Cadence DRC check to measure width

Please can you read the Forum Guidelines before posting? If you re-read your question, there are a large number of unknowns here which make it very difficult to answer. The clearer your question, the more likely it is that somebody can give you a clear answer.

Which DRC tool are you talking about? If it's an IC tool, it could be:

1. Diva
2. Dracula
3. Assura
4. PVS
5. Chameleon
6. Calibre (not a Cadence tool)
7. Hercules (not a Cadence tool)
8. several others

Or maybe you're talking about the DRD (Design Rule Driven) checking tool part of Virtuoso Layout Suite XL? Or maybe it's not even an IC tool at all?

Which version are you talking about? 

When you say "even number", what do you mean? Even number of what? Microns, nanometers, grid units, elephants, bananas? (sorry to be cheeky...)

Why do you need to check this? It seems an odd requirement.

Kind Regards,

Andrew.

Hi Andrew,

Sorry for a poorly described question.

I am working on layout design verification using Assura DRC tool version 317.USR2

I wanted to check for the width of a metal which has to be an even number of microns as per design rule. I wanted to know if there is any assura DRC rule which checks for this condition and returns me a failure message when it is not even.

I hope I am precise about my point here.

Please let me know if you could help me.

Thank you,

Deepthi.

That's a very odd rule (especially as an even number of microns would suggest rather large geometries in modern technologies). It sounds as if you need something like offGrid()? (See the Assura Command Reference Manual for more detail)
