[BUG] cve2_riscv_compliance simulator fails to load any ELF/vmem

[karabambus]

Bug Description

Running Vcve2_riscv_compliance with any ELF or vmem file immediately fails:

ERROR: No memory found at TOP.cve2_riscv_compliance.u_ram.u_ram.gen_generic.u_impl_generic' (the scope associated with region ram', used by a segment that starts at LMA 0x0).

The scope path hardcoded in dv/riscv_compliance/cve2_riscv_compliance.cc (line 17) is:

  MemArea ram(
      "TOP.cve2_riscv_compliance.u_ram.u_ram.gen_generic.u_impl_generic",
      64 * 1024 / 4, 4);

The path segment gen_generic.u_impl_generic does not exist in the current prim_ram_1p.sv.

The stale path originates from commit 8b42024 ("Use vendored-in primitives from OpenTitan"), which updated the scope to use the then-current primgen wrapper hierarchy (prim_ram_1p → gen_generic.u_impl_generic). A subsequent update to fusesoc_libraries changed prim_ram_1p.sv to a flat implementation, but the .cc file was not updated accordingly.

Fix

In dv/riscv_compliance/cve2_riscv_compliance.cc, change:

MemArea ram(
    "TOP.cve2_riscv_compliance.u_ram.u_ram.gen_generic.u_impl_generic",
    64 * 1024 / 4, 4);

to:

MemArea ram(
   "TOP.cve2_riscv_compliance.u_ram.u_ram",
    64 * 1024 / 4, 4);

Steps to reproduce

1. Build Vcve2_riscv_compliance per dv/riscv_compliance/README.md
2. Run with any ELF: ./Vcve2_riscv_compliance -E .elf
3. Observe the error above
