  • Patent number: 8667450
    Abstract: A method and system for validating integrated circuit designs that are built with encrypted silicon IP blocks decrypts the encrypted silicon IP blocks in the integrated circuit designs with the keys from IP providers. After decryption, various validation checks on the integrated circuit designs are done, such as design rule check (DRC), layout versus schematic (LVS) check, parasitic resistor capacitor (RC) extraction, circuit simulation, signal electro migration (EM) and voltage drop check, signal integrity (SI) check and static timing check, etc. After validation, any confidential data from the checking results related to the encrypted silicon IP blocks are themselves encrypted to protect the proprietary silicon IP blocks. The method and system work with silicon IP encryption technology to establish a low cost silicon IP usage and verification platform, and to enable a more cost efficient silicon IP business model.

  • Patent number: 8117661
    Abstract: A method and system for protecting silicon IPs from unauthorized use, transfer and sale, and for hiding confidential technology information contained in silicon IPs is described. The method and system create a content-encrypted silicon IP layout database from its original layout database. Both the layout database may be GDSII files, OASIS files, or other format layout database file, in which multiple records sequentially build the layout database. In accordance with one preferred embodiment, first, the original layout database is parsed and saved as sequential records in the memory. Next, the structure records, which construct structures in the original layout database, are selected from the saved records. Once the structure records have been selected, the data of the structure records may be compressed with using a public compressing method, and may be encrypted with using a public cryptography algorithm.

  • Publication number: 20110091507
    Abstract: No effective vaccine exists for the devastating parasitic disease of Schistosomiasis. The present invention focuses on Sm-p80, a functionally important antigen of Schistosoma mansoni that plays a pivotal role in the schistosome immune evasion process. When used in a novel vaccine formulation, Sm-p80 demonstrates consistent immunogenicity, protective potential, and antifecundity effects. Two novel DNA constructs were made for immunization purposes. Sm-p80 coding sequence was cloned into VR 1020. Additionally, Sm-p80 coding sequence was cloned into pcDNA3.1 with flanking CpG motifs on each end of the Sm-p80 sequence. When used in different vaccine formulations, both of the constructs demonstrate the superior antifecundity and anti-worm effects of Sm-p80, which has great potential as an important vaccine candidate for the reduction of the morbidity associated with schistosome infection.
