Create a block diagram

From Fpga4u

Jump to: navigation, search

The block diagram is used to draw logical circuits with predefined components. To create one, draw manually the circuit of the multiplier and follow the instructions:

  1. Select File-->New
  2. Choose Block Diagram/Schematic File
  3. Now you have a workspace on which you can compose your cicuit: double-click on the grid and choose the components you want to add. The logical gates are stored in primitives->logic. Note: using CTRL and the mouse allows you to copy the selected component.

    Here is an example of design for the 2 bits multiplier:


  5. Save and compile your work (use the Start Compilation icon or select Processing->Start Compilation), correct potential errors.

    You may also create your system using VHDL.
Next: Simulation
or go directly to the
Pin assignment
