Summary:In this paper, we present experimental results obtained during the
modeling, design, and implementation of a full set of versions of SPARC
v.8 Integer Unit cores aimed at embedded applications. VHDL is the
description language, Synopsys is the tool used for logical synthesis,
and Duet Technologies' Epoch for obtaining the physical layout of the
final circuits. These are mapped to 0.50- and 0.35-μm, three metal
layer processes in order to study the impact of VLSI scaling on SPARC
microarchitectural features. The quantitative results obtained
characterize suitable points in the design space. They show the extent
to which microarchitecture, design, datapath granularity, and megacell
decisions affect performance and cost functions. Design space
exploration down to physical layouts is made possible by modeling
techniques based on configurable VHDL descriptions
