This paper presents an evaluation of using the hardware/software codesign tool CoWare in education. We present experiences from using CoWare in a course on hardware/software codesign of embedded systems, mainly targeting system on a chip (SoC). CoWare N2C is a system design CAD tool for hardware/software codesign, i.e. the design of hardware and software in an integrated design flow. CoWare supports the incremental design refinement, cost and performance estimation, and interface synthesis. This increases the productivity for designer (student) that can concentrate on system description, hardware/software partitioning etc.
