The Quick Start Guide aims to help you get up and running quickly. It also serves as a high-level bird's-eye view of the entire process from getting your Gemini Stimdeck configured to running test programs.

Gemini Stimdeck Setup
  1. Unbox the Gemini Stimdeck and connect the four standoffs
  2. Carefully connect your mezzanine dut board to the Gemini Stimdeck
  3. Place the Gemini Stimdeck on a benchtop, making sure it won't slide off
  4. Plug the Ethernet cable into the network port
  5. Insert a FAT32 formatted and partitioned SD Card with the gemini.conf file on it
  6. Finally, plug the power connector into the DC barrel jack

The Gemini Stimdeck will begin its boot sequence. You should see a green led flashing as it's booting. Once it finishes, if it successfully completed the boot sequence, the flashing green led will turn solid. If the boot sequence failed, you should see the red led next to it turn on.

The most common reason why the boot sequence fails, is if the Tester fails to successfully obtain an IP address. Please work with your Network Administrator to correctly configure your Tester.

Test Patterns and Programs
  1. Obtain your DUT Board PCB's hardware netlist
  2. Translate your netlist into a DUT Board Profile
  3. Write test patterns to test your DUT using the Dots language
  4. Compile your Dots files using Leda the compiler
  5. Create a test program Prgm file
Accessing the Web App

By default, the Gemini Stimdeck will get assigned an IP address automatically using DHCP. Otherwise, the tester can be configured with a static IP address. Please talk to your Network Administrator to get the IP address of the Tester on your local area network.

  1. Obtain the Gemini Stimdeck IP address from the Network Administrator
  2. Open a web browser like Firefox, Chrome or Edge
  3. Navigate to http://<ip_address>
Running Test Programs

The Gemini Stimdeck needs a way to access your test programs and compiled test patterns, because it does not have an on-board hard drive to store your files. Please talk to your System Administrator to set up an NFS drive on your local area network.

  1. Using the Web App, add an NFS mount to the Gemini Stimdeck
  2. Navigate to the Test Programs tab from the menu
  3. Click "New Test Program"
  4. Fill out the form
  5. Finish by clicking "Queue Test Program"

The test program will be queued to run. Once it starts executing test patterns, its status will change to running. You can navigate to the test program overview page and see the status of the test patterns as they run. Test patterns can either pass or fail. If they fail, you can see the failing test cycle number that corresponds to the vector in your Dots file.


You have successfully configured your Gemini Stimdeck and ran your first test program!
