Solution
The way to modify the trace properties is using the
Spreadsheet View in Ultiboard. Follow the steps below to modify the trace length.
- Open the Spreadsheet View.
- Navigate to the Nets tab in the Spreadsheet View. Look for the Net that you want to modify.
- Determine the minimum routing length from the origin of the net to the destination by routing manually a starter trace. Then, you can remove or delete this trace.
- Set the Topology of interest to Star for the traces you need to modify/match. This should change the Max Length and Min Length from N/A to a number. Change the Min and Max Lengths. The Min length has to be at least the value of your started trace from step 3.

- You can use the Autorouter Tool in the Autorouter Menu, to automatically create the traces and this will generate traces. Tip: Go to the Autorouter/place options and set the Routing mode to Gridless, this will give the router flexibility to go off-grid and match lengths.
