UVM_REG backdoor access

Recommended Posts

Hi ,

I am trying to implement register backdoor access with user defined register backdoor by extending uvm_reg_backdoor.

class peri_reg_backdoor extends uvm_reg_backdoor

virtual task write(uvm_reg_item rw);

$root.top.DUT.reg = 8'h41;



when i am compile this code it is showing error

illegal location for ahierarchical name (in a package).

but in examples i am finding that WRITE method is user define and by giving the hierarchy path of register we can directly configure our registers.I want to know what is the overcome for this issue in IUS.

Thanks in advance
