Abstract:
Logic modules 22 in a programmable logic array integrated circuit device each include programmable logic feeding a register. Secondary signals such as clocks and clears for the registers can be drawn 120 either from dedicated secondary signal conductors 50e,f or normal region inputs.
Abstract:
A programmable logic device has a plurality of super-regions of programmable logic disposed on the device in a two-dimensional array of intersecting rows and columns of super-regions. Each super-region may be like a small or moderately sized programmable logic device and may include a two-dimensional array of intersecting rows and columns of regions of programmable logic. Each region may in turn include a plurality of subregions of programmable logic. Horizontal and vertical inter-super-region interconnection conductors are associated with the rows and columns of super-regions. These conductors are selectively connectable to horizontal and vertical inter-region interconnection conductors in the super-regions.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for detecting an error in a configuration memory of a programmable device. SOLUTION: The method for detecting errors in the configuration memory of the programmable device includes: reading configuration memory data from the configuration memory; determining whether an error occurs in the configuration memory data; reading sensitivity data corresponding to the configuration data being the error in response to determination that the error occurs; analyzing the sensitivity data in order to determine whether the error can be ignored; starting a remedial activity when the error can not be ignored; and ignoring the error by not starting the repair activity when the error can be ignored.

Abstract:
A programmable logic array integrated circuit device includes a plurality of regions of programmable logic disposed on the device in a two-dimensional array of intersecting rows and columns of such regions. Each row has a plurality of adjacent horizontal conductors, and each column has a plurality of adjacent vertical conductors. The regions in a row are interspersed with groups of local conductors which interconnect the adjacent regions and the associated horizontal and vertical conductors. The local conductors can also be used for intra-region communication, as well as communication between adjacent regions. Secondary signals such as clocks and clears for the regions can be drawn either from dedicated secondary signal conductors or normal region inputs. Memory cell requirements for region input signal selection are reduced by various techniques for sharing these memory cells.
Abstract:
A programmable logic array integrated circuit device includes a plurality of regions of programmable logic 20 disposed in a two-dimensional array of intersecting rows and columns of such regions. Each row has a plurality of adjacent horizontal conductors 50, and each column has a plurality of adjacent vertical conductors 60. The regions 20 in a row are interspersed with groups of local conductors 40 which interconnect the adjacent regions (from both sides) and the associated horizontal and vertical conductors 50,60. The local conductors 40 can also be used for intra-region communication, as well as communication between adjacent regions 20. Secondary signals such as clocks and clears for the regions 20 can be drawn either from dedicated secondary signal conductors or normal region inputs. Memory cell requirements for region input signal selection are reduced by plural-stage progressively-finer selection.
