Abstract: An ASIC is disclosed that is formed on a die with multiple functional blocks distributed on the die, each functional block being able to send and to receive data, and each having two inputs labeled slow and fast. The slow input may have a delay component that creates a delay in receiving a data signal, and the fast input may have less delay than the slow input. A switch may be used to couple the slow input and the fast input of a receiving functional block to a data signal based on a distance of the receiving functional block from a sending functional block. The delay in the slow input is used to adjust input data timing to meet setup and hold timing specifications of the functional blocks without altering the ASIC circuit components aside from the functional blocks.
