  • Patent number: 11568116
    Abstract: A true random metastable flip-flop (TRMFF) compiler generates an electrical architecture for a TRMFF chain. The compiler selects components for the TRMFF chain from a library of standard cells and logically connects these components in accordance with a primitive polynomial to generate the electrical architecture. The TRMFF chain provides a sequence of random numbers from one or more physical processes in accordance with the primitive polynomial. During operation, one or more microscopic phenomena inside and/or outside of the TRMFF chain can cause one or more low-level, statistically random entropy noise signals to be present within the TRMFF chain. The TRMFF chain advantageously utilizes the one or more low-level, statistically random entropy noise signals to provide the sequence of random numbers.

  • Patent number: 10867089
    Abstract: Electronic system level (ESL) design and verification of the present disclosure is utilized to provide an electronic simulation of various loads on one or more batteries of an electronic device resulting from the electronic device performing one or more functional behaviors. Before this electronic simulation occurs, the electronic device is modeled using the high-level software language or the high-level software format. For example, a battery discharge model, a regulator efficiency model, a power delivery network (PDN) model, or a component power model are used to model behaviors of the one or more batteries, regulator circuitry, power delivery network (PDN) circuitry, and other electronic circuits, respectively, of the electronic device.
