The “syntax” of FPGA (Field Programmable Gate Array) essentially refers to the rules for using hardware description languages (HDL, such as Verilog and VHDL) and associated design tools to describe hardware circuit logic. Compared to software programming languages (like Python and C++), the core difficulty of FPGA syntax arises from the conflict between its “hardware … Read more
