In the lecture we will have a look at (some of) the following documents:
Standard Cell Student Project: »Kogge Stone Adder
Cell libraries in the public domain:
»0.5 Micron Cell Library
Another »90nm Cell Library
Some others: »VLSI TECH
Things to note: there's a good variety of basic gates, including quite a few multi-level gates, such as AND-OR gate. There's also I/O pads, flip-flops and special function cells. Many gates are available with various output powers.
For each gate there are comprehensive figures that enable one to predict its delay and energy use, taking into account its track loading, how many other gates it is feeding and the current supply voltage.
