    摘要: A programmable logic integrated circuit device is provided with enhanced capability for dynamically multiplexing signals on the device. Controllable connectors that are provided on the device for connecting any of several connector input signals to a connector output are controlled by control signals that can be programmable selected to be either constant or variable signals. If a control signal is selected to be a variable signal, then the connector controlled by that control signal can be operated as a dynamic multiplexer of the input signals to that connector. The controllable connectors may advantageously be used as the connectors that are employed for allowing several possible signal sources to effectively share a smaller of number of signal drivers.

    摘要: A programmable logic array integrated circuit device has regions of programmable logic grouped in blocks disposed on the device in a two-dimensional array of intersecting rows and columns. Each block includes a relatively small number of logic regions to reduce the size and complexity of the local feedback circuity required in the block. Interconnection conductors extend along each row and column of blocks. Some of these conductors are segmented along their length to permit independent use of each segment. When longer interconnections are required, however, adjacent segments can be interconnected by programmable bi-directional switches between the segments.

    摘要: A programmable logic array device in which programmable logic regions are arranged in groups of four is provided. The device includes direct connect conductors for carrying signals totally within one group of four regions as well as to certain adjacent programmable logic regions, local conductors for carrying signals within groups and among adjacent groups, and global conductors for carrying device-wide signals. Connections among the various conductors, and between conductors and programmable logic regions, are provided to optimize the connection resources by avoiding switched conductor paths wherever possible.

    摘要: Redundant circuitry for a logic circuit such as a programmable logic device is provided. The redundant circuitry allows the logic circuit to be repaired by replacing a defective logic area on the circuit with a redundant logic circuit. Rows and columns of logic areas may be logically remapped by row and column swapping. The logic circuit contains dynamic control circuitry for directing programming data to various logic areas on the circuit in an order defined by redundancy configuration data. Redundancy may be implemented using either fully or partially redundant logic areas. Logic areas may be swapped to remap a partially redundant logic area onto a logic area containing a defect. The defect may then be repaired using row or column swapping or shifting. A logic circuit containing folded rows of logic areas may be repaired by replacing a defective half-row with a redundant half-row.

    摘要: A programmable logic array integrated circuit device has logic regions grouped in blocks, which are in turn grouped in super-blocks. The super-blocks are disposed on the device in a two-dimensional array of intersecting rows and columns. Global conductors are associated with each row and column. Super-block feeding conductors associated with each super-block feed signals from the global conductors to any logic region in the super-block. Local feedback conductors feed back logic region output signals to all logic regions in a block. The super-block feeding conductors are also used to interconnect the logic regions in a super-block so that the global conductors do not have to be used for that purpose.
