Summary DioEasy-FIT and GtDio6x-FIT (File Import Toolkit) allows test engineers to easily import STIL, WGL, VCD, EVCD simulation and Teradyne ATP files to DIO or DIO6x files which are used by MTS digital I/O cards. The FIT when coupled with Marvin’s DIOEasy/GTDIO6x vector development / waveform display tools brings a powerful desktop tool set for debugging and developing digital test vectors for all MTS digital instruments without hardware. This article describes how to use the FIT converter tool to convert files.

The Marvin Test Solutions FIT (File Import Toolkit) option is a simulation file translator that engineers can use to easily import STIL, WGL, VCD, EVCD simulation and Teradyne ATP files to Marvin’s compressed digital file format. The FIT converter is available as a separate option for both families of digital I/O products GtDio6x (GX5296, GX5960 Series) and DIOEasy (GX5290 series). Since the features and operation associated with the two options are virtually identical, this article refers to both options as FIT. Both DioEasy and Dio6xEasy coupled with the -FIT option create a comprehensive tool-set for users to translate, view and debug digital test vectors on the user’s desktop or on a Marvin Test Solutions test system. The following article explains the simple process to convert a file.

Licensing the FIT converter

FIT is launched from DioEasy/DioEasy6x by selecting File->File Import from DioEasy/Dio6xEasy, if no license is installed you will be prompted to enter a license string. The license string can be obtained via the MTS support portal (Magic), by creating an incident, providing the FIT Serial number and the Computer ID displayed at the bottom of the License Setup dialog as shown here:

 DioEasy-FIT License Setup

The FIT Window

The following controls are displayed on the FIT window:

Import File
May be entered manually or by pressing the Browse (...) button to browse for the file name to import and convert.

Output DIO File
This file name will be automatically filled in with same name as the Import file with a DIO/DIO6x file extension. The Output file can be any valid file name or file path.

Signals TAB
Once the conversion file name has been entered the Signals Tab of the FIT converter will look similar to the display in Figure 2. The Signal names, UUT Direction and the Bidirectional Control are determined by the selected file. The DIO Channels are assigned automatically. All columns can be easily edited with drop-down choices.

Profile TAB
The Profile Tab provides a simple method to edit signals and also provides a means to change variables or options that will affect the outcome of the conversion. Signals can be copied and pasted from and to the profile tab. This provides a simple method to change the digital channel used, signal name or the UUT Direction. Comments can also be added when followed by a '#'.

As shown below digital channels can be easily re-sequenced, the UUT direction can change or an unused signal can be removed by removing the DIO channel associated with the signal. Once a Profile has been edited it can be saved for use in future conversions. To save a profile, enter the profile name in the Import Profiles drop list then press the Save Profile to File button. See Import Profiles file name selection in Figure 2.

The figure below depicts removed channels, channel re-sequencing, and signal renaming using the file import toolkit.

File Conversion

Marvin Test Solutions' DioEasy-FIT converter will import any STIL, WGL, VCD, EVCD simulation or Teradyne ATP files. The conversion process is the same regardless of the file type. Use the following steps below to import a file.
  • Select the file to import, make sure to select the File type.
  • If necessary enter the target digital file name and path (.dio or .dio6x).
  • Make any necessary changes to the profile or select a saved profile to use for the conversion.
  • Select the board type to use for the target file.
  • Click on Import to begin importing the file.

Once the import process has started, FIT will switch to the Status tab. The Status tab will show the progress of the conversion and will display any errors encountered. At the completion of a successful conversion the status tab will look similar to the display shown in Figure 3. For additional information regarding DioEasy-FIT refer to the DioSoftware or the GtDio6x User Guides.
