Sometimes we miss the forest for the trees, and I’m as guilty as anyone else. When we think testbenches, we rightly turn to UVM because that’s the agreed standard, and everyone has been investing their energy in learning UVM. UVM is fine, so why do we need to talk about anything different? That’s the forest and trees thing. We don’t need to change the way we define testbenches – the behavior and (largely) the top-level structure. But maybe there’s a better way to assemble that top level through a more structured assembly method than through hand-coding or ad-hoc scripting. Still built on UVM at leveraging the standardization benefits of IP-XACT for assembly around VIPs.
