Abstract

In a high speed digital integrated circuit, annex delay can be momentous and hold for factual exploration by using moments of impulse response delay exploration has been done. Elmore delay is (the first moment of impulse response) interpretation, to moment matching approach which establish reduced order trans-impedance and transfer function approximations. The elmore delay is swift becoming inadequate for deep submicron technologies and reduced order transfer function delays are un-functional for use as early phase design matrices. This paper interpret access for fitting moments of the impulse response to probability density function, so that delay can be appraisal factually for RLC trees, it is a demonstrated that inverse gamma function provides a provable stable approximation. For prolong delay matrices for ramp inputs to the more general and realistic non-step input, we use PERI (probability distribution function extension for ramp input) technology. The factual model consequence compared with MATLAB simulation.
