As for hardware, there are several directions. Simple signals are divided into digital signals and analog signals. Simulation is difficult to do and usually takes a long time to accumulate experience. A single resistor or capacitor is not accurate enough, which may make the signal deviate greatly. With the development of technology, digital analog circuits have appeared, such as the Modem RF module of mobile phones, all of which use mature complete sets of chips.
The other is the digital part, which can be divided into 5 1/ARM single chip microcomputer, DSP and FPGA. Most domestic FPGA engineers are engaged in the front-end verification of IP cores in ic design companies.
An excellent hardware engineer should be able to design products with better cost performance without reference scheme, and make appropriate and feasible tailoring based on the existing scheme.
Therefore, if you want to be an excellent embedded system engineer, you need to grasp the integrity of the system and understand the existing circuits. Secondly, it is the ability to debug the circuit and check the drawings, but the most basic ability is schematic design, PCB diagram and logic design.
This refers to the hardware design engineer. From the above hardware design engineers, we can also divide ECAD engineers, that is, professional PCB drawing engineers and EMC design engineers, to help people solve EMC problems. Hardware engineers are board-level test engineers, that is, hardware engineers with good knowledge of C language. In the process of debugging the circuit board, he can verify the hardware function through his own test program.
