CCT post-layout simulation process in mobile phone product design

In Server industry, simulation process is usually separated into pre-layout and post-layout phases. The pre-layout simulation focuses on finding the solution space or choosing a better topology. For post-layout simulation, Intel Channel Check Tool (CCT) methodology has become popular and widely used for past two or three years. CCT is the board-level interconnect electrical performance characterization method. It simplifies and automates the electrical layout checking flow without losing confidence level, and provides indicators (SIG, ISI, XTK, P_Eye, P_Ratio) for a board designer to find the potential layout issues. Comparing with server product, CCT post-layout simulation method is even more suitable for modern mobile phone design due to its routings simplicity and small board size. It is also used in feasibility study of PCB cost reduction.
