Hello Folks,I would like to create a PCell for a partial torus with three parameters, outer radius, inner radius (size of hole for a complete torus) and azimuth angle (or fraction of a complete torus). Thanks from aNewbie
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/passiveLibwithin 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!Regards,Andrew.
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 ...)...Regards Elmar
