Application Report SLVA527–June 2012 Importing a SPICE NetList into TINA9-TI John Miller ..................................................................................................................... Analog eLab ABSTRACT This application note describes the procedure for importing an unencrypted SPICE netlist into TINA9-TI (available at www.ti.com/tina-ti), creating a new macromodel based on the netlist, and placing a symbol to instantiate the macromodel in a TINA9-TI circuit schematic. This procedure applies to TINA9-TI only. If you have an earlier version of TINA-TI, see the app note Importing a SPICE Netlist into TINA7-TI (lit number SLVA424). The behavior of the macromodel can depend on the compatibility of the netlist entries with TINA-TI. It is possible that some Spice-based netlists may contain syntax or executable statements that are not compatible with TINA. If the Spice netlist is encrypted and cannot be imported directly into TINA, contact the E2E and Simulation and Models Forum for support (www.e2e.ti.com). The next section provides an example of the step-by-step procedure for importing a Spice netlist to create a TINA-TI macromodel, and then creating an instance of the TINA macromodel on a circuit schematic. The example uses the netlist of an OPA830, a low-power, high-speed op amp with a rail-to-rail output. For additional TINA and/or simulation support, consult the Simulation and Models E2E forum at www.e2e.ti.com . For support on high speed amplifiers like the OPA830 consult the E2E High Speed Amplifier Forum at www.e2e.ti.com.

Procedure www.ti.com 17 18 Netlist viewer window .................................................................................................... 18 Netlist editor display for an encrypted netlist .......................................................................... 19 List of Tables 1 Procedure 1. Importing a SPICE netlist file. The netlist in question must be configured using a SPICE subcircuit statement, and the netlist file must have a .cir, .lib, or .mod extension. If the Spice netlist file has a different extension change the extension to .cir, .lib, or .mod before trying to import it into TINA-TI. To illustrate the procedure, an example is shown below using the netlist for the OPA830: .SUBCKT OPA830 IN+ IN- VCC VEE VOUT Note that this report does not address the details and best practices of generating Spice subcircuits. For more information on this topic, see the References section. 2. Confirming that the SPICE netlist will compile in TINA. Some SPICE netlists may contain statements and/or formatting that is incompatible with TINA. To check for this, open TINA, and select the File/Import/Pspice Netlist (*.CIR) menu tab as shown in Figure 1. Navigate to the desired file and select it using the open directory window. A netlist editor window opens as shown in Figure 2. Select the check-box icon on the upper menu bar as indicated by the black arrow in Figure 2. If the netlist format and syntax are compatible with TINA, then a message that says “Successfully completed” appears in the lower margin of the window as shown in Figure 2. Figure 1.

Procedure 3. Creating the TINA-TI macromodel. www.ti.com Open TINA9-TI and select the Tools/New Macro Wizard menu tab. A window should appear, as shown in Figure 3. Figure 3. New Macro Wizard Start Window Fill in an entry in the Macro Name field, and then click the folder icon to the right of the empty From File field. A pop-up directory window opens. Navigate to the folder containing the Spice netlist file and click on the file icon. For this example, the New Macro Wizard window should appear as shown in Figure 4. 4 Importing a SPICE NetList Into TINA9-TI Copyright © 2012, Texas Instruments Incorporated SLVA527–June 2012 Submit Documentation Feedback Enter the macromodel nameClick the folder icon andnavigate to the directorywith the netlist.

Click the arrow on the right side of the top text field, and a list of the netlist’s subcircuits are displayed. Select the appropriate subcircuit that represents the macromodel and click the Next button.

Assigning a Symbol www.ti.com Figure 5. List of Subcircuits Found in the Macromodel Netlist Highlight the subcircuit that serves as the main call function for the macro. 2 Assigning a Symbol The next step is to pick a symbol for the macromodel. There are two options for creating a macro symbol: 1. Let TINA auto generate a symbol – This option may be best for a unique model, or a model with a large number of I/Os. 2. Pick a suitable symbol from the existing TINA symbol library – This option may be preferred if the model is for a common device, such as a five-pin op amp. In either case, the symbol may be modified later using the TINA9-TI symbol editor that is found in the Windows\TINA9-TI start menu. Highlight the subcircuit that serves as the main description of the model, and click the Next button as shown in Figure 5. 6 Importing a SPICE NetList Into TINA9-TI Copyright © 2012, Texas Instruments Incorporated SLVA527–June 2012 Submit Documentation Feedback Select the downward arrowand a drop-netlist subcircuits will appear.down list of the

www.ti.com 2.1 Auto Generate a Symbol Assigning a Symbol After selecting the main subcircuit in the previous step, the next pop-up window allows the choice of Auto generate shape or Load shape from library as shown in the upper left of Figure 6. Select Auto generate shape and TINA generates a symbol with the model pins located on the left and right sides of the default rectangular shape. Figure 6. Symbol Selection Using the Auto Generate Option Clicking the Next button allows the user to save the completed TINA9-TI macromodel to a local directory. In this example, the default name is OPA830.TSM SLVA527–June 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Importing a SPICE NetList Into TINA9-TI 7

Assigning a Symbol 2.2 Load Shape From Library If this option is selected, then a symbol may be chosen from the internal libraries of TINA symbols. This can be a convenient option for common macros with standard pin-outs such as 5-pin or 6-pin amplifiers. Figure 7, Figure 8, and Figure 9 show the steps after selecting this option. Figure 7 shows the default pop-up window for this example. TINA has identified the macro as a five-pin device and has picked a list of candidate symbols from its internal libraries. The displayed symbol is associated with a five pin comparator. Clicking on the downward arrow on the right side of the symbol shows the other candidates, as shown in Figure 8. www.ti.com Figure 7.
