Code works a cds6 but not on cds5

Ok, I already found that if I change libName and cellName with another name they both pass.  Are these two restricted names?

Effectively the problem is caused by the fact that you are relying on dynamic scoping when the pcell body is evaluated. The pcDefinePCell function is an "nlambda" function, and does not evaluate its arguments before it is called - because it contains code that you want to be evaluated later. As a result of this, certain variables may be being hidden by the code inside the implementation of pcDefinePCell.

If instead you use the backquote function and then insert the values in the right place with the comma, and use eval() to evaluate the pcDefinePCell, it also works:

procedure( icsMatchedArrayUnit(libName cellName mosType l w pcDrainN)

 eval(
  `pcDefinePCell(

    ; Declare cell identifier
    list(ddGetObj(,libName) ,cellName "layout")

    ; Set pcell parameters
    (
    (Unit int 1)
    (l float ,l)
    (w float ,w)
    (pcLibName string ,car(mosType))
    (pcViewName string ,cadr(mosType))
    (pcViewType string ,caddr(mosType))
    (pcDrainN int ,pcDrainN)
    )

    ; some dummy bit of code so that Andrew can test it
    let(()
    fprintf(stderr "Unit is %L\n" Unit)
    )
  )
 )
)
