Altium Net Length

Hi is anyone here knows how to deal with PCB Net lengths in Altium
Designer?
BTW, i'm currently routing 2-DDR2 device, so i have to match the length
of the two DDR net length.

Thanks.

 

yy7d6,
Are you having problems with the net length matching function or you
don't know about it?

Contary to intuitive thought, the net length matching function must be
run repetitively until the lengths have been matched within your tolerances.
It doesn't run one single time and achieve the matched length in that one
pass.

If your question is as basic as it may appear, try reading the PDF files
supplied along with the help files under the Help menu. The PDFs should have
some guidance on the function itself or it may come under their instruction
for autorouting and DRC rules generation/definition for net lengths.

p.s. I don't currently use AD so I can't give you specific instruction on
using it.
