Abstract:
1. A programmable logic device comprising a single die and having, on said single die: at least one region of programmable logic; at least one input/output region in electrically conductive relationship with said at least one region of programmable logic for providing input/output functions to said at least one region of programmable logic; and at least one specialized circuitry region distributed in a peripheral area of said single die surrounding said at least one region of programmable logic and said at least one input/output region, each of said at least one specialized circuitry region comprising at least one of a plurality of types of high-speed serial interface circuitry; wherein: each said specialized circuitry region is electrically isolated from each other said specialized circuitry region, from said at least one region of programmable logic, and from said at least one input/output region; and each of said at least one of a plurality of types of high-speed serial interface circuitry in said at least one specialized circuitry region, and at least one of (a) said at least one region of programmable logic and (b) said at least one input/output region, has at least one contact for accepting an interconnection for connecting, externally of said die, said at least one of a plurality of types of high-speed serial interface circuitry to at least one of (a) said at least one region of programmable logic and (b) said at least one input/output region; said programmable logic device further comprising: at least one said external interconnection between a contact on one of said types of high-speed serial interface circuitry and one of (a) said at least one region of programmable logic and (b) said at least one input/output region, to form one of a plurality of programmable logic device products according to placement of said external interconnection.
