This paper continues to build on the dynamic current transient estimation method introduced in previous work. Our previously introduced method uses pre-characterized data from standard cells to estimate the total current transient of a path. This method eliminates the necessity of running resource intensive full-chip SPICE simulations to estimate the current transient of a path. Novel contributions of this work include: estimation for multiple overlapping paths, multiple temporally distributed input transition estimation, and estimation for glitches in the logic due to dynamic hazards. Extra characterization points are also introduced which provide a considerably higher accuracy of estimation to SPICE simulations, at the cost of a slightly larger one-time investment during pre-characterization of the standard cell library. Data presented in this paper consists of current estimation of a logic path from the ISCAS-85 C6288 benchmark circuit with very promising results. |
