Abstract
Driver circuitry for programmable logic devices may include a module comprising a driver and associated hardware-programmable input and/or output routing connection. Instances of the generalized driver module may be included anywhere on the programmable logic device that driver circuitry having characteristics within the capabilities of the generalized module is needed. The circuitry of each instance of the module is hardware-customized to match the driver characteristics required for that instance. Driver circuits may be distributed throughout the interconnection conductor resources of the programmable logic device in such a way as to optimize re-buffering of signals propagating through those resources.
