Place an instance of each layout in a library into a cellView

examples 

CCFplaceAllInstances(?libName "stdcellLib" ?viewName "layout" ?columns 20
   ?spacing 2.0)
CCFplaceAllInstances(?cv cvId ?libName "stdcellLib" ?spacing 4.0)

I am trying out this code and getting an error that says argument missing

If you provide the actual error message, there's a chance that I might be able to help you. Without that I have no idea if there's something wrong with the code, or something wrong with how you've entered the code, or something wrong with what you're doing.

Please also provide the sub-version of the IC tools you're using (what Help->About shows).

This is error message showing:

*Error* CCFplaceAllInstances: extra arguments or keyword missing - ("ibm" "layout" "20" "2.0")
<<< Stack Trace >>>
CCFplaceAllInstances("ibm" "layout" "20" "2.0")
(... in leHiCreateInst ...)
leHiCreateInst()

version being: CADVM18.1-64b.500.10

This is how the function call was made:

CCFplaceAllInstances("lib_name" "layout" 20 2.0)

It's defined as a keyword argument function, and so you can't pass positional arguments. You'd need to do:

CCFplaceAllInstances(?libName "ibm" ?viewName "layout" ?columns 20 ?spacing 2.0)

(as shown in the comments at the top of the code). Missing out the ?libName, ?viewName etc keywords won't work.

Thanks a lot!
