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. **/ UINT8 Ch0_Bit_swizzling[32]; /** Offset 0x00A8 - Ch1_Bit_swizzling Channel 1 PHY to DUnit DQ mapping (only used if not 1-1 mapping)Range: 0-32. **/ UINT8 Ch1_Bit_swizzling[32]; /** Offset 0x00C8 - Ch2_Bit_swizzling Channel 2 PHY to DUnit DQ mapping (only used if not 1-1 mapping)Range: 0-32. **/ UINT8 Ch2_Bit_swizzling[32]; /** Offset 0x00E8 - Ch3_Bit_swizzling Channel 3 PHY to DUnit DQ mapping (only used if not 1-1 mapping)Range: 0-32. **/ UINT8 Ch3_Bit_swizzling[32]; /** Offset 0x0108 - MsgLevelMask 32 bits used to mask out debug messages.
