Release of pi-fp (and source code) to end-users

Anasim releases pi-fp along with its GUI and simulation source code to end-users under a Creative Commons by-nc license. The pi-fp project archive may be downloaded from Anasim’s PI-FP page.

Written in C++ and developed in a platform independent development environment (Qt from Nokia®), pi-fp sports an intuitive graphical user interface and interactive 3D interconnect / simulations results visualization. It is the first CAD tool to provide a physical design schematic capture environment for chip/system power integrity analysis. pi-fp is also the first simulation environment that employs innovative modeling and simulation algorithms (ECD) to include key aspects of power integrity verification in a true-physical manner.

RLCSim is a Windows(tm) executable that performs noise analysis on a power grid over a circuit block. 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.
