Question

Is there a way in Allegro PCB editor version 17.4 or 17.2 that I can have an impedance call-out shown in the database? In one of our designs we had setup a impedance chart which is basically dumb text. If something in the design changes the dumb chart is not automatically changed. Our designers need to remember to edit the text within the chart. Similar to the drill chart when you add or delete vias or drills the drill chart automatically changes when you bring in the new drill chart.

 

Solution

Your team may be able to use the Impedance Analysis workflow to get the differential impedance. You can export the table to a .csv file.

 

 

 

With the exported .csv file you may be able to clean that up a bit and import the data with the Add > Text command and specify the text file as the input.
