DARPA POSH Program
Modern day SoCs incorporate analog mixed-signal (AMS) components, such as SERDES, power conditioners, converters, filters, and high-speed DDR memory. The designs are a challenge for hardware verification. In DARPA’s POSH program Synopsys has led the development of Analog Mixed-Signal hardware-based emulation. This technology can overcome the limitations of current accelerated simulation technology, such as the lack of support for floating point signals, analog math operations, timing of intermixed analog and digital logic controls, analog outputs, and other AMS design verification not available with today’s digital only emulators. This capability is complemented by automated behavioral modeling of AMS components and by programmable checks that replace manual debug. These combined techniques achieved 100x verification performance increases over software-based simulation.
