Abstract :
A newly developed FDTD-SPICE hybrid simulation tool has been applied to the problem of ground bouncing. A simple example, that can be experimentally verified, was considered and modeled. A 30 MHz pulse train coming at the input of a buffer IC caused disturbances in the power line of the PCB. The modeling allows a designer to estimate precisely the bouncing adverse consequences and to anticipate the effect for countermeasures. Experimental results validate the computations. The analysis tool and methodology may be applied to very complicated PCB and circuits with many ICs
