With the assistance of a complex singlet, and a effective operator involving CP violations, the dark matter relic abundance and baryon asymmetry of the universe (BAU) are accommodated simultaneously. The mechanism Electroweak baryogenesis (EWBG) is studied systematically: from the necessary condition strong first order electroweak phase transition (SFOEWPT) to BAU generation. The SFOEWPT takes one step or two steps due to the dynamics of the energy gap of the Electroweak vacuum and the vacuum of the complex singlet with the temperature cooling down. Two steps case always give rise to higher magnitude of BAU.
