Prerequisites

Pin Map

Select ECU Toolkit » Pin Map File or click the Edit Pin Map File button on the ECU Software Toolkit toolbar to open the Getting Started with ECU Toolkit pin map file in the Pin Map Editor. The pin map file defines the following information:

• Four NI Switch Executive virtual devices named J5_MATRIX_VD, J7_MATRIX_VD, J12-FIU-1-VD, and J12-FIU-2-VD.
  • J5_MATRIX_VD is created with a Matrix Switch named J5_MATRIX, which is used to build the connections between the instrument channels and DUT pins on Site 0.
  • J7_MATRIX_VD is created with a Matrix Switch named J7_MATRIX, which is used to build the connections between the instrument channels and DUT pins on Site 1.
  • J12-FIU-1-VD is created with an SLSC FIU device named J12-FIU-1, which is used to build the connection between the J24_PPS_1 channel and the DUT pin LOAD on Site 0.
  • J12-FIU-2-VD is created with an SLSC FIU device named J12-FIU-2, which is used to build the connection between the J24_PPS_2 channel and the DUT pin LOAD on Site 1.
• Two NI-DCPower instruments named J18_SMU and J20_SMU.
  Note These instruments belong to two different groups, so they can be controlled by different NI-DCPower sessions. Each site has an independent NI-DCPower instrument.
  • J18_SMU can be connected to the DUT pins on Site 0 using J5_MATRIX_VD.
  • J20_SMU can be connected to the DUT pins on Site 1 using J7_MATRIX_VD.
• One NI-DMM instrument named J5_DMM which is shared across two sites.
  • J5_DMM can be connected to the DUT pins on Site 0 through J5_MATRIX_VD, and connected to the DUT pins on Site 1 through J7_MATRIX_VD.
• Two NI-SCOPE instruments named J22_SCOPE_1 and J22_SCOPE_2.
  Note These instruments belong to two different groups, so they can be controlled by different NI-SCOPE sessions. Each site has an independent NI-SCOPE instrument.
  • J22_SCOPE_1 can be connected to the DUT pins on Site 0 using J5_MATRIX_VD.
  • J22_SCOPE_2 can be connected to the DUT pins on Site 1 using J7_MATRIX_VD.
• Four NI-RMX power supplies named J24_PPS_1, J24_PPS_2, J24_PPS_3, and J24_PPS_4.
  • J24_PPS_3 is connected directly to the DUT pin POWER on Site 0.
  • J24_PPS_4 is connected directly to the DUT pin POWER on Site 1.
• Eleven DUT pins named POWER, A_SMU, A_DMM, B, C, D, E_SMU, E_SCOPE, F_SMU, F_SCOPE, and LOAD are defined in the pin map.
  • The defined DUT pins A_SMU and A_DMM are virtual pins that refer to a single physical DUT pin A. They are used to build connections between the physical DUT pin A and NI-DCPower or NI-DMM instruments using Switch Executive devices.
  • The defined DUT pins E_SMU and E_SCOPE are virtual pins that refer to a single physical DUT pin E. They are used to build connections between the physical DUT pin E and NI-DCPower or NI-SCOPE instruments using Switch Executive devices.
  • The defined DUT pins F_SMU and F_SCOPE are virtual pins that refer to a single physical DUT pin F. They are used to build connections between the physical DUT pin F and NI-DCPower or NI-SCOPE instruments using Switch Executive devices.
• Two pin groups named AnalogPins and DigitalPins.
• Two sites on the tester.
• A series of connections for each site. Each connection specifies a DUT pin, a site number, an instrument, and an instrument channel. There are two types of connections in this pin map file:

  Connection—A connection between a DUT pin and an instrument channel on one or more sites.

  Switch Executive Connection—A switched connection between a DUT pin and an instrument channel for one site through a Switch Executive virtual device. You must specify a Switch Executive virtual device for Switch Executive Connections.

Test Program Configurations

MainSequence, ProcessSetup, and ProcessCleanup Sequences

External Limits File

Use a text editor or spreadsheet software to open and review the test limits file for the Production configuration of this test program, located at <TestStand Public>\Examples\NI_ECUToolkit\Getting Started with ECU Toolkit\ProductionLimits.txt. The test limits file is loaded at run time based on the current test configuration, and specifies the values to use to evaluate whether a measurement passes or fails. The test program stores the limits loaded from the test limits file with the results.

Switch Executive Virtual Device Configuration Files

Use a text editor or spreadsheet software to open and review the virtual device configuration files located in the <TestStand Public>\Examples\NI_ECUToolkit\Getting Started with ECU Toolkit\Switch Executive Virtual Device Configuration folder. There are four files in this folder, which correspond to the NI Switch Executive virtual devices J5_MATRIX_VD, J7_MATRIX_VD, J12-FIU-1-VD, and J12-FIU-2-VD. These files contain the defined alias for the Channel IVI name, as well as route and route group information. The route and route group names used in this test program follow the recommended naming scheme.
