Standard Cell Library

SClib

The Atmel Standard Cell Library, SClib, contains a comprehensive set of combinational

logic and storage cells. The SClib library includes cells which belong to the following

categories:

• Buffers and Gates

• Multiplexers

• Flip-flops

• Scan Flip-flops

• Latches

• Adders and Subtractors

Decoding the Cell Name

The table below shows the naming conventions for the cells in the SClib library. Each

cell name begins with either a two-, three-, or four-letter code that defines the type of

cell. This indicates the range of standard cells available.
