[FRC Blog] myRIO Expansion Port - What's the Deal?

[SoftwareBug2.0]

Maybe this is a stupid question but why do I need to use a SPICE simulation to figure out what the ports are doing? Why can't I just have a table with drive strengths and speeds and such?

And why do they assume that your circuit will be flat on the roborio and tell you clearances for stuff under where they think your PCB will be? Can't they just let you figure it out from the mechanical drawings?

I feel like a ton of effort has been put into this for no reason.
