Re: Parallel testing

My current goal is to set up a measuring station that can run four long-term measurements simultaneously. I want to be able to start and run the measurements as independently of each other as possible.

Is there a function for parallelisation in ATEasy? Otherwise, my idea would be to simply start the created EXE several times.

Ideally, each of the tests should be at a different location. For example:
- Test status 1 has just been started
- Test stand 2 is finished and the test person reloads it
- Test stand 3 is finished and waiting for reset
- Test stand 4 is running

Re: Parallel testing

Yes, ATEasy support parallel testing in one instance. You can have 4 DUT tested at the same time. Each one of them will run on a different thread. Please check the TestExecMultipleUut.prj in the example folder it show sequential and parallel testing. The help file has extensive detail of how to implement that using the TestExec "Look in the Index tab for 'Multiple UUT Testing'. There are also examples in the knowledge base, for example: https://www.marvintest.com/KB/Q200239/ and https://www.marvintest.com/KB/Q200242 and some example for semiconductor testing for multi site.

Re: Parallel testing

Thanks, that looks like what I'm looking for. Is there a way to start each task individually via user input after the tester has prepared the next DUT, or do all 4 tests always have to be started at the same time?

Re: Parallel testing

The Start button starts all 4 of them. If you need to start them individually based on user input, you can use array of critical sections (one for DUT and on Init Program or OnInitTask they can wait (using WaitForSingleObject) until triggered from your user interface or other conditions.
