The 7 levels of IP verification

The quality of semiconductor intellectual property (IP) is a major issue for design teams utilizing third-party sources for portions of their SoCs. Quality is even more critical for highly configurable types of IP because customers license it specifically to address the unique requirements of their systems and markets. The on-chip interconnect fabric is perhaps the most common example of highly configurable IP, and its quality is paramount to enable first-pass success for SoC creation.

Thorough verification is critical because the initial cost of configurability pales in comparison to the cost of slowing down a tapeout. Configurability enables customers to innovate in an infinite number of ways; however, its use also makes corner case verification extremely important.
