Part 4- Power management in OCP-IP 3.0
According to Moore’s Law, system-on-chips (SoCs) should continually become more complex and integrate more components, enabled by each reduction in silicon technologies. However, power consumption does not follow the linear path implied here due to increasing leakage in deep sub-micron technologies. Hence, new power management techniques are needed to reduce power dissipation as much as […]
Extending UPF for incremental growth
Erich Marschner Accellera’s Unified Power Format (UPF) is in production use today, delivering the low-power system-on-chip (SoC) designs that are so much in demand. Building upon that success, IEEE Std 1801-2009 [UPF] offers additional features that address the challenges of low-power design and verification. These include more abstract specifications for power supplies, power states, and […]
A holistic approach to low-power verification
The article describes a dedicated low-power functional verification methodology, originally developed at STMicroelectronics (now ST-Ericsson). The article details the content, sequence and effectiveness of the methodology as it was tested on a 45nm system-on-chip design. In order of use, the main components are: A high-level verification language testbench Formal verification Rule checking C function library […]
