Abstract: Methods and systems for designing an integrated circuit device are described. The method includes receiving RTL descriptions of the whole device and generating lower level component descriptions. The method further includes grouping the component descriptions into blocks, analyzing the component descriptions, and identifying block internal removable components based on the analysis. The method further includes removing the removable components. Reduced design is converted into gate-level descriptions. Finally, the method includes executing high quality and high efficiency device TOP level physical implementation and generation of physical and timing constrains for block level design.

Abstract: In a method of processing a packet header received via an input interface, a plurality of data units that collectively correspond to a header of a network packet is received. A location of a target field of the header in one or more data units among the plurality of data units is specified, and the one or more data units containing the target field are identified among the plurality of data units. The target field is processed using a local offset corresponding to the specified location of the target field in the identified one or more data units, without simultaneously storing all data units of the plurality of data units in a buffer.
