AM3352: AM335X

Part Number: AM3352


你好!

主芯片:AM3352BZCZA80

问题:

在阅读手册及相关文档时,里面提到DDR3的时序不需要计算,只要严格遵守DDR3的布线规则即可,无需IBIS模型仿真。

For the mDDR(LPDDR), DDR2, DDR3, DDR3L memory interface, it is not necessary to use the IBIS models to analyze timing characteristics.

These rules, when followed, result in a reliable DDR3 memory system without the need for a complex timing closure process.

我想问:

1:针对不同的DDR3芯片,同一套布局布线规则是如何确保timing的准确?

2:AM3352没有DDR3的timing数据吗?

3:DDR3的时序是不需要计算吗?

4:如果要计算,需要计算哪些时序?参数从哪里获取?

以上,谢谢!
