Improving the Digital Design with Semi-formal Specification

Abstract

In this work, an improvement of the traditional design methodology is proposed. The major change is the use of semi-formal specification for the implementation and the establishment of properties for the formal verification. From semi-formal specification, assertions were written using Property Specification Language (PSL) for an alignment circuit. Finally, a set of properties for the verification of this module were established and proved using two verification tools. Our statistics proved that, considerable design time was saved, and the number of versions was low.
