devices() compilation error

Hi, I'm using the function devices() to use the function leChopShape, and this error is reported.  Can the function starting with le be used in devices()? 

 \o *WARNING* (DB-270001): Pcell evaluation for TECHLIB/nmos/layout has the following error(s):
\o *WARNING* (DB-270002): ("eval" 0 t nil ("*Error* eval: undefined function" leChopShape))
\o *WARNING* (DB-270003): Error kept in "errorDesc" property of the label "pcellEvalFailed" on layer/purpose "marker/error" in the submaster.

    Hi,

    No, you can't use functions that begin with the le prefix in a PCell.  The functions that can be used in a PCell start with these prefixes: tech, db, rod, dd, cdf, abe, cst, tx, some pc* functions and core SKILL functions. Check the documentation for the section called "Safety Rules for Creating SKILL Pcells" which will give more details.

    Best regards,

    Lawrence.
