Hello
I want to know about the Rev F07 net length.
I found and downloaded Rev B net length document. is there any differences between Rev B and Rev F net length?
I'm working with high Speed ADC and DAC (200MSPS) and I really need it.
Thanks

@xzsawq21 -- did you include the internal Zynq package delays?

No, you mean you have tuned the length subject to the Zynq package delays? I think it's important for above 500MHz.
I have used your length document to tune the lengths in my carrier board.
I'd would be grateful if you had any idea. :)
Thanks
The MicroZed PCB routes were originally tuned for the 7010 device in the CLG400 package. At the time of the MicroZed design, the specifications were very tight, especially in the case of the DDR3, which runs at 533 MHz. The specification was later extended to account for memory speed grade, which allowed us also to support the 7020 without changing the PCB. Several other interfaces were also tuned, all including the internal package delays.
