Patents by Inventor William Eklow

William Eklow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8935583
    Abstract: A method to perform component testing by supplying test patterns to a serial input pin coupled to an IEEE 1149.6 boundary-scan cell that is associated with an IEEE 1149.6 test receiver. The test receiver is configured to operate in a scan test mode. The output from the test receiver circuit is coupled to a logic block to be scan tested. The output from the logic block is coupled to a serial output pin on the integrated circuit during scan test mode. High performance integrated circuits can use SerDes pins in a scan test mode to be scan tested without impacting mission critical signals.
    Type: Grant

  • Patent number: 7543208
    Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for providing a JTAG to system bus interface for accessing embedded analysis system(s). JTAG commands are received and converted into commands sent out a bus to a device including an embedded analysis instrument, with results received over the bus forwarded out the JTAG interface to an external device. Such a JTAG to system bus interface may eliminate the need to provide separate JTAG TAP interfaces on each ASIC of a board, and/or eliminate the need to daisy chain multiple TAP interfaces of multiple ASICs in order to provide a single TAP interface for accessing the multiple embedded testing instruments.
