Verilog provides both behavioral and structural language structures. These structures allow the expression of design objects at high and low levels of abstraction.

  • Designing hardware with Verilog allows the use of software concepts such as:
    • Parallel processing
    • Object-oriented programming
  • Verilog has a syntax similar to C and Pascal.
  • Vivado synthesis supports Verilog as IEEE 1364.
  • Verilog support in Vivado synthesis allows you to describe the global circuit and each block in the most efficient style.
    • Synthesis is performed with the best synthesis flow for each block.
    • Synthesis in this context is the compilation of high-level behavioral and structural Verilog HDL statements into a flattened gate-level netlist. The netlist can be used to custom-program a programmable logic device such as a Virtex device.
    • Different synthesis methods are used for:
  • Arithmetic blocks
  • Interconnect logic
  • Finite State Machine (FSM) components
