What changed: You can now enter any target impedance for a differential pair instead of picking from the two values in the dropdown. Quilter also no longer forces differential impedance to equal exactly twice the single-ended impedance, so you can set, for example, a 50 ohm single-ended alongside a 90 ohm differential impedance.
Why it matters: Differential impedance is a complex need driven by design factors, and the previous two-option dropdown didn't cover all values a user might want. Quilter solves for the trace geometry that hits whatever target you enter, using the Simbeor solver.
Where it is: In the Differential Pair section of the Comprehensions page
Floorplan Page [BETA]
What changed: There's a new Floorplan page, and the Placement Options section that used to live under Fabricator Constraints has been relocated to it.
Why it matters: The page exists to make Quilter's placement behavior explicit before you submit. The most common setup mistake we see is users who haven't floorplanned or pre-placed the components that need to be in a fixed position, then get surprised by Quilter’s actions. Surfacing placement intent up front prevents that from happening.
Where it is: In the usual setup flow, after Fabricator Constraints.
Note: This is only the first iteration of the Floorplan page; more changes including better visual explanations and interactivity will come soon.
Support for Schematics from Cadence
What changed: Quilter can now parse Cadence schematics alongside the board file, both generated by the Cadence export script. The full set of files Quilter now wants from Cadence is XML, QLT, DSN (the schematic), and BRD.
Why it matters: Several of Quilter's smarter behaviors, including bypass capacitor assignment and placement grouping, depend on having the schematic. Cadence users should see those improve now that the schematic comes through.
Where it is: Behind the scenes for people who upload files from Cadence.
Easily Find Any Unrouted Nets
What changed: Any nets that failed to route now appear as a review item in the right sidebar (Design Review) of the candidate reviewer, below the other DRC review items.
Why it matters: Users have asked for this for a while. Until now the only way to spot what didn't route was to hunt through the airwires. Surfacing unrouted nets directly makes it fast to see exactly what's left, whether that's a few trivial signals to finish by hand or a sign the constraints need adjusting.
Where it is: The right sidebar of the candidate reviewer.
Quilter can now calculate impedance profiles for differential pairs and single-ended impedance-controlled signals across all layers of your board, based on your stackup materials. Give Quilter any stackup on any board, and it will route using the trace widths and clearances needed to hit your target impedance.
The calculations are powered by Simbeor by Simberian, the industry-standard solver. If you’ve used impedance calculations in Altium, you’ve already used this solver. As long as the material properties in your stackup are correct, the impedance profiles will be correct.
Projects: Organized Iteration by Design
Jobs now belong to projects. A project groups every iteration of a single design (different board outlines, stackups, floor plans) into one place, so you can track your progress and pick up where you left off.
How it works: Create a new project from the home screen and upload your first job. From there, you can add as many jobs as you need, as long as each upload stays within 10% of the original BOM. Changes beyond 10% start a new project.
Why this matters: Most Quilter customers iterate 2 to 4 times on a design before going to fab. Projects make that workflow explicit: one design, unlimited iteration, everything in one place. This structure also lays the groundwork for faster solve times on subsequent iterations within the same project.
Previously submitted jobs are still accessible from your jobs list. Going forward, all new jobs require a project.
