Signaling margin oriented LPDDR PDN design with SIPI synthesis methodology

Abstract

Signal margin oriented SIPI analytical synthesis methodology is developed for PI design with concurrence of SI design based upon PDA for LPDDR interfaces. The SIPI analytical synthesis results are well correlated with empirical Spice simulation results with circuit netlist for current and voltage waveforms, and also with lab measurements for singling margins on a particular platform with LPDDR3. Consequently, global cost competitive PDNs and optimal SI channel are achievable simultaneously with SIPI synthesis methodology for all LPDDR technologies with increasing data rate.
