SCROOGE 2.0 Mixed-Signal Power Consumption   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!   Key enhancements Unified hierarchical mixed-signal power consumption simulation Analog power consumption reporting Signal driven power simulation with testbench enable/disable Clock based leakage and dynamic cycle power consumption simulation Hierarchical browsing of power map, both online and as post-processing Extraction of cycle power signature: min, max, average and std deviation Streamlined graphic user interface Enhanced power consumption report with color scales Extended support of SPEF back-annotation Increased capacity and reduced SDF annotation memory requirements   Description of the enhancements Optimizing the power consumption of a SoC requires being able to hierarchically simulate mixed-signal power at various accuracy levels, from time-accurate, through cycle-accurate, up to mode-accurate (from a Virtual Component point-of-view) and state-accurate (from a testbench point-of-view), thereby providing the means to efficiently assess and implement power saving techniques. Clock-based power analysis enables cycle-accurate simulation by averaging the consumption over the clock period, providing analog, logic (leakage, internal and switching) and total power, and generating power consumption reports. Selection of a range of clock periods provides an intuitive hierarchical map view of the corresponding consumption. Signal-enabled power analysis enables mode or state-based simulation by controlling the activation of power calculations during the transient analysis. A reset, simple enable, or complex expression associated to a controlling signal enables focusing the power display and reporting on a specific mode or state.   SCROOGE in µWatts powerful for productivity   < SCROOGE Evolution over time
