This report presents the results from the 2021 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 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 process, we uncovered several issues like configuration errors and computational discrepancies, stressing the importance of this kind of validation. Data:,
