Signal integrity has become a critical issue in the design of high-speed systems. Poor signal integrity can
mean increased engineering costs, delayed product releases, and even lost revenues. The opportunity cost
of ignoring signal integrity can easily reach millions of dollars, given the importance of time-to-market in
today’s semiconductor marketplace. The onus on sound signal integrity inevitably falls on the choice of
FPGA in high-speed systems.
This white paper describes competitive benchmarks between Stratix® II and Virtex-4 FPGAs demonstrating
a 2X signal integrity advantage for Stratix II FPGAs. This paper also describes the Altera design process
to deliver industry leading signal integrity and the resulting technology within Stratix II FPGAs that enable
this significant advantage.
