PCB Design Blogs

When time and quality are at a premium and you are in a hurry to meet a tight schedule, access to 5000 tried and tested TI-PSpice models across 100 categories, not to mention the 4000 test circuits, definitely gives you the edge you needed. You can quickly identify and correct any issues in the design by running a simulation using the most appropriate model from the Texas Instruments library. What do you need to do, you ask, to make this possible? Well, not much actually. Install HotFix 014 or later of Release 17.4-2019 along with S006 or later of PSpice^® for TI and you are ready to go. Let’s then discuss the details and the steps.

Available Categories and Models

For ease of access, the Texas Instruments library is organized into a dozen or more super categories, if I may say so, that includes further categories. If you are used to researching the parts on TI.com before or while you are designing, you might be happy to notice the similarities in the taxonomy that gives you a consistent approach to searching and using parts you need.

For example, Amplifiers itself has eight categories, the categories Current sense amplifiers, Operational amplifiers (op amps), and Special function amplifiers having further subcategories as is appropriate looking at the range of models available under these categories. As you can see, even at the top level, Comparators has more than three scores of models.

Similarly, if you browse down to the Operational amplifiers category, there are more than 281 General-purpose op amps at your disposal.

You must already be eager to look at the other categories and models of your interest and more than anything use them in your designs. So, let’s then move on to the steps to use these models.

Accessing and Using the TI Models

Accessing the TI library and its models is quite intuitive from the PSpice Part Search pane.

To see a list of the models and place them in your design, do the following step:

1. Choose Place – PSpice Component – Search to open the PSpice Part Search pane.

2. Choose the library or a category or subcategory to see a list of the models in the selection.

For example, choosing Difference amplifiers under Amplifiers lists all the 14 models in that category.

3. Right-click the part of interest and choose one of the many options available for various tasks, such as to place or view the symbol, view parameters, open the product page, open TI E2E page for any help, or open a model test circuit.

You can also double-click a part to place it in the design.

Choosing an option from the Open Model Test Circuit menu will open a test model circuit that is ready to simulate.

Now that you have a circuit that is ready to simulate, simply click Run () to see the simulation results. You can view the results in just about a few seconds compared to what will take several minutes if you search a part and then create a circuit before configuring the simulation profile, and then running a simulation in the normal process.

While at it, you can also explore the other options in the pop-up menu. You will be using Place Symbol and View Symbol quite often, but I will also encourage you to explore the Open Product Page and Open TI E2E Page options. With these options, you can access very useful and recent information on the part in one click. Product Page gives you instant access to datasheets, product information, and support. The TI E2E page has relevant discussions on real user queries and solutions.

Conclusion

When every second counts and quality is not negotiable, having a large number of useful PSpice models that are reliable and that can be used immediately and quickly helps enhance design quality and productivity. You should be able to use the TI library and its models in your PSpice simulations immediately if you are using the latest update of the software.
