  • Patent number: 10540464
    Abstract: The present embodiments relate to critical path aware voltage drop analysis. A method can include identifying a number of cell instances with largest individual power consumption values. The method can include identifying, by performing static timing analysis, a first number of circuit timing paths of an integrated circuit design with largest timing violations. The method can include identifying, by performing the static timing analysis, a second number of circuit timing paths of the integrated circuit design. Each of the second number of circuit timing paths has a timing violation and is formed by one or more of the identified number of cell instances. The method can include generating logic state toggle vectors by propagating logic states through the first and second numbers of circuit timing paths. The method can include performing voltage drop analysis on the integrated circuit design using the generated logic state toggle vectors.

  • Patent number: 10460055
    Abstract: A computer performing a transient vectorless power analysis of a multi-clock domain integrated circuit (IC) design may execute a scheduling cycle based on the dominant clock frequency and schedule events based on comparing instance clock frequencies with the dominant clock frequency. If the instance clock frequency matches the dominant clock frequency, the computer may schedule a single event per scheduling cycle for the sequential circuit devices driven by the respective instance clocks. If the instance clock frequency is faster than the dominant clock frequency, the computer may schedule number of events per scheduling cycle based on the ratio of the instance clock frequency to the dominant clock frequency. If the instance clock frequency is less than the dominant clock frequency, the computer may schedule a single event per scheduling cycle if the computer determines that there is a triggering edge of the instance clock within the scheduling cycle.

  • Patent number: 10387595
    Abstract: Disclosed herein are embodiments of systems and methods for a deterministic modeling of integrated clock gate (ICG) activity in a vectorless power analysis of a synthesized integrated circuit (IC) design. The systems and methods may generate a priority list of the ICGs based on the slack values of the outputs of the ICGs calculated from a static timing analysis (STA). The system and method may further receive one or more priority inputs from the user and select the ICGs to be activated during power analysis based on the priority list and the priority inputs from the user. The systems and methods may propagate a set of state stimuli through the output cones of the selected ICGs and calculate the current through and power consumed by circuit devices in the output cones based on the state propagation and global data activity.
