# Formal verification at Intel

@article{Harrison2003FormalVA, title={Formal verification at Intel}, author={John Harrison}, journal={18th Annual IEEE Symposium of Logic in Computer Science, 2003. Proceedings.}, year={2003}, pages={45-54} }

As designs become more complex, formal verification techniques are becoming increasingly important in the hardware industry. Many different methods are used, ranging from propositional tautology checking up to use of interactive higher-order theorem provers. Our own work is mainly concerned with the formal verification of floating-point mathematical functions. As this paper illustrates, such applications require a rather general mathematical framework and the ability to automate special-purpose…
