Channel quality comparison for OOGIO bus designs

Abstract

Traditionally, Intel supports ODM/OEM (original design manufacturer / original equipment manufacturer) IO bus designs via PDG (platform design guide). If IO bus design is out of PDG guidelines (OOG), usually Intel cannot support it. However, Intel is experiencing overwhelming customer requests for OOG support since more and more customers are designing products OOG for cost vs. performance trade-off. On the other hand, OEMs/ODMs usually have very stringent schedules and limited SI resources, and it is not practical for them to follow Intel's internal complicated SI simulation process for a robust platform design. Therefore, we propose a simple but very accurate and powerful approach, channel quality comparison (CQC), to address this problem. CQC can significantly improve Intel OOG support quality and enable OEMs/ODMs to support all OOG designs. CQC also helps them to optimize PCB Design BOM cost vs. performance and reduce product development cycle for time-to-market (TTM).
