Abstract
Abstract An interconnect structure enables indirect routing in programmable logic. The structure includes a plurality of routing lines, and switch box(es) and connection boxes coupled to the plurality of routing lines. The connection boxes include at least one programmable switch in each routing track. The position of the programmable switch(es) in each connection box connected to same interconnect matrix differs from the position of said programmable switch(es) in corresponding routing tracks of other connection boxes thereby utilizing the connectivity of said switch box for input connections and increasing the flexibility of connections.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
136 words
An apparatus comprising: a logic cluster; a switch box having first side channels, second side channels, third side channels and fourth side channels, each of said side channels comprising a plurality of routing tracks arranged in a certain order; a connection box associated with each of the first through fourth side channels for connecting routing tracks of the associated side channels to the logic cluster through a corresponding plurality of input lines; wherein each connection box includes a plurality of programmable switches, each switch interconnecting one input line to one routing track; and wherein the programmable switches in the first through fourth connection boxes connected to a certain one of the input lines interconnect, with respect to the certain order, to different ones of the routing tracks in each of the first through fourth connection boxes.
Claim 2
Independent Claim
136 words
An apparatus comprising: a logic cluster; a switch box having first side channels, second side channels, third side channels and fourth side channels, each of said side channels comprising a plurality of routing tracks arranged in a certain order; a connection box associated with each of the first through fourth side channels for connecting routing tracks of the associated side channels to the logic cluster through a corresponding plurality of input lines; wherein each connection box includes a plurality of programmable switches, each switch interconnecting one input line to one routing track; and wherein the programmable switches in the first through fourth connection boxes connected to a certain one of the input lines interconnect, with respect to the certain order, to different ones of the routing tracks in each of the first through fourth connection boxes.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 , wherein said plurality of input lines and said plurality of routing tracks form a corresponding plurality of domains, and wherein the plurality of programmable switches enable interconnection among and between the domains.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 , wherein said switch box includes Wilton switch boxes.
