briefly describe the competition settings, which have been inherited from the previous year, give background on the participating teams and tools and discuss the selected benchmarks. The benchmarks are available on the ARCH website1, as well as in the competition’s gitlab repository2. In comparison to 2019, we have two new participating tools with novel approaches, and the results show a clear improvement over previous performances on some benchmarks.
