Dedicated local line interconnect layout

DETAILED DESCRIPTION An electrical connection arrangement for a programmable integrated circuit is described.
An electrical device is disposed proximate to a vertical arranged longline which is used for transporting address and data signals.
The electrical device has a vertical address line extending from the device.
A horizontally arranged interconnection line is permanently connected to the vertical address line extending from the device.
Furthermore, the horizontally arranged interconnection line is programmably connectable to the vertical longline arranged proximate to the electrical device.
By permanently connecting the horizontally arranged interconnection line to the vertical address line extending from the device, only one programmable interconnect point is required to transfer signals from the vertical longline into the electrical device.
Thus, impedance is reduced, while addressing speed is improved.
Also, by adding additional horizontal interconnect lines, the present invention reduces routing barriers.
In one embodiment of the present invention the electrical device includes a configurable logic block having a look-up table.
The vertical address line extends from the look-up table and is hardwire connected to the horizontal local interconnect line.
The horizontally arranged local interconnect line is disposed across a vertical global longline for programmably coupling thereto.
Also included in one embodiment is a second horizontal local interconnect line disposed across the vertical global longline and the vertical address line.
The second horizontally arranged local interconnect line is adapted to programmably couple to the vertical address line.
