22 Complex SoCs of today consists of a multiple sub-modules working in conjunction.
25 facilitate this, sub-modules in a SoC are grouped into domains, allowing some
31 OPPs.
39 We can represent these as three OPPs as the following {Hz, uV} tuples:
41 - {300000000, 1000000}
42 - {800000000, 1200000}
