Sujit, Your 50ohm rising and falling waveforms are not switching sufficiently. Your driver is too weak, so you may have to boost your minimum load. - April --------------------------------------------------- April Hachenburg Core Technology Design Engineer SMSC - Phoenix Sujit Kumar-r65837 <sujit@freescale.com> Sent by: owner-ibis-users@server.eda.org 01/25/2007 06:58 AM To ibis-users@server.eda.org cc Subject [IBIS-Users] ibschk- warnings hi ibis experts ibschk run on an ibis generates following warnings: IBISCHK4 V4.0.2 Checking ddr.ibs for IBIS 4.0 Compatibility...
