Cell Layout Optimization


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

Optimization rules


Characterization


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

Deliverables



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