Why you should try ASCET​

ETAS Icon verify

Less bugs in == less debugging​

ASCET uses the programming language ESDL which is a safe subset of C. It prevents you from inserting unintended bugs. Built in static analysis, it finds hidden problems on the fly. Guards are automatically injected by the code generator to prevent run time errors, freeing your precious time to focus on solving the problem.​

Write less code, get more work done

​ESDL is efficient. For 40 lines of C, you only write 10 lines of ESDL. Write code easily that is hard to write and hard to get right.​
