John Lauer adom-fields 0.7.8: plane resonance and crosstalk, each with an action, and the Noise view a4d399b

adom-fields 0.7.8

  • Plane resonance. Each power or switching pour over the ground plane: its lowest cavity modes solved on the real overlap; a mode near a strong switching harmonic or a named clock is cavity-resonance, with a damping capacitor at its loudest point.
  • Crosstalk. Each quiet net near a switching node or clock: the coupled step per edge from side and overlap capacitance; over budget is crosstalk, with a reroute or ground-guard action. A bootstrap net tied to the switch node through its capacitor is not a victim.
  • The Noise view draws both: the largest cavity ringing in 3D, the switching copper pulsing, the victims glowing. A narrated video on the page.
  • Spec: clocks (net: Hz), crosstalkMv (50).
