UVM register map and IPXACT

[Khushi]

Hi

I have a set of registers which can be accessed from two different addr maps (uvm_reg_map) and both sees these addresses at different address.

We are trying to generate such uvm registers through IP-Xact. In IP-Xact I can specify registers/register blocks but I am not sure how to specify the fact that one register/register block can be seen at different address via different map/interface. How I can specify the uvm_reg_map in IP-Xact ?

Any clue/example help on this please ?

Thanks

Khushi

Hi Kushi,

You need to describe the complete system in IP-XACT including the masters with their address spaces. For each master, the address map can be computed and a UVM register model can be generated. Different masters would be able to see the same registers at different locations then. As far as I know, UVM does not support the same register at different addresses allowing write to a register via one address and read of that register via another address.

Best regards,

Hi Erwin

Thanks for your comments.

Is it something which is mentioned in section 3.1.6 in https://www.accellera.org/images/downloads/standards/ip-xact/IP-XACT_User_Guide_2018-02-16.pdf

Thank

Hi Kushi,

The user guide does not explain this. Section 12 and 13 and Annex H of the standard explaining addressing. It is not very easy to read though.
