Introducing PSpice® for TI

PSpice for TI will help engineers speed time to market and reduce development costs, delivering:

• Full-featured simulation of entire systems.

– Advanced capabilities, including Monte Carlo and

worst-case analysis.

– Synchronized library of >5,700 models and counting. – No design size limitations. – Easy transition to layout and prototype.

• Integrated design resources.

– Quick access to TI product information. – No need to manually upload new TI models.

Why is TI partnering with Cadence?

Short design timelines

Today’s design engineers must

produce accurate designs on tight

deadlines — in many cases,

reducing the prototyping and evaluation phases of their designs.

Growing demand

There is an increased need for simulation software to test new

design concepts, accelerate product

development and demonstrate regulatory compliance.

“Tools that are intuitive and include system-level simulation capabilities can

cut the development time and speed time to market.” – Kevin Anderson, Omdia

Desire for more advanced simulation

Existing simulation tools in the

market lack advanced analysis capabilities, model portability and flexibility, and easy library synchronization.

Software features and limitations FAQ

Q. Does PSpice for TI work offline?

A. Yes, an internet connection is not required to run.

Q. Is there a maximum number of nodes?

A. No, there are no design size limitations. You can also use multi-page schematics and

hierarchical blocks.

Q. Are there any other limits to be aware of?

A. Yes. The tool is designed primarily as a SPICE simulation environment for use with the built-in TI

models. If third-party models are imported, then only three nodes can be probed simultaneously.
