(Bug?) uvm_reg_map get_size method ignores the n_bytes attribute

[rtdk]

In the uvm_reg_map get_size method, the output comes from last known register's address. At the end of the method, the return value is:
 

 return max_addr + 1;

https://github.com/accellera-official/uvm-core/blob/b5f8562d8bee8ea11b06fc2692ed2ba0b5b7eeb7/src/reg/uvm_reg_map.svh#L1324C4-L1324C23

Instead, the function should return:
 

return max_addr + n_bytes;

Which would return the right value.
I've created a playground to demonstrate it:
https://www.edaplayground.com/x/mhic

I have 3 64b registers in the map. I expect the get_size method to return 'd24, because the total map occupies 24 bytes. Instead it returns 'd1

 

UVM_INFO testbench.sv(69) @ 0: uvm_test_top [uvm_test_top] Size of reg map is 17

 

I wasn't sure how to file a bug on UVM, so here I am.
