RTL Design Explained

Describing hardware in Verilog and SystemVerilog.

Quick Answer

What is RTL Design Explained?

RTL (Register Transfer Level) design describes hardware behaviour in terms of data flowing between registers. It is written in Verilog or SystemVerilog, simulated to check correctness, then synthesised into a gate-level netlist.

Quick primer

RTL is hardware description, not programming. You are describing what the circuit should do every clock cycle — which registers latch which combinations of signals. Synthesis then converts your description into a gate-level netlist. The RTL you write influences area, timing and power more than most beginners realise, which is why senior designers care intensely about coding style.
