ABSTRACT:
Programmable integrated circuits (ICs) that compensate for process variations and/or mask revisions in a programmable integrated circuit (IC). An exemplary IC includes two programming ports, two programmable circuits (e.g., digital and analog), a non-volatile memory, and a configuration control circuit coupled to the programmable circuits and non-volatile memory. In some embodiments, one port can be used for storing data in the non-volatile memory, while the other port can be used for providing a configuration bitstream to the configuration control circuit. The non-volatile memory can be used to store a value that identifies a process corner and/or mask revision for the programmable IC. The configuration control circuit monitors data arriving in the configuration bitstream, and selectively either ignores the data or uses the data to configure the IC (e.g., the analog circuit), based on a comparison of a code key in the bitstream with the value stored in the non-volatile memory.
