DDR3 Signal length in i.MX6Q

Dear Sir or Madam,

 

Hello.

Refer to Table 3-5. Total signal etch (DDR3) in Hardware Development Guide for i.MX6DQ6SDL, Rev. 1.

There is description of DRAM_SDCLK0 : 2120.044[Mils].

 

My customer measured the DRAM_SDCLK0 length on i.MX6Q SABRE-AI.

Actually the DRAM_SDCLK0 length looked 1849.483[Mils].

Refer to attached file: "DDR3_SDCLK_Length.xlsx"

 

[Question]

Should we think including the branch wiring about each signal length?

Or, can we ignore the branch wiring length?

 

BR,

Keita
