About QCVS Tool DDR3L

[kojimiura]

Using QCVS
DDR3L data rate = 1200M/Ts,
tCL=9clock, tRP/tRCD=9clock
Created DDR parameters.
Although OBC_CFG='1',
WRTORD becomes 5
It has become.
In the reference manual
I think it has to be tWRT+2, so
7.5ns (=5CK) + 2 from DDR3L timing
I think 7 is the correct answer, what do you think?
Attach the generated tcl file.
Thank you.

Thank you for your response. In QCVS Since OBC_CFG='1' This is burst chop mode. I believe that 5+2=7 is the correct answer.

The configuration of QCVS is correct, it is fine to configure WRTORD field as 5.

As for the 2 additional cycles to this field, it's the controller requirement in burst chop mode to add the 2 additional cycles.
