本文探讨了DDR作为复杂系统中关键组件的重要性，强调了其配置（如控制器、DFI、PHY、定时、等级和能力）及测试覆盖率（包括缓存性、位宽、缓存大小、写回策略、多级缓存满时行为、秩数、锁类型、MMU启用状态、页表初始化等）的考虑。

1. DDR is the most important component for complication so that the configuration and test coverage should be considered.

config: controller/DFI/phy

timing, rank and capablity

test coverage: cachability (inner cachable/outter cachable), bitwidth, cached size (l2/l3), write back/write through, wb always failed on eviction if cache is full, 1 or 2 or 4 ranks, lock (spinlock), mmu enable/disable, page table init and allocation.
