    Study Notes

    HDL Design Flow

    • Synthesis follows RTL design in the HDL flow.
    • Verification ensures the design meets its specifications by simulating and testing the design.
    • Simulation is used to test and debug HDL designs, with common tools including ModelSim, Verilog, and VCS.
    • Place and Route is part of the Physical Design stage which comes after synthesis.
    • Synthesis converts RTL code into a netlist, which is a description of the circuit's logical connections.
    • Optimization techniques like pipelining improve performance by breaking down complex operations into smaller, parallel stages.

    HDL Code Examples

    • Verilog NOT gate (inverter):
    module not_gate (input in, output out);
      assign out = ~in; 
    endmodule
    

    HDL Verification

    • Verification aims to ensure the designed hardware functions correctly by simulating and testing its behavior against expected results.

    HDL Benefits

    • HDL simplifies design by using a higher-level description of logic circuits, instead of directly specifying transistors, making it easier to design and modify complex digital systems.
    • Verilog and VHDL are the most common Hardware Description Languages used in digital design.
