Compilation issue in ibex bring-up

Hi,

In the process of bringing up the environment for ibex core, Facing issue when tried to bring the spike. In the compile flow, when tried to compile "insn_template.cc" file, the file requires "NAME.h" file which is missing in the repository. could you please help me with this issue.

Below is the path to repository which I am using for spike.
github path: https://github.com/lowRISC/riscv-isa-sim

Error snippet description and file that caused the compilation issue:
git path to the file "insn_template.cc": riscv-isa-sim/riscv at ibex_cosim · lowRISC/riscv-isa-sim (github.com)

Please use the attached image for reference(error_detail_snippet).

Missing the file "NAME.h" in repository. Which is required for the bring up.
Path for the folder: https://github.com/lowRISC/riscv-isa-sim/tree/ibex_cosim/riscv/insns

Start by reproducing the Spike bring-up compilation in the linked lowRISC/riscv-isa-sim ibex_cosim branch and inspect riscv/insns/insn_template.cc together with the contents of riscv/insns. Determine why the required NAME.h file is unavailable in that checkout, then verify that the compilation flow completes without the reported missing-file error.
