2.2 Drawing a Basic Schematic

How to get started with a logic design.

The CLB Synthesizer GUI simplifies the process of creating a logic design.

Step 1: Add and configure logic input sources

  • Drag-and-drop an input port from the left side panel onto the canvas

  • Select the input port and configure its source properties in the right-hand panel

  • Repeat as needed

Step 2: Add and configure logic outputs

  • Drag and drop an output port from the left side panel onto the canvas

  • Select the output port and configure its destination properties in the right-hand panel

  • Repeat as needed

Step 3: Add logic content

  • Drag and drop logic gates, flip-flops, multiplexers, LUTs and constants from the palette on the left side panel onto the canvas

  • Connect them up by dragging connections from outputs to inputs, or vice versa

  • Add comments for future understanding

Step 4: Synthesize

  • Click the Synthesize button, and the logic design is converted into a bitstream using a Microchip online service
