In reply to chr_sue:
has_hdl_path is 1. But write is not happening.
This says you have defined a hdl_path, but it doesn’t say it’s correct.
backdoor access has specified commands for Read and write. I’d recommend to use this to be sure you are working backdoor.
The backdoor write is poke and the backdoor read is peek.
You can also use uvm_hdl_check_path to check if the hdl_path is existing.
