shoot-through is when H-bridges (or totem-pole outputs or CMOS logic cells) have both their pass elements turned on at the same time as they transition from one state to the other, therefore behaving briefly as a short to ground. think of those decoupling caps on logic devices as local, low-inductance sources for shoot-through energy and the gate charges being moved to and fro. and think of those wires (and component leads) as inductors (and antennas). the natural consequence of such thinking is to put those supply caps right on top (or under) the chip in question with the shortest leads practical, Pic related
