1. A method of controlling a clock of an integrated circuit (“

  • IC”

    ) comprising a plurality of groups of configurable circuits for configurably performing operations of a user design based on configuration data, said method comprising;

    commencing operation of said IC based on said clock; and

    at a particular clock cycle of said clock;

    adjusting a clock control value stored in a storage element located on a same IC die as said groups of configurable circuits;

    determining whether the clock control value is equal to a predetermined value; and

    upon determining that the clock control value is equal to a predetermined value, halting said clock in order to allow one or more of said groups of configurable circuits to be accessed, wherein said adjusting, determining, and halting are performed by clock control circuitry on the same IC substrate as the configurable circuits, and wherein the clock control circuitry comprises a clock control circuit, a counter, and a logic gate.
