    The trends in CMOS chip design have all been converging to worsen coupling between horizontally and vertically adjacent wires. The coupling between on chip wires can cause two different types of problems, namely, functional fails due to the induced coupled noise voltage, and changes in delay due to the changes in load capacitance caused by switching the activity of adjacent wires. A methodology ba... View full abstract»

    Summary form only given. A microprocessor's clock distribution network provides a spine around which the performance is built. Clock skew penalizes the overall performance by adding to the maximum delay path. In addition it subtracts from minimum delay paths increasing the risk of a hold time failure. Uncompensated delay in the clock distribution shifts I/O timings, increasing output delays and ho... View full abstract»
