Abstract
A configurable logic block ('CLB') in a programmable logic device ('PLD'), such as a complex programmable logic device (“CPLD”) or a field programmable gate array (“FPGA”), routes a timing signal, such as an external clock signal, through the CLB to provide a selected delay. The timing signal is routed through selected fast or slow pins of look-up tables (“LUTs”) in the CLB. CLBs are widely available in the PLD, allowing many timing signals to be delayed, and can be configured to account for board-specific or component-specific delays.
