  • Abstract
    This paper describes circuit and packaging design challenges encountered while attempting to optimize the source synchronous timing equations for the system level interconnects using a 200 MHz double data rate (DDR) level 3 (L3) cache subsystem. Various solutions to these challenges are presented. The delay skew budget and noise margin allocation for the various components of the optimization equations are discussed in conjunction with their associated delay skew control techniques
