UVM was created by Accellera based on the OVM (Open Verification Methodology) version 2. Conformity to these standards simplifies reuse by describing insight that is absent fr om the code, making the code more readable and as-. – UVM recommends running a converter script on the source code to replace the ovm_* symbols with uvm_* symbols – This mandates either abandoning the OVM code base of the VIPs or maintaining two repositories – With heavy OVM in use, this is NOT practical as VIPs needs to go into SoCs with OVM base and UVM base running in parallel. Mobiveil is a place where technology and people strike a perfect balance, with employees given space to pursue their careers and their own personal interests. Difference between AHB and AXI?
