我共享一个四边形的吧,原理就是先画一圈,然后进行for循环画出其他边。LIBRARY = "master"
CELL = "myInductor"
LAYER = "metal2"
pcDefinePCell(
list( ddGetObj(LIBRARY) CELL "layout" )
;- Define Formal Parameters:
(
(indLayer LAYER )
(indLengthX 130.0 )
(indLengthY 120.0 )
(indWidth 8.0 )
(indGap 7.0 )
(indSeg 12 )
)
;- Define local variables of this cellview:
let(
(
indPath indPoints i j tmpPt pt
indSpacing
totalLength
pt1 pt2 pt3 pt4 pt5
)
indSpacing = indWidth + indGap
;- First five points for four outer loop segments.
pt1 = list( 0 -(indWidth/2) )
pt2 = list( 0 indLengthY )
pt3 = list( indLengthX indLengthY )
pt4 = list( indLengthX 0 )
pt5 = list( rodPointX(pt1)+indSpacing 0 )
indPoints = list( pt1 pt2 pt3 pt4 pt5 )
;- Rest of the points just follow the conditions.
;- It could've been written the same way for all the points.
;- But, that will make following equations look more complex.
;- For inner loop segments.
for( i 5 indSeg
j=mod(i 4) ;- Modulus of Segment Number and 4
pt = nth( i-4 indPoints ) ;- Dependency point.
case( j
(0
tmpPt = list(
rodPointX( pt ) + indSpacing
rodPointY( pt ) + indSpacing
)
)
(1
tmpPt = list(
rodPointX( pt ) + indSpacing
rodPointY( pt ) - indSpacing
)
)
(2
tmpPt = list(
rodPointX( pt ) - indSpacing
rodPointY( pt ) - indSpacing
)
)
(3
tmpPt = list(
rodPointX( pt ) - indSpacing
rodPointY( pt ) + indSpacing
)
)
)
;- Append new point (tmpPt) to point list ( indPoints ).
indPoints = append1( indPoints tmpPt )
)
;- Define inductor:
indPath = rodCreatePath(
?cvId pcCellView
?layer list( indLayer "drawing" )
?width indWidth
?pts indPoints
?endType "variable"
?endExt indWidth / 2
)
;- Create reference labels (length, width, cap value):
dbCreateLabel(
pcCellView
list( "text" "drawing" )
( indPath~>centerCenter )
sprintf(nil "\nX = %L \nY = %L" /* \nL = %L */
indLengthX indLengthY) /* totalLength */
"centerCenter"
"R0"
"stick"
4.0
)
); let
); pcDefinePcell
