Why is VIP Important?

The backstory on SoC verification

The SoC development process typically requires months of digital simulation effort to verify the functional performance of an SoC before taping out the design. In fact, simulation will usually continue after tapeout and until the time that silicon is received back from the fab. The reason for this extended effort is that functional verification is never finished! SoCs are simply too complex for the logical design to ever be 100% verified. Recognizing that verification is never finished, leading SoC developers make every effort to improve the efficiency of the verification process to complete more verification cycles before taping out a chip.

The benefit of VIP

One of the most time-consuming aspects of SoC verification is creating a testbench that models the SoC's interfaces. Since a typical SoC contains dozens of interfaces such as DDR, USB, and PCI Express, modeling all those interfaces is extremely time-consuming. VIP provides a huge benefit by modeling all those interfaces as components that can be plugged into an SoC testbench and simulated along with the chip.

The use of VIP not only saves man-months of development time, it also frees up valuable talent. SoC interface protocols can be very complex, with specifications that are hundreds of pages long. There are usually very few protocol experts in a company. Using off-the-shelf VIP frees up those valuable resources for other work. Cadence VIP helps you benefit from the experience of others. It incorporates lessons learned from a wide range of projects across many different design applications.
