  • Patent number: 8999752
    Abstract: An embodiment of the present invention is directed to a semiconductor packaging frame allowing identification information to be stored in the paddle area of the individual frame. Forming identification information on the paddle allows unique tracking of the semiconductor frame package during and after manufacturing and for tracking down variances, defects, and other problems during the semiconductor packaging process. Further, the shapes formed from the identification information provide increased surface area for bonding of the molding compound and thus strengthen the bond between the die paddle and molding compound thereby improving the strength of the semiconductor package.

  • Patent number: 9003346
    Abstract: Techniques for reducing post-routing delay variance are described herein. In an example embodiment, an initial netlist includes multiple instances that represent digital components of an electronic design. An base signature is assigned to each instance in the initial netlist, where the base signature is based on two or more design or connectivity attributes of the instance. The base signatures are then used to generate an initial instance ordering of the instances in the initial netlist. A subsequent netlist, different from the initial netlist but representing the same electronic design, is received. Base signatures are assigned to the instances on the subsequent netlist and a subsequent instance ordering is generated. The subsequent instance ordering preserves the same order as the initial instance ordering for those instances that are included in both the initial netlist and the subsequent netlist. In this manner, any later netlist-based processing (e.g.
