The objective of this paper is to describe and demonstrate a methodology and tools to enable System-Level designs to be synthesized, assessed and selected. To accomplish this logically the approach attempts to be consistent with Decision Theory as associated with Value-Driven Design; while to ease adoption it makes use of the standardized modeling languages of Object Process Methodology (OPM) and Modelica as part of the broad area known as 1D-CAE. The approach involves defining unambiguously what value the system aims to deliver in a functional description and then decompose this single function into multiple sub-functions. The sub-functions are used to define system architectures which deliver the functionality which subsequently onto which actual designs are composed. These actual designs are then assessed against the primary value defined at the start of the process. The approach is demonstrated on an automatous solar powered boat where it is shown the primary value of Racing in SolarBoat Race Event can be used to drive the synthesis of designs and assess them.
