cv32e40x-dv is the core-specific design-verification environment for CV32E40X. It separates software-test compilation, UVM infrastructure, simulation, top-level testbench code, test cases, and formal-verification runs, giving engineers a direct map from an RTL change to the relevant verification area. Use it together with the CV32E40X RTL repository and shared core-v-verif components when validating the core or its custom-extension interface.

CV32E40X is a compact four-stage, in-order 32-bit RISC-V core for compute-oriented embedded systems. Its defining feature is CORE-V-XIF, which lets designers implement custom instructions in an external coprocessor without embedding that logic directly in the CPU pipeline. It is most relevant to engineers and researchers exploring domain-specific acceleration, but adopters should note that the core is considered mature while not currently progressing toward its TRL-5 target.
core-v-verif is shared functional-verification infrastructure for CORE-V processors. It combines reusable UVM components, simulation Makefiles, verification libraries, utilities, vendor dependencies, and DV plans, with dedicated directories for CV32E40P, CV32E40X, and CV32E40S. Verification engineers can start with the common methodology and then select a core-specific flow. For CVA6, use the verif directory in the CVA6 repository: the current core-v-verif tree does not contain a CVA6-specific directory, although CVA6-related environments can reuse its shared components.
