A net-based semantics for VHDL

Abstract

The VHDL standard gives only an informal description of the semantics of VHDL. To apply formal verification techniques, a precise semantics definition is necessary. A formal semantics for VHDL based on interpreted Petri nets is defined. The presented semantics is compositional and provides a link to automatic verification methods for VHDL based designs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
