Error during stream out

Mohannad

 Hello,

I am making a PCELL using skill. When I load the PCELL .il file through icfb window, everything works fine. I insert te cell in another layout and then try to steam out the layout to a .gds file, but I get this error:

FATAL(449): Pcell eveluation failed. This could happen as a result ofeither a syntax error or the use of an unsupported PIPO function

 I would greatly appreciate any help.

 Thank you very much

     Hi Mohannad,

    Most likely you are using a function that is not supported within PCells - it may work correctly in an interactive icfb/virtuoso session, but PIPO (or Xstream for the CI61x releases) do not include definitions for functions that are not supported within a PCell.  "What functions are supported?" you may ask - there is a section in the documentation "Safety Rules for Creating SKILL Pcells".  You should only use core SKILL functions, and those with the approved prefixes; namely db, dd, cdf, rod and tech (plus a few others).

    Hopefully this will resolve your issue (but next I expect you may be asking for equivalent functionality for the function(s) that is/are causing the issue?).

    Regards,

    Lawrence.
