Placing an instance with scaling.

Jfer2u

In 6.1.6 how do you place an instance with a reduced scaling?  This used to be an option but I can't find it anywhere in the pulldown menus.

    You can use dbCreateXformPCell() to create yourself a pcell which gives you a parameter to set the magnitude (and angle) of the shapes within the pcell. This is described in http://community.cadence.com/cadence_technology_forums/f/48/p/21611/1308026#1308026

    Essentially what you'd do is open the cellView you want to create a scaling pcell for in the layout editor, and then in the CIW type:

    dbCreateXformPCell(geGetEditCellView() "libNameYouWantThePCellIn")

    and it will create a cellView in that library with the same cellName as the original, but with a view "layout_xform".

    Note that you shouldn't use this with anything with a huge amount of contents, as it has to flatten the information within the cellView in order to do the scaling.


    Note that another alternative is to scale the layout - you can do that using the "XScale" UNIX command. Type it with no arguments and you'll get the help - so if you have the original layout and are OK to change it, then you can use XScale to do this.

    Neither of these are on menus.

    Andrew.
