ABSTRACT:
Systems and methods are disclosed for programmable logic devices requiring a high-speed input/output interface. Hard-macro circuits that are configurable, scalable, and cascadable complement the input/output drivers and the programmable core logic of the programmable logic device. The hard-macro circuits are permanent, high-speed logic circuits that are optimized for the performance requirements of high-speed input/output interface standards. High-speed memory interfaces, clock and data recovery interface standards, source-synchronous interface standards, and system-synchronous interface standards may be supported by the hard-macro circuits.
