This tool, a pre-cursor of pi-fp, considers grid resistance (IR drop), inductance (L*di/dt) or voltage droop, and distributed capacitance that absorbs transients, and displays noise propagation and summing within the block.

Inputs include grid parameters, block power consumption profiles and capacitance.

Shown below is a noise simulation result using RLCSIM demonstrating detrimental effects of lens-shaped on-chip decoupling capacitance structure. Power grid noise from an on-chip source is focused behind the capacitance structure, illustrating distributed true-electromagnetic simulation capability absent in other power integrity analysis tools.
