What is wrong with scalable transistors?

[Alexandre Rusev]

Why scalable transistors of MOCMOS tech are breaking LVS ?

[Steven Rubin]

The scalable transistors were an experiment that were never supposed to be in normal use. The idea was that a parameter to the parent cell would be used by this node to adjust its size. It wasn't as useful as it could have been, but it was never abandoned.

Unfortunately, transistors are handled specially in Electric, and the scalable ones don't fit in many of the normal rules, so things break. I fixed one problem where DRC was getting confused. But the way forward is simply to stop using them.
