QuoteIf you are able to share an email address with me privately, I would be happy to share the PDF version of this for you to add to your official documentation.
QuoteUh... I don't really understand this comment. Part of why I needed to ask in the first place is that your DRAM breakout has multiple trace geometries in it - 3.2mil for the SOC fanout, then 5 mil for the meander to the DRAM. It was hard for me to know which one was your target geometry without a trace impedance table.
I am working on making a Trace Impedance Table separately to compare your target impedances against the ones I used.
QuoteI'm so glad you pointed that out! This is the tool I'm using to check our own boards. Are you able to share any information on how to run this on the iMX8MP SOM + EVB?
