Bringing the Idea of MARS to Life An application report on HW/SW-codesign for a medical product

The development process for the electronic part of a microprocessor driven product can be divded into two separate tasks- the hardware development and the software develop-ment. Unfortunately the software team must usually wait for the first draw of the hardware to start with its task. To speedup such a process it is necessary to parallize both development streams. One possible way to do this is the use of a simulation model of the later hard-ware. We intensively use the SMARTMODEL components for a reduction of the spends on the realisation of this model. Particularly for standard components like microprocessors or memory the utilization of SMARTMODELs will drastically reduce the effort in describing the circuit and improve the correctness of the developed simulation model in the same way. To optimize the effort on both tasks we have developed a hardware/software codesign flow with which the two streams can be coordinated
