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.
