INTRODUCTION



Introduction




OpenVera is an intuitive easy to learn language that combines the familiarity and strengths of HDLs, C++ and Java, with additional constructs targeted at functional verification making it ideal for developing testbenches, assertions and properties. OpenVera accelerates the creation of a verification environment by providing high-level constructs specifically designed for verification of complex SoCs. Designers create testbenches and assertions using OpenVera and EDA vendors create tools that are automatically interoperable.
