Abstract
An electrical connection arrangement for a programmable integrated circuit is provided. An electrical device is disposed proximate to a vertical longline which is used for transporting address and data signals. The electrical device includes a vertical address line extending from the device. A horizontally arranged interconnection line is electrically connected to the vertical address line extending from the device. Furthermore, the horizontally arranged interconnection line is programmably connectable to the vertical longline. By electrically hardwire 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 itself. Thus, impedance is reduced, while addressing speed is improved. Also, by adding additional horizontal interconnect lines, the present invention reduces routing barriers.
