Architecting effective verification components for something as flexible as the Open Core Protocol requires a detailed understanding not only of the corresponding specification, but also the environments and methodology in which the verification component will be used. This article demonstrates how two key aspects of OCP - profiles and transactions - were adopted as fundamental building blocks for the architecture of a verification component targeted at constrained-random validation of OCP components and systems.
The article uses the Verilab OCP uVC as an example. The Verilab OCP uVC is a mixed language OCP compliant verification component that supports a major subset of Open Core Protocol Specification 2.2. The OCP uVC is implemented using SystemVerilog and e verification languages and is compliant with both the Open Verification Methodology (OVM) and e Reuse Methodology (eRM). The verification component can be used in SystemVerilog only applications without the Specman layer (or license), or it can be used in Specman-based verification environments as a regular eVC.
