Re: Library design
Hi,
The Std Cell Library design flow as follows.
1. Spec from Customer
2. we do some basic analysis(rise time, fall time & pn ratio) to meet the spec.
3. get the approval from the customer
4. circuit design ( schematic, symbol & verilog)
5. Layout Design
6. Physical verification(DRC/LVS)
7. View Validation for Layout, schematic, symbol & verilog to ensure the quality.
8. Lib characterization ( .lib , fastscan, celtic & other view generation)
9. View Validation for the views generated by charact'z team.
10.Sign off & delivery to the customer.
Now coming to your Questions.
1. We extract the parasitics before the Characterization work starts.
2. Follow the above flow.
3. .lib contains all the info.
Hope I have answered your questions.
