Analog Discovery for HIL (Hardware in the Loop) Test

[mantoll]

I am interested in using Analog Discovery to run CI (Continuous Integration) testing. The DUT is a product with numerous analog inputs, PWM outputs, SPI, UART, GPIO. I want to control Analog Discovery through python to run an automated test suite for HIL (Hardware in the Loop) Test.

Is this a typical use case for the Analog Discovery product?

Also, is manufacturing test a typical use case for the Analog Discovery product?

Hi @mantoll

It could be used but note that on digital side spi, uart and pwm are exclusive, only one function is supported at a time.

Thanks for the response @attila.

Is it possible to measure pulse widths for testing PWM outputs of the DUT through the SDK?

A host computer would be connected to both the Analog Discovery and the DUT. The host run python scripts that would command the DUT to set a PWM output to a certain duty cycle (e.g. 200Hz, 50%).  The Analog Discovery would then, through the python SDK check the signal is what is expected.

This would be one of a suite of tests run in a similar way. Since it is an automated CI test, it needs to be reliable, and run without human intervention after setup.

Is this a typical use case for the Analog Discovery product?

Hi @mantoll

You could perform a digital-in (logic analyzer) capture and process the samples to measure the frequency and duty.
