3.3 Creating the schematic in Capture

The following steps explain the procedure for developing a schematic in Capture using the part created from the netlist:

  1. Open PAGE1 under the SCHEMATIC1 folder below the .dsn file.

  3. Select all default library files of PSPICE from installation directory and click "Open". (Default Location: “C:\Cadence\SPB_17.2\tools\capture\library\pspice”) Note: This step can be omitted if the default libraries have already been added to Capture.
  4. In the Part search window, type “TPS50601A-SP_AVG” and select the model.

  8. Multiple controllable parameters are present in the model, which can be varied to analyze the model functionality. The default values for these parameters can be found in Section 2. To enable easy access to these parameters, make them visible by double clicking the part. The following window will then appear:
