Patents by Inventor Dhananjay Raghavan

Dhananjay Raghavan 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).

  • Publication number: 20230129176
    Abstract: A method includes mapping an aging measurement circuit (AMC) into the core fabric of an FPGA and operating the AMC for a select time period. During the select period of time, the AMC counts transition of a signal propagating through the AMC. Timing information based on the counted transitions is stored in a timing model in a memory. The timing information represents an aging characteristic of the core fabric at a time that the AMC is operated. An EDA toolchain uses the timing information in the timing model to generate a timing guard-band for the configurable IC die. The AMC is removed from the core fabric and another circuit device is mapped and fitted into the core fabric using the generated timing guard-band models. The circuit device is operated in the configurable IC die based on the timing guard-band models.

  • Patent number: 11609262
    Abstract: An integrated circuit die includes a core fabric configurable to include an aging measurement circuit and a device manager coupled to the core fabric to operate the aging measurement circuit for a select period of time. The aging measurement circuit includes a counter to count transitions of a signal propagating through the aging measurement circuit during the select period of time when the aging measurement circuit is operating. The transitions of the signal counted by the counter during the select period of time are a measure of an aging characteristic of the integrated circuit die.
