This application note explains that hardware developers using the SPEAr600 embedded MPU need to use IBIS models for signal integrity simulation on the application PCB. The selection of IBIS models depends on the register settings or the operating mode from the SPEAr600 user manual.
This document is intended for hardware developers using the SPEAr600 embedded MPU. It details the mandatory use of IBIS models to ensure PCB layout does not introduce functional problems or timing issues in high-speed interfaces like DDR2 and Ethernet.
The note provides specific instructions on selecting the correct model from the sp600_v13.ibs library by reading register settings or knowing the operating mode. It covers model selection for PL_CLK, PL_GPIO, GMAC, SMI, LVDS, and DDR interfaces.
It explains how to select the correct IBIS models from the library for signal integrity simulation of SPEAr600 applications.
The models are organized in a library named sp600_v13.ibs.
The note covers PL_CLK, PL_GPIO, GMAC, SMI, LVDS, and DDR interfaces.
