A measurement error on a gate is defined to quantify the discrepancy resulting from replacing the size required by a synthesis sizing algorithm with a size available in a discrete cell library. The criterion for gate size selection is a set of gate sizes that minimizes the cumulative error of a prescribed measurement. Optimal solutions to the gate size selection problem targetting size and delay measurements are presented for cases when the probability distribution and the delay equations are simple. A realistic probability distribution is obtained using a sample space of gates derived from a group of designs that is synthesized under the semi-custom synthesis methodology (K. Shepard et al., 1997). A \"delay match\" (minimizing delay error) and a \"size match\" (minimizing size error) set of gate sizes are obtained numerically and are subsequently realized as discrete cell libraries. The previous group of designs are synthesized using the two selected cell libraries and two other cell libraries, one with \"equal spacing\" of cell sizes and the other with \"exponential spacing\" of cell sizes. The \"size match\" library gives the best overall slack and area results.","PeriodicalId":224802,"journal":{"name":"1998 IEEE/ACM International Conference on Computer-Aided Design.

Undesired perturbations, i.e. noise, in practical electronic systems adversely affect the spectral and timing properties of oscillators resulting in phase noise, which is a key performance limiting factor, being a major contributor to bit-error-rate (BER) of RF communication systems, and creating synchronization problems in clocked and sampled data systems. We first present a theory and numerical methods for nonlinear perturbation and noise analysis of oscillators described by a system of differential algebraic equations (DAEs), which extends our recent results on perturbation analysis of autonomous ordinary differential equations (ODEs). In developing the above theory, we rely on novel results we establish for linear periodically time varying (LPTV) systems: Floquet theory for DAEs. We then use this nonlinear perturbation analysis to derive the stochastic characterization, including the resulting oscillator spectrum, of phase noise in oscillators due to colored (e.g., 1/f noise), as opposed to white noise sources. The case of white noise sources has already been treated by us in a recent publication (A. Demir et al., 1998). The results of the theory developed in this work enabled us to implement a rigorous and effective analysis and design tool in a circuit simulator for low phase noise oscillator design.","PeriodicalId":224802,"journal":{"name":"1998 IEEE/ACM International Conference on Computer-Aided Design.
