These are ``mvendorid``, ``marchid`` and ``mimpid``.

The fixed, read-only values for these CSRs are defined in :file:`rtl/cve2_pkg.sv`.

Implementers should carefully consider appropriate values for these registers.

(Allocations are specified in `marchid.md of the riscv-isa-manual repository <https://github.com/riscv/riscv-isa-manual/blob/master/marchid.md>`_.)

If significant changes are made to the micro-architecture a different architecture ID should be used.

The vendor ID and implementation ID (``mvendorid`` and ``mimpid``). The vendor ID (mvendorid) is assigned the value 0x602 and the implementation ID (mimpid) is assigned the value 0x0.
