Field modelling of a multiconductor digital bus

A study of the transmission line parameters of a multiconductor transmission line, used as an on-chip digital interconnect is presented in this work. As a first step a quasi-static approach in connection with Schwarz-Christoffel mapping has been used to determine the capacitance per unit length values. Then the obtained results have been used to solve the multiconductor transmission line equations in frequency domain. The resulting frequency response was used to compute the pulse distortion and the crosstalk effect in a real-case on-chip digital.
