Advanced Topic 49 of 51 Computer Architecture & Logic

Hardware Description Languages

Languages like Verilog describing digital circuits.

How it works

Verilog and VHDL describe circuits as modules with concurrent assignments and clocked processes, which are synthesized into gates and simulated for verification.

Where it is used

Designing CPUs, FPGAs and ASICs.

Common pitfall

Thinking sequentially; HDL describes hardware that all runs at once.

Where it fits in the course

Hardware Description Languages is topic 49 of 51 in Computer Architecture & Logic, rated Advanced. It follows FPGA. The next topic is ARM and RISC-V.
