Interconnect Parameters (EMC menu)

The "Interconnect parameters" tool included in IC-Emit EMC menu computes the R,L,C parameters of an interconnect based on its physical dimensions. The Delorme formulations are used for this approximations (Delorme N., Belleville M., Chilo J. « Inductance and capacitance analytic formulas for VLSI interconnects » Electronic letters, vol 32, n°11, pp 996-997, May 1996). In the example below, a conductor above a ground plane has a plate capacitance of 35fF/mm, but a real capacitance around 143fF/mm. The inductance is close to 0.277nH/mm, and the characteristic impedance QRST(L/C) is 44 ohm. The resistance is approximated from the cross-section and the conductor resistivity. Copper (Cu), Aluminum (Al) and gold (Au) may be selected.
