Abstract

For an integrated circuit (IC) that is designed to execute user defined operations after initialization, a sequencing circuitry in the IC that delays the start of the user design execution until a set of initial condition has been computed and propagated is provided. The sequencing holds the first group of circuits at an initial state while a second group of circuits computes and propagates a set of initial conditions based at least partly on the initial state of the first group of circuits. The circuits in the first group when being held disregard their inputs and do not change their outputs. The first group of circuits is released from its initial state after the second group of circuits has completed computation and propagation of the set of initial conditions. The circuits in the first group when released are freed to store or clock-in new inputs and produce new outputs in order to perform the user defined operations in conjunction with the second group of circuits.
