Hi. In another post I was asking about diff pair tuning.....well....I just cannot figure how to do it. I am willing to pay someone to take the brd, tune the diff pairs and send it back with detailed explanation how it was done. It HAS to be in either 16.0 or 16.5 XL
I need this done by Tuesday 6/18 LATEST.
PS This will probably be gravy for someone who knows their stuff.
You could always try using Route - Phase Tune which means you can add a small bump to each half individually to try and help meet the phase. Look at the Options menu for values for the size of the bump.
In reply to steve:
I have route-> delay tune, but that has no options for "bumps", at least in 16.0. I saw that in the doc you uploaded. Can't find it.
But anyway, I got the lengths tuned after the EE relaxed the delta from 5mil to 100mil and I fiddled with the constraint manager until I got the etch lengths to make sense. (Had a dream about them last night.......)
In reply to pitbull107:
You'd need at least 16.5 to see Phase Tune.
I would just add that updating to 16.6 with the newest quarterly incremental release would give you a prototype of the new phase tune that will be coming up in a later quarterly update.
You can see a bit of it in the movie below, although the spoken language is Danish, you could move forward to 6 minutes and get the meaning of this. My prediction is that the complete timing vision and tuning environment will make routing and understanding timing constraints so much simpler going forward.
Hope you can use it for inspiration.
