Open Laboratory 2020: Cell optimization

Joerg Vollrath

Laboratory Instructions

In this laboratory cells from sclib.jelib and muddlib07.jelib are optimized and characterized.
Pick one cell of muddlib07 for optimization and mail to professor for confirmation.

Cell Layout Optimization

Optimize the cell layout and compare old and new design.
Example: Switch2a, LUT21 as pictured above

Optimization rules


Characterize functionality (truth table), delay times and power consumption with realistic source and load of the old and new cell with and without parasitics.


Explanation what you changed and why.
DRC no errors.
NCC no errors.
Delay times.
Power consumption.

Document your laboratory in a pdf document with a name of <Year>_Cell_ <name>.pdf and send it to joerg.vollrath@hs-kempten.de.
Submission is due 17.7.2020.
