Generating liberty (.lib) files for analog blocks.
Dec 21st, 2010, 11:04am
 
What is the best way to generate liberty (.lib) format timing files for an analog block (e.g. PLL) to be used in a digital top level integration flow?

So far, we have basically used a combination of legacy liberty files and hand-editting new information.

But I was wondering if there are standard tools or flows used for this step?

Thanks.

You can use synopsys libertyNCX tool to generate the lib file.
The tool mainly needs extracted input, model files and hspice simulator access.

There is also a capability in DCM (part of ADE GXL) in Cadence's IC61 release which can help with generation of .lib for mixed signal blocks.

Best Regards,

Andrew.
