Subject: Virtual Bench Pro v4: Merging single-device configurations into a multi-device project

Hello MPS Support Team,

I am running into a workflow limitation with Virtual Bench Pro v4 and would appreciate your guidance on how to combine project files.

Hardware Setup

  • I am bringing up a custom board featuring three I2C/PMBus modules: two MPM54524 and one MPM3695-20.

  • I2C communication is functioning perfectly. Virtual Bench Pro successfully scans the bus and identifies all three devices at their unique addresses.

The Issue

  • I have previously configured each regulator individually using separate evaluation boards and saved their configurations as individual .spec (XML) project files.

  • When I scan my new custom board, the software creates a new multi-device project. However, I cannot find a way to import my existing single-device .spec configurations into the individual chips within this new device tree.

  • Opening an old single-device project clears the multi-device view, and creating a new multi-device project forces me to enter all parameters from scratch.

Questions

  • Is there a built-in feature to import or load a saved .spec configuration into a specific IC within an active multi-device project?

  • If the GUI does not support this natively, is there a recommended workaround or documentation for merging the XML .spec files manually without corrupting the project structure?

Thank you for your time and support.

Best regards,

Stefan

Hi Stefan,

Inside of Virtual Bench Pro 4.0 menu bar there is a user guide: Help > User Manual.

Sections 3.4 and 3.5 of this user manual cover how to save a device configuration and import a device configuration. Typically these configurations are stored as .txt files.

Please let me know if following these procedures works for you.

Thank you, Will

That works for one device but not for three devices in a I2C chain. There is the setup of my PCB. For each of the MPMs I have a separate .spec file (which I can export to a ATE file). Now I just want to integrate them all into a single Board Project file.

However, as soon as I select one MPM and select ‘import from ATE’ the other two devices disappear from the project.
