How to view the order of layer from bottom up or top-down of a component in layout?

BaaB

In Virtuoso Layout, is there a way to check the order of layers for a component such as NMOS from bottom up?

With bottom up, I mean the order something like this (for nmos):

1. p substrate

2. np

3. FOX

4. Poly

(this is not totally right but just take it as an example)

Thank you.

    I don't really understand your question - this is not something the user has to enter. The numbers in the functions section of the tech file (as talked about in your other post) are supposed to indicate the order of the layers, but for the most part it doesn't matter to the tools - that's a manufacturing step. There are a few things here and there which do need the sequence of layers - and they would get it from the numbered sequence in the functions section.

    Regards,

    Yeah, thank you.

    I've just checked the number in layerRules section and you are right. The order of layer listed there is already in the order from bottom up.
