Layout fill with dummy decoupling caps (poly1, M1, ...) for noise reduction and EMC

May be the UniFill program from might achieve this. Try and ask them.
 
I do this almost all the time, but by hand (I do my own layouts
and every cell's white spaces I fill with plates - why not?). The
final fill usually also involves manual placement of density fills
(where there's no bussing to decouple) or plate cells (where
useful). There had better be more to the patent than the idea
of the parallel plate capacitor, because that's been around for
a year or two.

Back in the day we had CAD scripts to fill spaces with dummy
islands. But you would need the script to hook up these caps
to make them useful, and that would be trickier.

I'm just not that big a fan of automating everything. But then I
also have no interest in megagate stuff.

Me to, since 10 years at least, mostly poly-thinox to decouple Vdd or ref. voltages.

The patent covers EXT, DRC & skill scripts to achieve this fully automatic.
(But I wasn't with this company) ;-)
