MultiSIM BLUE equips design engineers with the tools they need to build circuit schematics, perform SPICE circuit simulation, rapidly layout PCBs, and order components from in an integrated environment.

In order to provide the latest electronic components in their catalog, Mouser Electronics will be providing regular updates of the component database of MultiSIM BLUE. While using MultiSIM BLUE, users can check if any database updates with new parts are available, download, and apply these updates to their design environment.

The MultiSIM BLUE launcher and BOM tool is capable of automating the process of updating the Mouser Database and loading it into the software environment. The Mouser database could also be used in any version of Multisim, such as the Student, Education, or Professional Editions. In some cases users may need to manually download the database update and save it to a specific location instead of automatically doing so through MultiSIM BLUE.

Reasons to Apply a Manual Update

Users around the world may need to rely on the manual update process in cases such as:

  • Having an unreliable connection or no regular access to the internet
  • Having internet firewall settings that block MultiSIM BLUE

Steps for Manually Updating a MultiSIM BLUE Database

  1. Download the latest update that you would like to apply (list below)
  2. Make sure that both Multisim and the MultiSIM BLUE Launch Tool are closed
  3. Save the Mouser database file (Mouser Database.mfr) to the following location:
    For Multisim Component Evaluator Mouser Edition:
    C:\Users\Public\Documents\National Instruments\Multisim Component Evaluator 13.0\Manufacturer Databases
    For all other Multisim editions:
    C:\Users\Public\Documents\National Instruments\Circuit Design Suite 13.0\Manufacturer Databases
  4. Save the “updates.txt” file to the following location:
    C:\Users\YourUserName\AppData\Local\Mouser Updates
    For Windows XP users:
