Negotiation with lawyer who is sitting behind desk and has clasped hands on document.

Rising design complexity is leading to near exponential increase in verification efforts. The industry has embraced verification reuse by adopting UVM, deploying VIPs and plugging block level env components at sub system or SoC level. According to a verification study conducted by Wilson research in 2012 (commissioned by Mentor) the engineers spend ~60%

Consumerism of electronic products is driving the SoC companies to tape out multiple variants of products every year. Demand for faster, low power, more functionality and interoperability is forcing the industry to come up with standard solutions for different interfaces on the SoC. In past couple of years, tens of new protocols have
