maybe someone has had any experience on the following problem:
I am searching for guidelines on measuring data lines, strobe lines, control lines between DDR SDRAM and user FPGAs (DDR SDRAM controller) on the board but unfortunately I have not found such information yet.
I would like to know what I have to take into account when trying to measure with an oscilloscope the different data lines so that data integrity is not negatively affected.
Are there any layout guidelines/examples/papers for adding measuring points (for example approach with coaxial connectors) to the DDR lines ?
What bandwidths do you recommend for oscilloscopes when measuring phases between DQ and DQS for 133MHz reliably?
Thank you for your help in advance.
