Hardware programming can be an unknown and scary world for many software programmers. The syntax looks like it wasn't seen, the code runs differently, and even compilation and testing are different. So I will take some time to clarify the main difficulties and mysteries of hardware programming so that software developers can better understand what to expect.
Logic Gates Galore:
There are two different types of hardware programming to tell the truth, one that deals with transistor blocks, and another that deals exclusively with logic gates. Here I would like to discuss the future, because it is actually the hardware programming that designers are working on to make complicated chips. VLSI (very large scale integrated circuits) transistor block programming is another topic I am discussing here. However, the logical gates are the next levels above the transistors and are involved in much more complex programming. This is because the VLSI includes the totals of the transistor blocks, rather than automatically programming them, such as Hardware Description Languages.
Hardware Description Language:
This is the code used for automatic programming of higher level logic gate functions. You also need an FPGA (Field Programmable Gate Array) separately from your computer to fully test this code. This is because this FPGA simulates the different functions of the encoded logic gates, basically creating them on the board with all their parameters. This includes timing, which is the basis for all problems that occur during hardware programming. However, the main problems are two things. One is the assembly time because the FPGA is connected from the outside and the code is translated long enough. Ultimately, this will result in longer time for code testing and debugging, which will result in a significant increase in software coding. The second thing is that the code does not run in the same order as the software languages. The HDL code runs in blocks because the real chips work physically. This physical limitation creates programming constraints that disappoint many hardware designers. This is because you cannot fully understand why a certain error may occur and simply because the timing of the circuit is not synchronized.
So I hope I have clarified some hardware programming problems you didn't understand before. I hope that with this information you can better prepare for hardware programming and any expectations.
