Early Estimation of the Size of VHDL Projects

The analysis of the amount of human resources required to complete a project is felt as a critical issue in any company of the electronics industry. In particular, early estimation of the effort involved in a development process is a key requirement for any cost-driven system-level design decision. In this paper, we present a methodology to predict the final size of a VHDL project on the basis of a high-level description, obtaining a significant indication about the development effort. The methodology is the composition of a number of specialized models, tailored to estimate the size of specific component types. Models were trained and tested on two disjoint and large sets of real VHDL projects. Quality-of-result indicators show that the methodology is both accurate and robust.
