@ChristophZ: I was giggling constantely remembering the many many hours sitting in front of the computer moving around stupid lines with dump tools.

When I started out in the early 1980s, you didn't even have the ability to *move* tracks -- you could  place vias and you could use the digitizer to add track segments -- but all you could do was *add* or *delete* things -- we dreamed of being aboe to *move* things LOL

I have to tell you that the one thing that really took my breath away is something called

During watching this videos I kept my breath but the only thing I was able to do was constantly giggle. You look at it, it's so simple so intuitive (sorry to use this word) it feels smart. And I was giggling constantely remembering the many many hours sitting in front of the computer moving around stupid lines with dump tools.

@zeeglen: Pretty cool how it keeps differential pairs together right up to the end of the run.

The EDA tools available to us these days (both front- and back-end) simply blow me away. When you think about the raw computation involved in dynamically moving tracks and vias around -- mind-boggling is all I can say.

Also the way in which it wraps/bends the ends of the differential pair tracks around the pads and vias to fine-tune the lengths and phases.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
