UVM_REG : override some addresses of old register model with another register model.

[Attaluri]

Hi ,

   I have a  top register model. in that some address part is defined as memory. ( ex :- 0x0,4,8 ,c registers address then 0x10 memory then 0x20,0x24,0x28 ... registers) 

 

I have another register model , which has all the registers which fit the space defined as memory  in top register model. (ex: 0x10,0x14,0x18,0x1c as registers)

 

could you please suggest me how to map them .

 

Regards,

Pavan.

The question seems a bit vague to me. When accessing 0x10 what are you actually accessing, memory or a register? is there some crazy scheme that when some field in a config register is set, 0x10 maps to one or the other?

Hi Tudor,

   when accessing 0x10 .. plan is to access register.

thier is no crazy scheme here in top register model ,some address part is left for other internal modules.

so these internal modules have thier own register models. so for this internal register models we have to use base address as top model specifies ..

In the top address map, couldn't you just not declare the areas that are mapped to other internal modules? You could then add the other module level map as a submap to the top level one: http://www.vmmcentral.org/uvm_vmm_ik/files3/reg/uvm_reg_map-svh.html#uvm_reg_map.add_submap

Hi Tudor -- Thanks.in generated top address map i commented out those and added other module as submap.
