Abstract

The effects of parameter variations and crosstalk noise on the clock signal propagating along an H-tree clock distribution network are investigated in this paper. In particular, the effects of variations in power supply voltage (V_DD), and temperature on the delay and the transition time of the clock signal are evaluated. Furthermore, the effects of crosstalk between an H-tree structure and other interconnect wires are investigated. Different scenarios of capacitive coupling along different spatial locations of an H-tree are considered. The effects of coupling on the propagation delay, the transition time, and the waveform shape of the clock signal are demonstrated
