Optimization constraints

14.2 Optimization constraints

Three types of optimizations are possible-area, power and timing. We have optimization constraints related to all these. Synthesis tools assign higher priority to timing constraints over area and power constraints.



Area Constraints:

set_max_area:
set_max_area area_value
# Sets the max area limit for current design.

Example:
set_max_area 20000.0

Power Constraints:
set_max_leakege and set_max_dynamic are the two power constraints that can be provided. (But they are not part of SDC)
