Is emulation really a 'chicken rib' for PS developments?
Electronic circuit emulation is conventionally considered a 'chicken rib' in conventional PS developments. I agree, because of following reasons and maybe more:
1.Great difference between emulated result and real circuit.
2.Experience is more important and effective than analysis by emulation.
3.Developing efficiency is a problem.
We are now in a digital era. Is there any new idea with emulation?
If a digital controller becomes a core of a PS, design bottle neck is transferred from all the circuits to codes in the controller. For that loop performance is adjust by software rather than external components' parameters, and almost all protection functions are implemented by codes, and so on, the difficulties of the external circuits around the controller are instead decreased, for their coupling factors are in a certain extent decreased.
Now the bottle neck is to debug the codes. And the codes are rather more complicated than circuits in a certain extent. Code debugging is even a dangerous activity, for the codes' bugs can lead to circuits exploding or flaring, especially for big power circuits. Engineers are long for some God level tools to facilitate the debugging.
Emulated circuits now come on stages. Without PCB designing, and factory manufacturing process, a general purpose emulation board with emulated circuits is enough for debugging code, and without any components damage risks, exploding risks, etc.
Any opinions or ideas about the emulation circuit, usage, etc., are welcome.

ArthurPS: Emulations have all aspects of meaning or implications. Here, I mean a emulated electronic circuit as a tool for debugging codes. It is different from the electronic circuit emulation for designing a PS.

WeiTo build an emulator for debugging the digital controller, I think we need a lot of models to represent the behaviors of the power train topology and the feedback loop. There is a special subject in power electronics called "small signal analysis" or "small signal modeling" to tackle such models. The emulator may be built based on these models. To guarantee the reliability of the software, we still need a lot of test cases to try.

mrpower@Arthur, good educational article about emulation! The world is definitely going digital and AI. Let's enjoy the last meal left on the table :-)
