Verilog Basics Flashcard Set

Front

What is Verilog?

Back

Verilog is a hardware description language (HDL) used to describe digital systems and circuits in code. It was developed in the mid-1980s and is widely used for design and verification of digital and mixed-signal systems.

Front

What are the main types of HDLs?

Back

The main types of HDLs include VHDL, Verilog, SystemC, SystemVerilog, Chisel, MyHDL, and Bluespec.

Front

What is the purpose of a hardware schematic?

Back

A hardware schematic is a diagram that shows how combinational gates should be connected to achieve a specific hardware functionality.

Front

What is the function of a D-flip-flop?

Back

A D-flip-flop captures the value of the input 'd' at the positive edge of the clock and holds it until the next clock edge, unless reset.

Front

What is verification in the context of HDL?

Back

Verification is the process of checking whether the behavior described in Verilog accurately reflects the intended design behavior, often through circuit simulation.

Front

What are the levels of design abstraction in Verilog?

Back

The levels of design abstraction in Verilog include behavioral description, dataflow description, gate-level description, and switch-level description.

Front

What is a testbench in Verilog?

Back

A testbench is a Verilog module that drives the design with different inputs and monitors its outputs for expected behavior.

Front

What is the significance of module declarations in Verilog?

Back

A module declaration in Verilog defines a block of code that implements a certain functionality, including its inputs and outputs.

Front

What are the different modeling styles in Verilog?

Back

The different modeling styles in Verilog include behavioral description, dataflow description, gate-level description, and switch-level description.

Front

How does Verilog help in design abstraction?

Back

Verilog creates a level of abstraction that allows designers to focus on the behavior of the circuit without worrying about the implementation details.
