How to Download and Use TSMC 65nm Standard Cell Library for Your VLSI Design Projects

If you are a VLSI engineer or student who wants to design and simulate integrated circuits using the TSMC 65nm general-purpose CMOS process, you will need the TSMC 65nm standard cell library. A standard cell library is a collection of pre-designed and pre-characterized logic cells that can be used to implement various functions in a circuit. In this article, we will explain what is the TSMC 65nm standard cell library, where to download it, and how to use it for your VLSI design projects.

What Is the TSMC 65nm Standard Cell Library?

The TSMC 65nm standard cell library is a set of files that contains the information and models of the logic cells that are available in the TSMC 65nm general-purpose CMOS process. The TSMC 65nm process is a third-generation semiconductor technology that employs both copper interconnects and low-k dielectrics. It offers better integration and improved chip performance compared to previous generations. The TSMC 65nm standard cell library supports a standard cell gate density twice that of the TSMC 90nm process.

The TSMC 65nm standard cell library consists of more than 800 fully customizable cells that have been optimized for speed, routability, power, and density. The cells include basic logic gates, arithmetic operators, flip-flops, latches, multiplexers, decoders, encoders, etc. The cells also support various features such as power gating, clock gating, scan chain insertion, boundary scan insertion, etc. The cells are compatible with various EDA tools such as Cadence Virtuoso, Synopsys Design Compiler, Mentor Graphics Calibre, etc.
