Estimates of the peak power dissipation and the peak current are required in the design of reliable VLSI circuits. The peak current current drawn by a digital filter is dependent on the filter coefficients and the inputs to the multipliers in the filter. This input dependence makes the estimation of peak current for a digital filter a hard problem. We present a technique to estimate the maximum current drawn by a digital filter. The approach consists of: (1) building peak current macro-models for multipliers in terms of the input data transitions and the coefficient, and (2) using these models in a graph based formulation for finding the peak current of the digital filter. The peak current macro-models for multipliers are validated by comparisons with SPICE simulations. We also present the application of the technique for estimating the peak current of digital filters in a 51.84 Mb/s 16-CAP receiver. |
