     @Shark@miniwa.moe As you may have already found out by now, the speed of light is too slow, so those are delay lines to ensure all signals in the same group have the exact same length so signals arrive at their destination at the same time."For example, 1% (±0.5%) at 800 MHz clock is 6.25 picosecond (1250ps/200). Typical flight times for FR4 PCB are near 6.5 ps/mm. So matching to ±1mm (±0.040 inch) allocates 1% of the clock period to route matching."

     @niconiconi those wavy looking traces look cool, for the past 10 minutes I've been trying to find out what do they do.
