wayri/SPIKE
PCB-focused multiphysics simulation, from board to complete assembly: PI, SI, circuits, thermal, EM/RF and mechanical workflows, with MCAD collaboration and a roadmap toward large-scale coupled assemblies.
tombueng/emcvisual
EMC/EMI near-field simulator for KiCad PCBs in the browser: 3D field view, virtual near-field probe, spectrum, CISPR 32 estimate, return-path hints. EMV-Simulation für Leiterplatten.
gerhardmalberg/pcb-em-lab
Electromagnetic simulation for KiCad PCBs using Gmsh and Palace. Reproducible workflows for impedance, transmission lines and S-parameters. With CPU and CUDA support.
Jerome-Graves/kicad_fdtd
GPU FDTD field solver for KiCad boards: exact copper in, S-parameters, impedance and field views out (Python, CuPy)
Alberto0235/DRSSTC-Fiber-Optic-Interrupter
Custom 4-layer interrupter control board for DRSSTC systems. STM32F405-based, fiber-optically isolated outputs, hardware E-brake safety chain, and controlled-impedance routing (90Ω USB, 50Ω FSMC/SDIO).
