I would like to know what CAD are used by electrical engineers (or electrical engineering students). What does it do and where to get the software? for design entry, HDL is used Basic digital circuits, LSI and CPLD are designed and simulated

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.
This is somewhat subjective, but I'll assume that you want to get a circuit design/idea into a format where you can then produce a printed circuit board from it. I will leave it to someone else to handle simulation and design tools, which are a different matter.
For Schematic Capture and PCB Layout, there are two very popular options that do not have a large monetary barrier to entry (i.e. are cheaper than Altium Designer) with which I have experience.
Anecdocal information about these:
Kicad is less restrictive (i.e. board sizes and layers are not limited) but could have a slightly higher barrier to entry than Eagle. There are a massive number of schematic libraries available on the web Kicad Cloud, Kicad Lib Search, and you can make your own pretty easily Kicad Library Generator.
Eagle has plenty of ready-made libraries of common parts which can be dropped in for quickly designing a circuit. Sparkfun makes a large number of component libraries freely available for Eagle. , As an online alternative for basic schematic capture, there is CircuitLab.
For expanding the functionality of these tools to a team, and integrating some features like quoting, there are also services like CircuitHub.
Since you say you want to use HDL for design entry, I assume that you are intending to program/configure FPGAs or CPLDs. In that case, you should probably first choose an FPGA/CPLD family, then use that manufacturer's design software.
