METHOD AND APPARATUS FOR IMPLEMENTING BALANCED CLOCK DISTRIBUTION NETWORKS ON ASICS WITH VOLTAGE ISLANDS FUNCTIONING AT MULTIPLE OPERATING POINTS OF VOLTAGE AND TEMPERATURE |
摘要 |
A method and apparatus implement balanced clock distribution networks on application specific integrated circuits (ASICs) with voltage islands functioning at multiple operating points of voltage and temperature, and a design structure on which the subject circuit resides is provided. A clock source is coupled to an N-level balanced clock tree providing a clock signal. Each of a plurality of voltage islands includes a respective voltage shifter and programmable delay function receiving the clock signal. Each respective voltage shifter and programmable delay function provides a second clock signal to a respective balanced clock tree for the associated voltage island. A system controller provides a respective control input to each respective voltage shifter and programmable delay function. The respective control input is varied dynamically corresponding to an operational mode of the respective voltage island.
