“…The distributed nature of our power grid model, and the fine-grained spatio-temporal localization of current could be contributors to this effect. Previous work [6] expands on this topic. Different shapes of voltage fluctuations have different impli cations for timing.…”

“…1 b), we base this extraction on detailed power simulations using PrimeTime PX (PTPX). In our previous work [6], the single vector used was associated with the clock cycle that was reported, by PTPX, to have the highest average power dissipation; a common method for selecting a vector. This time we use the extended time-based power analysis output of PTPX.…”

“…Given specific process technology data, a commercial field solver creates a netlist of inductances and resistances rep resenting the power grid. This part of our approach has been described previously [6]. With this approach we construct a current signature in time and space by interpolating the switching currents for each of the transitions of a selected part of a VCD trace.…”

We present an approach to power integrity analysis that is based on traces resulting from application execution. The first phase of the approach identifies a vector that maximally stresses the power grid, while the second phase entails simulation of the selected vector on an accurate grid model. We show, for an AV R32 32-bit microcontroller, that the vector we identify gives rise to a supply voltage drop that is 18% larger than that of the vector obtained in a regular flow, which considers average power dissipation per cycle.
