Quaternary Arithmetic Logic Unit on a Programmable Logic Device

Common binary arithmetic operations such as addition/subtraction and multiplication suffer from O(n) carry propagation delay where n is the number of digits. Carry lookahead helps to improve the propagation delay to O(log n), but is bounded to a small number of digits due to the complexity of the circuit. A carry-free arithmetic operation can be achieved using a higher radix number system such ...

Regression Verification for Programmable Logic Controller Software

Automated production systems are usually driven by Programmable Logic Controllers (PLCs). These systems are long-living – yet have to adapt to changing requirements over time. This paper presents a novel method for regression verification of PLC code, which allows one to prove that a new revision of the plant’s software does not break existing intended behavior. Our main contribution is the des...
