How to create templates for vdd/vss nets in Virtuoso

akbhide

I am working on the layout of a full custom digital design in Virtuoso. I have now fixed my pitch for the vdd and vss nets. Can anyone tell me as to how i can create templates of some sort of a ruler/guide for these nets which can help me to see where my vdd vss nets/tracks would lie in the layout .It will make my life easier so that i will know how exactly i want to shield or route my critical nets and also ensure that i do not route anything else over the tracks meant for vdd/vss. This will help to reduce the risk of shorts as well.

 Any help, pointers would be really helpful.

  • In IC5141, you can use (in Layout XL) Design->Save to Template from an existing view, and save info about the I/O pin locations or constraints.

    This template file can be referenced at the bottom of the Design->Generate from Source form. Also, if you use Place->Pin Placement, you can choose to place pins as in a Template File. You can create (for example) the pins how you want (including using the Hrail/Vrail options) from this same Pin Placement form.

    IC61X has a similar (but with further enhancements) pin placement UI.

    Regards,

    Andrew.
