RgbLedMod

Verilog core for managing 3-wire RGB PWM Led (full colors) with blinking support.

Module parameters

The following parameters are configurable:

• Blink period (full cycle on/off) in clock cycles
• LED on value (1 for active high, 0 for active low)
• LED off value (0 for active high, 1 for active low)

Simulation

For simulation purpose, testbench RgbLed_tb is provided.

Simulation is performed with DSim Desktop using VS Code extension and local desktop simulator. Simulation configuration is stored in sim directory.

Steps for simulation:

• Ensure that VSCode extension is installed (metrics-design-automation.dsim-desktop).
• Install local tool (using extension panel).
• Click Manage Licenses button and activate free personal license.
  • NOTE: only one license is allowed.
  • License may be downloaded and manually put to AppData/Local/metrics-ca directory.
• Create sim directory.
• Right click on sim directory and create new DSim project with root directory ..\.
• Right click on Verilog files and add them to project using Configure File command.
• Go to Library configuration panel and compile work library.
• Create the simulation RgbLed_sim with the following options: -top work.RgbLed_tb +acc+b -waves waves.mxd.
• Run simulation.
• Open waves.mxd file for analysis.

Note: See Tutorial for more details on installation, configuration and running.
