SCROOGE Power optimization made easy - December 2009
SCROOGE is the power consumption analyzer for simulating mixed-signal power consumption hierarchically. Whereas common solutions enable statistical or average power consumption analysis, the main advantage of SCROOGE is to provide hierarchical evaluation of power consumption: both logic (leakage and dynamic) and analog, during transient simulation.
SCROOGE 2.0 Mixed-Signal Power Consumption - June 2008
Power Consumption of logic parts of a SoC is one face of the coin, the other face of which is Noise Resilience of analog parts. Reducing the peaks of a dynamic mixed-signal power consumption simulation grants the consistent benefit of smoothing-out the disturbances threatening high-resolution analog parts, including sensitive read-margins of logic parts.
Power analysis is best performed in the time domain, while noise resilience is best analyzed over the spectral domain. SCROOGE 2.0 unifies hierarchical mixed-signal power consumption and provides the missing simulation capability!
The development of portable devices with high performance and multiple features, combined with the arrival of nanometer technologies, makes mixed-signal SoC power consumption a critical point which designers have to deal with during the whole development. The analysis of power consumption has to be performed at the earliest stage in the development flow, so that designers may anticipate potential issues and adapt the architecture with no need for backtracking. Keep control of the power consumption all along the design chain with SCROOGE.
