The influence of the ground line position on the signal shape in the time domain is investigated in the presence of grounded substrates by M. F. Ktata et al. (2003) with different conductivities of 10 S/m (low) and 100 S/m (medium). It is shown that the impact of substrate effects on time domain signals depends on the substrate conductivity, on the relative position of the ground line with respect to the signal lines as well as on the length of the line system. In addition, the impact of process-related generated voids between closely spaced signal lines on crosstalk is investigated, too.
