A PCB trace length analyzer for KiCad boards. Reads a .kicadpcb`, finds the interfaces on it -- DDR, Ethernet, USB, PCIe, MIPI, SD and any differential pair -- measures how far each net is from the length it should be, and says what to do about each one: match it where it is, open some room beside it, or route it to a given length instead.
It can also fold the meanders in for you. That half is opt-in and experimental; the analysis is the product.

Pcb trace length analyzer: common questions
What microcontroller does the Pcb trace length analyzer use?
The Pcb trace length analyzer is built around the STM32MP257FAI3, from the STM32 family.
How big is the Pcb trace length analyzer?
The Pcb trace length analyzer measures 100 × 100 mm, has 6 copper layers and is 1.614 mm thick.
How many components are on the Pcb trace length analyzer?
364 components, from 64 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pcb trace length analyzer design files?
From the embeddedci-com/pcb-trace-length-analyzer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pcb trace length analyzer design in my own project?
The repository has no license, so all rights stay with embeddedci-com. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pcb trace length analyzer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
