Creating Real-Time Test Sequences in TestStand

[bienieck]

I know that I can programmatically create an RT sequence in LabVIEW and Python. This process is briefly described here: NI Documentation and here: niveristand-python Documentation.

I would like to know if the exact same functionality is available in TestStand. I understand that there were some VeriStand custom step types, but they have now been replaced by ASAM XIL step types. Can I use these steps to create system definition (.nivssdf) files? Can I create and run NI VeriStand real-time (RT) sequences from TestStand that work in both the NI VeriStand engine and Stimulus Profile Editor? Additionally, can I run these sequences in both deterministic and non-deterministic modes, as I can in Python?

ASAM XIL Steps cannot create system definition files nor Real-Time Seq. They can be used for deployment only.

To my knowledge, ASAM XIL Target Script Steps only deploy RT Seq in deterministic mode.

The ASAM XIL API is a generic simulator interface for the communication between test tools and test benches. It is not designed to automate the creation of test scripts. Reference: XIL Cross Tests 2016 – Easy Exchange Enabled!

So there is no option to create a TestStand sequence file and automatically convert it to a VeriStand RT sequence, similar to how a Python script defines an RT sequence?

That's correct. I have heard it proposed as a future feature, but you cannot currently run a TestStand RT sequence. They are coming out with VeriStand Steps from TestStand which would allow you to read and write channels, which you could then use in a RT sequence.

Just chiming in, Chase is 100% correct. That functionality is not yet available, but should be releasing in January with the new native VeriStand Steps in TestStand!

Additional question: does it make sense to write RT sequences in Python and run them from TestStand? I'm asking about an alternative because I can't get used to the Stimulus Profile Editor and must read the simplest things several times to understand them.

I just saw a VeriStand 2025 Q! available for download today (27 Jan 2025), is this the new version of VeriStand? If so, are the new TestStand steps for VeriStand also released?

Are the new VeriStand Steps for TestStand supposed to work with the latest 2025 version of TestStand? If not, then what is the roadmap since having to downgrade to 2023 is not a great solution. Also, if not then what purpose does the new LabVIEW+ Suite for HIL offer if you can only use the 2023 Q3/4 versions for TestStand / VeriStand / LabVIEW?
