Which is better, digital back-end DFT PR electric or PV?

It's all the same, mainly depending on what you like. At present, there is a great demand for verification in the market, and you can choose according to your own preferences. In the long run, your salary will be almost the same.

Digital backend is ok, there will always be recruitment. As for PV, I don't know whether you are talking about physical verification or product verification. The first is a back-end process, mainly because the project is busy at the end, and it is also the first time for newcomers to start learning. The second is EDA company to do tool verification, and the salary is not bad.

The job content of DFT engineer:

① the use of ①EDA tools: DFT technologies such as Scan, Mbist and boundary scan are realized in the design.

(2) Programming: generating test vectors and verifying the test vectors. In fact, there is little programming, which is basically modified from the original template, and the requirements for programming skills are not so high. Basic programming is enough. According to the actual situation, DFT of some companies is also divided into DFT design and DFT verification.

③ Assist the back-end engineer to complete the time sequence convergence of the test mode.

(4) Assisting test engineers in machine testing, debugging faults and improving chip yield. Later ATE testing is also something that DFT engineers often do.
