  • Patent number: 6804810
    Abstract: A method of designing a VLSI chip and a chip designed according to the method are described. The method includes the steps of early consideration of resistive and capacitive values during a VLSI chip design process. The method provides for estimation of signal routes between nodes of functional blocks to be incorporated in the chips. The estimation may be based on a floor plan describing the positioning of the functional blocks, a connectivity description identifying connections between ports of the blocks and physical and mechanical configuration parameters. The functional blocks and design of the layout may be hierarchical in nature. The signal route estimation may be based on control factors such as the specification of signal route establishment algorithms. The next step is to foliate the nodes followed by determining resistance and capacitance values corresponding to all or parts of the estimated signal routes.

  • Patent number: 6532580
    Abstract: A method and system for inserting in-place interconnect repeaters along the paths of interconnects of an integrated circuit is presented. The integrated circuit includes an interconnect layer on which an interconnect is routed, a silicon layer in which repeaters are implemented, and zero or more intervening layers. In accordance with the invention, reserved metal areas are defined on each intervening layer that resides between the interconnect layer and the repeater layer. Each interconnect net that requires a repeater for performance reasons is assigned to a repeater location. A repeater buffer is inserted at the assigned repeater locations. The interconnect net is cut into first and second subnets, which are then respectively connected through the reserved metal areas of the intervening layers to the respective input and output port of the repeater buffer.
