PCell for a partial torus

This isn't Facebook - there's no need to tell everyone what you're currently doing ;-)

Sorry for the cheeky comment, but you didn't actually [u]ask[/u] anything! I'm assuming you'd like some example code, or something like that? Anyway, one place to look is in the Cadence IC installation:

/tools/dfII/samples/artist/passiveLib

within this library, there is a "spiralInd" pcell. If you look at spiralInd/spiralInd.s.pc you'll find the SKILL code for the pcell.

Not exactly your spec, but similar enough to borrow from, probably. Assuming that's what you wanted!

Maybe you need code for a drc right circle on multiple of manufacturing grid for rthe solution of your problem:

procedure( DrcCorrectDrawCircle(cv lpp centerx centery radius grid )
let( (ccords x y lasty yend rsq list2)
ccords='()
x=0
lasty=0.0
y=radius/grid
rsq=radius*radius/(grid*grid)
yend=radius*sqrt(2.0)*0.5/grid
while(y>yend
x=floor(sqrt(rsq-(y*y)))
ccords=cons(list(x*grid y*grid) ccords)
y=y-1.0
);while
y=grid*floor(yend)
xy45=list(y y)

list2=append(
reverse(ccords)
list(xy45))
list2=append(list2
foreach(mapcar elem ccords list(cadr(elem) car(elem))))
list2=append(list2
list(0.0:0.0) )
dbCreatePolygon(cv lpp foreach(mapcar elem list2
list(car(elem)+centerx
cadr(elem)+centery)))
)
)


in PCell code use
...
DrcCorrectDrawCircle(pcCellView list("M1" "drawing") 3.4 ...)
...
