How to Create Differential pair in Schematic: Differential Routing & Length Tuning

In this video, we will be covering how to create 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁𝗶𝗮𝗹 𝗽𝗮𝗶𝗿𝘀 in schematic and what exactly we mean by length tuning why we would need our board to be differential routed or length tuned, what are high-speed signals how we can avoid cross-talk, and what is balance topology.
𝗞𝗲𝘆𝗽𝗼𝗶𝗻𝘁:
Try to keep track as close together as possible and place the vias equally from the pads that they are routing from. Inner layer routing is preferable to minimize crosstalk, but that means transitioning through the layers with vias. Keep the diff pairs isolated from other traces.
The spacing between two differential pairs should be proportional to the spacing between each trace in the pair.
The spacing between two differential pairs should be in some way proportional to the distance between each pair and its reference plane.
