KiPI

KiPI is a power integrity analyzer that runs standalone or as a KiCad 9 and 10 IPC plugin, and reached version 1.0.0 (stable) on 2026-10-31. It has three analysis modes. DC voltage drop simulates voltage drop net by net across every copper layer, with voltage, current density, via currents, copper power dissipation, and optionally board temperature in a rotatable 3D view, with PASS/FAIL checks and an interactive HTML report or PDF. AC PDN impedance sweeps the power distribution network impedance over frequency against a flat or custom target. Coupled noise treats a buck or boost regulator as an aggressor and works out the noise it couples onto named signal nets, checked against each receiver logic family noise margin.

As a KiCad plugin it reads the board open in the PCB editor; KiCad 9.0.3 or later is required. Standalone, it opens KiCad 7 to 10 board files, ODB++ jobs, HyperLynx files, and KiPI snapshots, with no KiCad needed, and its launcher installs dependencies on first start. The author also wants to add support for more PCB file formats and asks for example boards in the README.

A Solver Guide on the project site explains what power integrity analysis is and how the mesh and the DC, thermal, AC, and coupled noise solvers work. The README states KiPI is free software under the GNU General Public License.
