Title: Formal Sign-off methodology for IP blocks
Language: Mandarin
Abstract — Coverage driven simulation-based verification is used as the primary verification methodology for modern SoC designs. It requires a lot of effort to build the test environments, from IP blocks, to sub-systems and finally the SoC system. Implementing comprehensive coverage metrics is critical, but also error-prone and time-consuming. Moreover, functional coverage metrics are often incomplete when design features change dynamically, resulting in coverage holes. We augment the UVM simulation-based sign-off process with formal verification to deliver high quality devices and we apply formal techniques where it improves effectiveness and productivity. We use several formal methods, and block level formal sign-off in the SoC verification process. This paper discusses the formal sign-off methodology for IP blocks in our SoC designs.
