length tuning

[xzswq21]

Hello
I could tune the lengths in Altium successfully.
but I have a problem!
actually I have a SOM (a small FPGA board) and it has 200 pins totally.
I want to connect my board to the SOM. all the pairs are LVDS.
the problem is:
the tracks on the SOM are not tuned within 10mils, there is 1cm of mismatch between the pairs! 
now I have a length document (text file), how should I load the file into Altium and tune the tracks on my board to have equal lengths?



Best Regards

I assume you found the answer by now, but if not, you can use the "package length" option. This allows you to add arbitrary lengths to the signals to account for delays internal to an IC package (or SOM in your case). The lengths will be incorporated into the length tuning in the PCB layout.

Thanks for that. I wasn't aware they had introduces that feature. Last time I used Altium for a high speed design, I had to do it manually

Looking now to see what, if any, other goodies they've added
