Paradigms. For embedded devices, power consumption is
an important aspect. Low power paradigms are dealt with
through special power-saving cell constructs or techniques
such as resource sharing. Great care also has to been taken
to provide a method for testing. A scan chain has to be
inserted, which has an impact on the chip density and also
the timing behaviour. After layout, the achievable clock rate
and the power consumption can be determined. A simulation
on the gate level verifies the final design. What becomes clear
is the great amount of work required when a structural error
is found at this level. Then the complete and time intensive
design process has to be rerun.
