Zusammenfassung
In this work, we identify the power-optimal wire spacing as a geometric program. Its solution is a vector of individual distances between the wires. To quantify the optimization potential by this method we model the output of a grid based router with a set of parallel wires. A comparison of the power values before and after geometric optimization shows that the optimization potential lies well in the two digit percent zone for a representative circuit model in a 130nm process.
