Your first project

Create a project

Go to /app. On a first visit, Projects offers three ways to start: Blank project, Describe it, and Import. Choose Blank project and Create: the project opens with top.sv and its test, tb_top.sv. Later, New project at the top of Projects offers the same three.

Run the tests

1. Press Run in the top bar, or ⌘Enter (Ctrl+Enter on Windows and Linux). Every module whose name starts with tb_ is a test.
2. The first run downloads the simulator once and says so in the Tests rail. After that a run starts straight away.
3. Each test reads Passed, Failed at a time, or Stopped, in the Tests rail. The waveform dock opens with every signal under the testbench.

Read the result

1. Click in the waveform to place the cursor. The value of each signal at that time shows beside its name, and beside each line of your code that names it.
2. Hold ⌥ and click a value to see why it has it: the line that set it, the values that mattered, and the clock edge, back to its cause. See Why this value.
3. Press ] and [ to move the cursor to the next or previous edge. ⌘J hides and shows the dock.

Change it and build

1. Edit the design. Diagnostics follow as you type, and the test rows dim to show they ran before the edit. Run again to refresh them.
2. Press Build or ⌘B. The Build view lists the steps as they finish, then the utilization, the maximum clock frequency and the bitstream.
3. With the board plugged in, press Flash. See Flashing for which boards flash from the browser.
