Escher C Verifier

C Verifier

Escher C Verifier enables the development of formally-verifiable software in a subset of C (based on MISRA-C 2004). It performs static analysis on the code, checks conformance with many of the MISRA rules, and verifies mathematically that the software is free from run-time errors and "undefined behaviour" for all inputs.

 

Optionally, Escher C Verifier can also verify that the software meets functional specifications. > Link to
