This only provides the lenghts of the signals? What about help in placing the traces?
Thanks,
DeWayne

Hi Lev and Don,

there are two ULPs that can help.
length.ulp gives a list of all signals with its total lengths or when used with for example two signal names

RUN length signal 1 signal2

it gives a list of these two signals only.
There is also length-freq-ri.ulp which gives a bit more information in the list of all signals. Try it.

Regards,
Richard

Very clever! I like it. I'm going to have to do a lot of pairs so can this be done on a large scale?

Hello Heedaf,
     I am sure there are files... but I make one trace from the pair wide as the sum of final traces + gap of the differential pair. After I finish layout, I change its width back to normal - and now there is enough room to place both traces in parallel.
    If you want to place traces in different layers (to do it you need, most probably, multilayer PCB), place one (let say, "top") trace first, keep room under it free than layout, "cut" whole trace (as "group"), "paste" trace at the empty space, change its layer to "bottom" and move it as "group" to the designated place.
    Lev.

Hi,
What is the best way to run a differential pair? Is there any tricks or files I can run to help the process out?
Thanks,
DR

Thanks Richard ... no need to send you the file as I've found the problem ... it was a case of 35 pins defined in the symbol and 34 pins in the package, due mainly (besides my oversight) to the data sheet for the part showing a NC pin in the pin list but no pad for it in the suggested footprint. Quite frustrating to find this the first time, would suggest some kind of more intelligent error message.

Regards,
Don

Panos,

please check the settings in Windows 7 Control Panel, System and click onto Advanced System settings.
There in the Advanced tab you find a button Environment Variable. Click it and check whther there is variable
LANG defined. If not please set it to en_US.
Does Designlink work then?

Regards,
Richard

Hi Panos,

no this can't be the problem. I am located in Europe as well and I can use the designlink ulp with Newark. I simply set the language setting to en_US and it works.

What is your operating system and locale settings?

Regards,
Richard
