Abstract:
A method for placing repeaters in a network in an integrated circuit comprising:identifying repeater location candidates in the network; determining a first set of repeaters of a first repeater size and a second repeater size; calculating delays using the first set of the first repeater size and the second repeater size; for each candidate location, determining which of no repeater, the first repeater size, or the second repeater size is optimum; determining a second set of repeaters of a third repeater size and a fourth repeater size; determining a third set of repeaters of a fifth repeater size and a sixth repeater size; calculating delays using the second set of repeaters for repeater location candidates in which the first size was optimum and the third set for repeater location candidates in which the second size was optimum; determining which of the third and fourth sizes is optimum; determining which of the fifth and sixth sizes is optimum; and making the integrated circuit using repeaters of a size closer to the third size than the fourth size for repeater location candidates which were optimum for the third size.
