I am trying to run a testcase which performs UVM predefined Register Tests. I used
+define+UVM_REG_ADDR_WIDTH=32
+define+UVM_REG_DATA_WIDTH=32
in the run script to overwrite the default address and datawidth for the UVM Predefined sequences(which is 64).
These defines are not being accepted by vlog(and they still remain 64 bits). Has anyone encountered this issue before? Could you please let me know how/where should I specify these defines for the Simulator to accept these defines?
Te Register model I generated is 32 bit wide
create_map(“”, 'h0, 4, UVM_LITTLE_ENDIAN, 1);
Run script:
+incdir+<path_to_src>/verilog_src/uvm-1.1d/src
+define+UVM_REG_ADDR_WIDTH=32
+define+UVM_REG_DATA_WIDTH=32
<path_to_src>/verilog_src/uvm-1.1d/src/uvm_pkg.sv \
Error Message :
UVM_INFO verilog_src/uvm-1.1d/src/reg/uvm_reg_map.svh(1996) @ 40000: reporter [uvm_reg_map] Reading address 'hffffffff80000fe8 via map
As you can see, the error message shows the address being 64 bits wide instead of 32 bits

If I remember correctly, QuestaSim comes with a pre-compiled UVM library (it was called something like mtiUvm), which it automatically loads when it notices you import uvm_pkg into your code. You’ll have to look in the manual how to force it to compile a UVM version with other defines.
In reply to Tudor Timi:
Yes, you are correct. By default it imports a pre-compiled UVM library. I had to re-compile the uvm_pkg for overriding the default defines with the ones I specified and then it works.
In reply to gowthamnirmalraj:
Just make sure that you still get the vendor extension (transaction recording and such) in there (if you care about it, that is). The built-in UVM comes with these goodies, but compiling a pure Accellera version won’t have these.

Hi,
I also encountered the same problem and was wondering how you were able to override the default defines of the pre-compiled UVM library. Could you please tell me how?

Hi gowthamnirmalraj,
While searching the forums for other solutions to this problem, I noticed that you probably replied to my question earlier. However, I cannot see the full content of your reply in this thread. I’m not sure what could be the problem but could you please post your answer again in this thread? I’d appreciate it very much, thanks!

You need to re-compile the UVM base class library “uvm_pkg”(as part of vlog command) and use these defines(+define+UVM_REG_ADDR_WIDTH=32 +define+UVM_REG_DATA_WIDTH=32) along with them for it to take effect.
