The design and integration of embedded systems in heterogeneous programming environments is still largely done in an ad hoc fashion making the overall development process more complicated, tedious and error-prone. In this work, we propose enhancements to existing design flows that utilize model-based design to verify cross-platform correctness of individual actors. The DSPCAD Integrative Command Line Environment (DICE) is a realization of managing these enhancements. We demonstrate this design flow with two case studies. By using DICE's novel test framework on modules of a triggering system in the Large Hadron Collider, we demonstrate how the cross-platform model-based approach, automatic testbench creation and integration of testing in the design process alleviate the rigors of developing such a complex digital system. The second case study is an exploration study into the required precision for eigenvalue decomposition using the Jacobi algorithm. This case study is a demonstration of the use of dataflow modeling in early stage application exploration and the use of DICE in the overall design flow.
