CPS is a kind of networked embedded system.Its trustworthiness and cost are impacted by energy consumption.Because software is the main component of CPS

it is influenced by the energy consumption of CPS.So it has become a major challenge for CPS development to design low-power

high trustworthiness CPS software.Existing analysis and evaluation methods have problems such as the experimental high cost and big price.If the trustworthiness problem of software can be found in the design phase

it can effectively reduce the cost and improve development efficiency.So modeling

analyzing and evaluating the software architecture energy consumption of the CPS software architecture design stage can help find the energy consumption design defects.It can effectively improve the trustworthiness of the CPS software and reduce development costs.Against this

first build the CPS software architecture energy consumption based on the energy consumption time Petri nets;then by analyzing the trustworthiness problems of the CPS software influenced by the energy consumption

propose the evaluation method for CPS software based on the energy consumption model;finally

indicate the effectiveness of the proposed methods through an instance.
