I am having issue to instantiate a mos device. The skill and python code below. I am getting RuntimeError:(dbCreateInstByMasterName" 0 t nil ("Error dbCreateInstByMasterName: Invalid origin" ((0.0 0.0))))

Skill dbCreateInstByMasterName(cv "basic" "nand2" "symbol" "inst1" list(0 0) "R0" 1)

Python `` ws=Workspace.open()

create nand cell view in basic lib.

i=ws.open_cell_view_by_type("basic","nand2","schematic") cell_view=ws.db.open_cell_view("basic","nand2","schematic")

instantiate a mosfet in nand2

ist=ws.db.create_inst_by_master_name(cell_view,"basic","pmos","symbol","M0",[[0.0,0.0]],"R0",1) ``

You put double braces around the origin. [[0.0, 0.0]] creates a list with a single element which is the origin. But you want a flat list of x/y coordinates: [0.0, 0.0]

ws.db.create_inst_by_master_name(cell_view, "basic", "pmos", "symbol", "M0", [0.0, 0.0], "R0", 1)

I tried with the single bracket, its giving another warning Skill response:0: UserWarning: (DB-270330): dbCreateInstByMasterName: cellview recursion detected. :(

Edit: working now. Thanks
