how to Add M1 drawing on pcell,only for mos?

FormerMember
FormerMember
This is the code I wrote to add a layer of M1 on the pcell, and the M1 package hole is 0.005, which meets the requirements of DRC.
But now this code will handle all instances and mosaics, such as resistors, capacitors, BJTs, etc. This is not the result I wanted. Can you help me modify it? It only needs to be processed for MOS. Thank you
procedure(AddMosM1()
let((cv objs metal1 temp shapes x y ux uy xy row column transform
M1_width)
M1_width = 0.11
cv = geGetEditCellView()
objs = geGetSelSet()
foreach(obj objs
transform = nil
if(obj~>objType == "inst" then transform = list(obj~>transform))
if(obj~>objType == "mosaic" then
x = xCoord(obj~>xy)
y = yCoord(obj~>xy)
ux = obj~>uX
uy = obj~>uY
row = obj~>rows
column = obj~>columns
for(a 0 row-1
for(b 0 column-1
case(car(obj~>tileArray)
("R0" xy = list(x+b*ux : y+a*uy))
("MXR90" xy = list(x+a*ux : y+b*uy))
("R90" xy = list(x-a*ux : y+b*uy))
("MY" xy = list(x-b*ux : y+a*uy))
("R0" xy = list(x+a*ux : y-b*uy))
("MXR90" xy = list(x+b*ux : y-a*uy))
("R0" xy = list(x-b*ux : y-a*uy))
("MXR90" xy = list(x-a*ux : y-b*uy))
) ;end case
transform = append1(transform list(car(xy) car(obj~>tileArray) 1.0))
) ;end for
) ;end for
) ;end if
shapes = obj~>master~>shapes
foreach(shape shapes
if(car(shape~>lpp) == "M1" && cadr(shape~>lpp) == "drawing" then
foreach(trans transform
metal1 = dbCopyFig(shape cv trans)
temp = leConvertPolygonToPath(metal1)
temp~>width = M1_width
) ;foreach trans
) ;if M1
) ;foreach shape
) ;foreach obj
) ;let
) ;procedure
hiSetBindKey("Layout" "ctrl<Key>v" "AddMosM1()")

    The code is hard to read because of the lack of indentation, and also it's not quite clear what your intent is, but presumably you just need to add a condition around the:

    if(obj~>objType == "inst" then transform = list(obj~>transform))
    if(obj~>objType == "mosaic" then
     
    part to check that obj~>libName and obj~>cellName correspond to one of the MOS devices you care about. Then you'd only be collecting the transforms for the relevant devices?

    For example, I need to handle several names of MOS, pch3v,pch5v,nch5v,nch3v。
    So how to modify this code?
    need to create a list?

    when(obj~>libName=="yourPDK" && member(obj~>cellName '("pch3v" "pch5v" "nch5v" "nch3v"))
      ...
    )

    or you could use a regular expression:

    when(obj~>libName=="yourPDK" && pcreMatchp("^[pn]ch" obj~>cellName)
      ...
    )

    thank you very much，best wishes.

    I try it right now.
