Solutions For Mixed-Signal IP, IC, And SoC Implementation
Traditional mixed-signal design environments, in which analog and digital parts are implemented separately, are no longer sufficient and lead to excess iteration and prolonged design cycle time. Realizing modern mixed-signal designs requires new flows that maximize productivity and facilitate close collaboration among analog and digital designers. This paper outlines mixed-signal implementation challenges and focuses on three advanced, highly integrated flows to meet those challenges: analog-centric schematic-driven, digital-centric netlist-driven, and concurrent mixed-signal. Each flow leverages a common OpenAccess database for both analog and digital data and constraints, ensuring tool interoperability without data translation. Each flow also offers benefits in the area of chip planning and area reduction; full transparency between analog and digital data for fewer iterations and faster design closure; and easier, more automated ECOs, even at late stages of design.
