Calculating copper trace lengths for controlled impedance

Former Member
Former Member over 15 years ago

It would be really nice if there was a way to simply click on a copper trace

(wire) and have it's signal name and length immediately displayed (for use

when routing impedance controlled wires).  Could you possible create a

button/tool that appears in the menu?  Or could you possibly add the length

information to the "info" dialog?  Or could a .ulp be written that does

this?  I cannot find a way to extract the current mouse X/Y coordinates when

the mouse is clicked.

 

Length.ulp does this, but it produces a lengthy text file that lists the

signal names and lengths for all wires on the board - which you then have to

manually open, find the signal name, then obtain the length for each wire

that you work with.

 

Many thanks!

    You can use length.ulp with for example two signal names.

     

    RUN length.ulp name1 name2

     

    will give a list of two signals only.
