Hi
1) Which signals should I consider for SI analysis simulation between DDR3L and AM4376
2) DDR3L - part number specs are- 256Mb depth, 16 bit, 512MB size, 1.25ns, and CL-tRCD-tRP is 11-11-11
3) What is maximum clock speed and I/O Bus speed of DDR3L-1600 RAM?
4) Processor - AM4376BZDN100
Please reply
if any document pls share.
Thanks
What are single-ended signals and differential signals?
Is all Clock signals are differential signals
what about impedances ?

Our board has one DDR3L device part number is - IS43TR16256AL-125KBL, DDR3L-1600 , 1.35V
We have designed the PCB layout as per reference board and copied the same layout on our Board ( IDK board)
But our board is 8 layer whereas reference board is 6 layer
in that case , do we need to run the simulation?
if yes, how to select the model selector from the following file

Which ODT model should we select? out of Full and Weak ODT model
120 ohm ODT model
60 ohm ODT model
30 ohm and 20 ohm model
what is selector_11 and selector_12 , what criteria should we applied to select model
The wiki link I posted is quite specific about ODT termination:
SDRAM_CONFIG.DDR_TERM (these values should correspond to DDR datasheet)
Set to 0 to disable termination.
For DDR3
1 = RZQ/4
2 = RZQ/2
3 = RZQ/6
4 = RZQ/12
5 = RZQ/8
RZQ is the 240 Ohm ZQ resistor connected to the DDR3 memory.
It will depend on what you program in the ioctrl and ODT registers for each of those signals. See register EMIF_SDRAM_CONFIG_EXT for more explanation. You can configure half or full thevinin load, and then in the ioctrl register, you can configure drive strength for each of the DDR signals.

Hi,
From below model, how to select IBIS model for our program
Could you please share IDK board IBIS model used for simulation
What files used for IDK board simulation
How to select from the follwoing and which?
