Abstract
Described herein is an ASIC having an array of predesigned function blocks. The function blocks can be used to implement combinational logic, sequential logic, or a combination of both. The function blocks also have a selectable output drive strength. The output drive strength can be selected, in some embodiments, using mask programming.
