- Channel 0 PHY to DUnit DQ mapping (only used if not 1-1 mapping)Range: 0-32.
+ Channel 0 PHY to DUnit DQ mapping (only used if not 1-1 mapping)Range: 0-32. Frequently
+ asked questions: Q: The DQS (strobes) need to go with the corresponding byte lanes
+ on the DDR module. Are the DQS being swapped around as well? Ans: Yes, DQ strobes
+ need to follow the DQ byte lane they correspond too. So for example if you have
+ DQ[7:0] swapped with DQ[15:8], DQS0 pair also need to be swapped with DQS1 pair.
+ Also, the spreadsheet used for Amenia is essentially a swizzle value lookup that
+ specifies what DRAM DQ bit a particular SoC DQ bit is connected to. Some confusion
+ can arrise from the fact that the indexes to the array do not necessarily map 1:1
+ to an SoC DQ pin. For example, the CH0 array at index 0 maps to SoC DQB8. The value
+ of 9 at index 0 tells us that SoC DQB8 is connected to DRAM DQA9. Q: The PDG indicates
+ a 2 physical channels need to be stuffed and operated together. Are the CHx_A and
+ CHx_B physical channels operated in tandem or completely separate? If separate,
+ why requirement of pairing them? Ans: We have 2 PHY instances on the SoC each supporting
+ up to 2 x32 LP4 channels. If you have 4 channels both PHYs are active, but if you
+ have 2 channels in order to power gate one PHY, those two channel populated must
+ be on one PHY instance. So yes all channels are independent of each other, but
+ there are some restrictions on how they need to be populated. Q: How is it that
+ an LPDDR4 device is identified as having a x16 width when all 32-bits are used
+ at the same time with a single chip select? That's effectively a x32 device. Ans:LPDDR4
+ DRAM devices are x16. Each die has 2 x16 devices on them. To make a x32 channel
+ the CS of the two devices in the same die are connected together to make a single
+ rank of one x32 channel (SDP). The second die in the DDP package makes the second rank.
