    Abstract: A field programmable gate array includes a programmable routing network, a programmable configuration network integrated with the programmable routing network; and a logic cell integrated with the programmable configuration network. The logic cell includes four two-input AND gates, two six-input AND gates, three multiplexers, and a delay flipflop. The logic cell is a powerful general purpose universal logic building block suitable for implementing most TTL and gate array macrolibrary functions. A considerable variety of functions are realizable with one cell delay, including combinational logic functions as wide as thirteen inputs, all boolean transfer functions for up to three inputs, and sequential flipflop functions such as T, JK and count with carry-in.

    Abstract: For each programmable logic block in a programmable logic device, a programmable power and speed control circuit is programmably configurable to generate an output signal on a power and speed control line so that the static power consumption of the corresponding programmable logic block is adjusted to provide a particular combination of power and speed for that programmable logic block, i.e., a specific power/speed performance point. For each programmable logic block in the programmable logic device, a plurality of programmable selectable speed/power levels are provided by the programmable power and speed control circuit. This allows a distribution of programmable logic blocks in the programmable logic device that are powered to various performance levels to match more closely a distribution of performance requirements by the circuit that includes the various programmable logic blocks.

    Abstract: A programmable ASIC architecture allows the size of programming transistors to be reduced along with other parts of the device as advances in processing technology are made. Programming enable circuits are used to allow a programming address shift register having fewer bits to be used in the programming of antifuses. Methods of simultaneously programming multiple corresponding antifuses to speed ASIC programming are disclosed. Aspects of the architecture allow output protection for digital logic elements in modules to be eliminated, some testing transistors to be eliminated, the sizes of other testing transistors to be reduced, capacitances on interconnect wire segments to be reduced, some programming transistors to be eliminated, and the sizes of other programming transistors to be reduced.

    Abstract: A programmable logic device architecture having a matrix of smaller functional units, each of which being a programmable logic array, and a set of fixed conductive lines connected to the functional unit inputs and outputs, the conductive lines forming programmable interconnection matrices. The input pins can be programmably connected to any input of any functional unit, and the outputs of functional units can be programmably connected to any input of any functional unit or any output pin. The interconnection matrices may be a simple array of crossing conductive lines with crossings connected by fuses, EPROM, or EEPROM switches or may have additional series switches to limit the effective impedance so as to speed propagation through these matrices. A fast path through one functional unit bypassing the interconnection matrices is available for a limited number of input and output pins. Multiplexers and other structures may be provided at ends of the fixed conductive lines to enable exhaustive testing of individual functional units, interconnections and logic, and structure may also be provided for on-chip monitoring of state information and providing the information to the external world when certain preselected events happen.
