Problem Definition
The power grid of an integrated system is responsible for providing reliable supply and ground voltages to every circuit element in the system. Degradations in the supply voltage levels can result in parametric failures due to increased delays, whereby circuits no longer meet their specifications, as well as catastrophic failures due to incorrect gate switching. Further, power grids are susceptible to reliability faults due to catastrophic failure modes such as electromigration. Therefore, accurate power grid analysis is a vital step in integrated circuit design.
Power grids may be analyzed under DC waveforms that reflect the steady-state currents drawn by the circuit or under transient analysis that captures the response of the grid to specific time-varying current waveforms; inductive effects, particularly in the...
