Multi-methodology design: an experimental comparison

The paper presents a multi-methodology design process model incorporating multiple design approaches. Design productivity is quantified by measuring effort (time) required for various activities in HDL-based design. An experimental comparison is carried out to measure time required for various activities involved in textual HDL-based design and multi-methodology design. We also discuss factors influencing design productivity in multi-methodology design and merits of using multiple design approaches for integrated system design. It is shown that use of multi-methodology design, with or without design reuse, contributes towards enhanced design productivity achieving time-to-marker savings.
