module NAME (input, output);
assign y = a & b;
always @(*) begin ... end
always @(posedge clk) begin ... end
<= non-blocking for sequential, = blocking for combinational

Frequently Asked Questions about Verilog
What is Verilog?
Verilog is a hardware description language (HDL) used to model, simulate, and design digital circuits such as CPUs, FPGAs, ASICs, and SoCs. Known for its C-like syntax, simplicity, and dominance in commercial chip design.
What are the primary use cases for Verilog?
ASIC and SoC design. FPGA development. Digital logic design (ALUs, FSMs, DSP blocks). Processor architecture modeling. Hardware simulation & verification
What are the strengths of Verilog?
Easy to learn due to C-like syntax. Fast development and prototyping. Ideal for RTL design. Excellent industry tool support. Core language behind many silicon chips
What are the limitations of Verilog?
Weaker type system than VHDL. Allows sloppy coding if not careful. Race conditions possible with poor coding. Limited structured abstraction vs SystemVerilog. Less strict, easier to write buggy designs
How can I practice Verilog typing speed?
CodeSpeedTest offers 10+ real Verilog code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
