Application ReportSPRA839A - April 20031 Using ibis Models for Timing AnalysisC6000 Hardware ApplicationsABSTRACTT oday s high-speed interfaces require strict timings and accurate system design . To achievethe necessary timings for a given system, input/output buffer information specification ( ibis ) Models must be used. These Models accurately represent the device drivers under variousprocess conditions. Board characteristics, such as impedance, loading, length, number ofnodes, etc., affect how the device driver behaves. This application report discusses how toproperly use ibis Models to attain accurate Timing Analysis for a given system. This reportfocuses on the use of SDRAM with a TMS320C6000 DSP, but is applicable to all interfacesthat have setup and hold .. 2 Establishing a Reference Point3.. 3 Understanding the Tester5..
