In reply to chr_sue:
I am also facing the same issue when using the ral model for read the register in my uvm_monitor am getting an error:
Error-[IOUCM] Illegal use of class method
/$PROJ_DIR/hxtop_interrupt_monitor.sv
Though as of nowam using ral model in my TB and all the registers sequences are working fine.
Can you please suggest me wat go wrong here?
