This diagram emphasizes the role of VHDL in the RASSP program. VHDL can be used for system definition, functional design, hardware-software partitioning, hardware design and hardware-software integration and test. In RASSP, virtual prototyping uses VHDL as the binding language of choice for all design paradigms.
The most common usage of VHDL prior to RASSP was in the area of hardware design. The RASSP program has extended VHDL's use to include executable requirements, performance modeling, system level design as well as system integration and test.
