# Description:
# This script is for generating the CSR access test:
# `cv32e40(s|x)/tests/programs/custom/cv32e40x_csr_access_test/`.
#
# It calls a generation script within `riscv-dv`.
# A Yaml config as per `--input_yaml_path` is used as its input.
# See the README in the path mention above for additional usage info.
