  • Patent number: 11605583
    Abstract: An integrated circuit package includes a transmission line structure, wire bonds, a first post and a second post. The transmission line structure runs from a printed circuit board (PCB) to an integrated circuit (IC) and includes a center transmission line between two ground lines and sealed from exposure to air. The wire bonds connect the transmission line structure to pads on the integrated circuit from where the center transmission line exits the integrated circuit package. The wire bonds are selected to have an impedance matched to impedance of the integrated circuit. The first post supports the center transmission line where the center transmission line enters the integrated circuit package from the printed circuit board. The second post supports the center transmission line where the center transmission line exits the integrated circuit package to connect to the wire bonds.

  • Patent number: 11257771
    Abstract: An integrated circuit package includes a transmission line structure, conductive bonds, a post and a dielectric post. The transmission line structure runs from a printed circuit board (PCB) to an integrated circuit (IC) and includes a center transmission line surrounded by ground and sealed from exposure to air. The conductive bonds connect the transmission line structure to pads on the integrated circuit from where the center transmission line exits the integrated circuit package. The first post is part of the center transmission line where the center transmission line enters the integrated circuit package from the printed circuit board. The dielectric post supports the center transmission line where the center transmission line exits the integrated circuit package to connect to the conductive bonds and compensates part of the conductive bond inductance.

  • Publication number: 20070294071
    Abstract: A hardware accelerator includes hardware support for a combinational only cycle and a latch only cycle in a simulation model with a single partition of latches and combinational logic. Preferred embodiments use a special 4-input 1-output function unit in the hardware accelerator in place of the normal latch function that write back the old latch value for combinational only cycles. Other embodiments include hardware support for separate array write disables for arrays and transparent latches depending on whether the cycle is a combinational only cycle and a latch only cycle. A conditional array write disable dependent on the occurrence of a hardware breakpoint is also included that supports switching from a latch plus combinational cycle to a latch only cycle, to give control to the user before evaluating the combinational logic if a breakpoint occurs on a latch.

  • Patent number: 6881778
    Abstract: A polyvinyl alcohol copolymer latex composition comprises an intimate polymer composition obtained from 10% to 60% by weight of a substantially hydrolyzed low molecular weight polyvinyl alcohol (PVOH); 2% to 80% by weight of at least one diene; 2% to 80% by weight of at least one hydrophobic monomer other than a diene and optionally either up to 10% by weight of at least one hydrophilic ethylenically unsaturated acid monomer or up to 40% by weight of a cationic monomer. The copolymer latex composition can be prepared as an emulsion from an aqueous blend of the above listed monomers which are generally added at various stages during the polymerization and a free radical initiator, surfactants, and, if desirable, chain transfer agents. Up to 80% of the PVOH may be added after the monomers have been polymerized.
