Do we need .itf file to add capacitance table to mw-library or can I proceed without .itf file? I heard that .itf should be supplied by vendor, but I don't have it. can anyone suggest me a way to work with Astro without .itf file or please share the file for 90nm, 6-metal process. I have capacitance tables with me.
If your Astro .tf file have CapModel or CapTable definition, it means you have tlu model for RC extraction in Astro. You can use it to do placement and routing.
The .itf file is TLU+ model.(use star-RCXT transfer .itf to TLU+ model) The TLU+ model accuracy is more than TLU model.
