When to Use TopMetal2

ChrisDG

Hi,

I am using a new process that contains both TopMetal1 and TopMetal2. Unfortunately documentation is not very useful on when to use either one. Wondered if anyone had any advice on the following:

1. When to use TopMetal2
2. Which is better for Bonding

Thanks.

    Thanks Tawna and Andrew for the replies.
    I was mostly after generic advice/best practices/things_to_avoid for analog designs up to 10GHz if anyone has experience of routing/bonding/grounding in the top metal layers. It is not for anything specific. The foundry only states rules on how to avoid getting DRC errors.

    I realise this is more planning/design related rather than layout tool related so might be outside the scope of this forum (in which case no worries).

    Some requested details below:
    Analog Routing/Grounding
    Layout XL in Cadence Virtuoso IC617
    BiCmos Process

    Thanks.
