Generating .lib file from layout

Hi,

I am trying to generate my own .lib file from the layout I've designed in Virtuoso. I tried to use SignalStorm, but figured out that I do not have license for it. Could anyone please suggest any other tool to do this?

Also, does SignalStorm come along with the standard university package? I remember having it in 2006-07, but after that it was discontinued for some reason. Any info will be helpful.

Thank you.

Regards,

Raj.

Hi Raj,
Depending upon the functionality of your layout, there are several options for creating a dotlib.
1) Encounter LIbrary Chracterization is part of the Encounter Timing System and useful for digital std_cells and I/Os. http://www.cadence.com/rl/Resources/datasheets/library_characterizer_ds.pdf
2) Spectre MDL is a flexible solution for more complex circuits. Results need to be post-processed into dotlib format. http://www.cadence.com/rl/Resources/conference_papers/dtp_cdnlive2006sv_STA_Tseng.pdf
3) Virtuoso ADE-XL has DCM (Design Characterization and Modelling)

I don't have any details on how these are bundled with university packages.
Best regards,

Hi, I am trying to generate .lib for my custom cell using Virtuoso ADE DCM(Design Characterization and Modelling). DCM tool just generates a template based on the user provided values for delay, power and area. Is there any way to generate .lib completely in an automated way ?

Automated is a tall order for a custom cell; however, you should review the Virtuoso Foundation IP Characterization datasheet:
http://www.cadence.com/rl/Resources/datasheets/Virtuoso_Foundation_IP_Characterization.pdf
This technology was acquired from Altos and has replaced DCM in ICADV12.1. It is a more automated approach for library characterization. Without knowing more about the function and process node of your custom cell, it is difficult to know if this would be a better solution than DCM.
