ABSTRACT:
The present invention is directed to a programmable logic device and a method of programming a programmable logic device that features providing a verification technique to ensure the requisite functional operations of an array of configurable logic blocks may be programmed while limiting a user from altering the functional operations of the configurable logic blocks of the programmable logic device to having functional operations in addition to and/or different from the functional operations of that a vendor desires a user to have. In this manner, the array of configurable logic blocks can be designed so that the same may be programmed to provide one or more of multiple different functional operations, while limiting a user to a desired set of functional operations.
