I am sure you are talking about the .tf files (which are Named as Technology Files). If it's correct - these are basically represent the Technology rules written for the ICC tool. With the help of this - Tool understand different Foundry specific rules , which are part of DRM (Design rule manual). Also it help Tool for routing and other flow of the Design.
Let me know if this much is sufficient - If you need more info - let me know.
thank you for the information given. but i know about .tf files. what i am exactly asking is about technology libraries.. i have read somewhere that these are used for mapping cells using target libraries....
can you please tell me in detail about that technology libraries??
Okay --- Again Are you talking about the .lef file ? Tech lef files the story is same.
I would say that it will be good if you give more detail about when you are saying "Technology Libraries". It's sometime very confusing -
Please give us any file name so that we can understadn more clearly - what exactly you need to ask.
"The target_library specifies the name of the technology library that corresponds to the library whose cells the designers want DC to infer and finally map to."
actually these link and target libraries are a bit confusing...
i have one more doubt..
considering synopsys tool, what makes the difference between link library and target library when they are sourced in both dc and icc?? and why to source them in both the design compiler and ic compiler.
