It is not as easy as Allegro but you can do it. Go to your settings and use Blaze Router.

Go to Setup-Design rules-net- select a net -High speed and now see the parameters to be defined to obtaine a delay tune.

hi raj

delay tune is mostly for matching the two signal ...or trace

hi sir


normal line and delay tune is what different is using any board

hi raj,

Delay tune routing is used to matching the timing ( negative and positive end timing) like differential pairs.

There is a way to do Serpentine routing in PADS which is pretty effective. I call it "Poor Man's Auto Router ".. You need to do some mathematics in calculating the trace lengthy required to cater to the delay requirement (approximately 120pS per inch delay on FR-4). Divide the resultant length into the number of serpentine segments that you can accommodate in your PCB (say 8 segments, 10, 12 and so on). Route one segment in PADS, and Copy paste the same thing (Ctrl C.Ctrl V) the number of times you want the serpentine to repeat. This works perfectly fine and you have tight control on routing also. I have tried this method and it has worked well for me
