Conclusion
This application note highlights some of the benefits of using Cadence® OrCAD® suite and the
capabilities of PSpice for designing and optimization of various designs parameters for a Voltage
Regulator Module. PSpice A/D®, the simulation and analysis tool of OrCAD® products, comes with a
comprehensive built-in device library and simulation models for complex devices such as PWMs. Using
these models, designers can simulate complete closed loop systems and fine-tune transient response of
a system. Tight integration of OrCAD tools facilitate design flow tasks and offer several advantages to
designers. Some of these advantages are:
Reduces design-cycle and time-to-market.
Allows exchange of information in electronic format, thereby improving communication and reducing
errors. Enables engineers to examine tradeoffs while defining and designing electronic circuits,
and teams to simulate these electronic circuits without modifications thus accelerating design
closure and ECOs.
These advantages are amplified when teams or vendors distributed across the globe adopt the same
tools and the same approach.
