Create Vias: shapes, drawn areas

JWHoll

Folks,

I am using IC6.1.7 (64b) on Linux, Layout suite L. I'm looking for documentation on the use of the Create Via dialog. Specifically, I cannot locate any information on using the "Shapes(s)" or "Drawn Area" modes of operation. Ideally I could use this tool to produce via arrays to fill a variety of polygons.

In addition, I've tried editing (via the Options button) the "User Min Cut Spacing" to adhere to my PDK's via array spacing values for larger arrays (more than 3 vias), but the tool will always revert to the standard 2-via spacing (which is less than the value required for larger arrays). I can, post-facto, modify these spacing constraints in the object created by the tool, but I'm wondering if there is a way to fix this before placing the via object?

Regards,

JW

    Hi JW

    You can get the info using any of the following 3 methods:

    a. Refer to Virtuoso Layout editor L users guide which is located at: $CDSHOME/doc/vlehelp/vlehelp.pdf

    b. Invoke "$CDSHOME/tools/bin/cdnshelp &" in a terminal window and search for "create via form"

    c. In layout editor, press "o" to display create-via form and press the "Help" button


    Best regards
    Quek
