| Description: | UVM Register Kit for OVM 2.1.2 This package is a near verbatim copy of the register layer portion of the Accellera Universal Verification Methodology (UVM) reference library. Minor additions and modifications were made to enable its use as a standalone package and be compatible with OVM 2.1.2.. Having this register package means that OVM users now have a standard, robust and vendor-independent register solution that will not require rewrites or use-model changes if/when they decide to migrate to UVM. To use the UVM Register package with OVM, you'll need to import the uvm_reg_pkg and include the uvm_reg_macros.svh file: `include "uvm_reg_macros.svh" package my_reg_model; import ovm_pkg::*; import uvm_reg_pkg::*; ... endpackage |

UVM Register Kit for OVM 2.1.2

UVM Register Kit for OVM 2.1.2
Hi,
Has this UVM reg package been compiled and tested with OVM 2.1.1?
No. The standalone uvm_reg_pkg will only work with OVM2.1.2. Along with some important bug fixes over 2.1.1, 2.1.2 includes some restructuring of some base classes and other user-invisible changes to allow integration of the uvm_reg_pkg with OVM code.
In order to use the uvm_reg_pkg with OVM, you'll have to move to OVM2.1.2. As mentioned though, this will not impact the code that you've written.
Good luck,
-Tom

Hi All,
Can anyone point me to the correct way to compile the UVM_REG-1.1 package using OVM-2.1.2 with Cadence Incisive 10.2? I keep getting a compile error complaining that I can't index an associated array with an ovm_object. I suspect there are some specific compile settings that I need to specify, (since UVM-1.1 will compile using the -uvmhome option) but I can't find anything specific in any of the Cadence documentation.
Anthony.
Hi,
Is there a document/example to demonstrate on how to migrate from ovm_register_pkg to uvm_register_pkg?
Thanks.
Tom,
I couldn't find anything in the documentation folder of this register package or UVM register package 2.0. I am looking for base class documentation just like in OVM library. Could you please point me to a tarball which includes the documentation details.
Thanks,
Rajkumar.
Hi Adam,
The version of Incisive is able to compile UVM 1.1 without any issues, as long as I use -uvmhome when invoking irun. However to compile ovm I must use -ovmhome, and only one of these options is allowed on the command line for Incisive. Building using -ovmhome, and paths set correctly to pick up UVM Reg package yield two issues:
1. Missing definitions for the version string defines.
2. (after manually fixing the issue above) I get a syntax error (sorry I can't remember the line at the moment, regarding an associative array with a ovm_object as the index key.
I suspect what is happening, is that something under the hood is set/changed when specifying -uvmhome which allows Incisive to build the full UVM package, but this option isn't being set with -ovmhome. I can't confirm this though.
I've spoken with Cadence AE's about this since my original post and they claim that the UVM REG pacakge modified for OVM is not ported for Incisive, and to use either OVM with OVM_RGM, or straight out UVM. Unfortunately business reasons dictate we cannot move to UVM at this stage, so we are resorting to using OVM_RGM for our register package.
Anthony.
When I use Questa 6.6d to compile the uvm_reg_pkg (I think I need to compile his?), I get compilation errors.
As follows:

Is there anything special that needs to be performed to compile the uvm_Reg_pkg to library?

Questa 6.6d is old, but should and does work for me. You did not show the step for compiling the OVM 2.1.2 package. Try compiling both packages in one vlog command line and see if that make a difference.

Thanks, I tried to combine the compilation, but it made no difference. :(

Hi Pizadood,
I remember Mentor AE telling me that UVM Register package compatibility with Questa is only from 6.6e. So you can try that version.
Hopefully any MGC engineers can comment on this.
Hope it helps you.
Thanks,
Rajkumar.
Questa 6.6d should compile the UVM register package with the OVM. There was just an example that didn't work that needed 6.6e.
This error is very strange because 'ovm_sequence' is not recognized, but it is not the first OVM class to be used by the register package. Can you compile a simple OVM example using 2.1.2 that has an ovm_sequence? Are you able to get Questa 6.6e? BTW, Questa 10.0c comes with both packages pre-compiled.
If you cannot resolve your problems with these suggestions, you should contact Mentor support directly.

I tried Questa 10.0b and the same errors occurred. I agree that it is not a version issue.
Is 10.0c a super set of 6.6d?
You will need to contact Mentor support directly. I have not been able to reproduce your problem with the kit on any version between 6.6d and 10.0c. 10.0c comes with pre-compiled packages, you just need to import the packages.

I encounter a compilation error when compiling uvm_reg_pkg. I am currently using Cadence irun/ncvlog 10.20.030. The error I get is regarding a queue vs. a dynamic array in uvm_reg_map, regarding `UVM_DA_TO_QUEUE(addrs,map_info.addr):
assignment operator type check failed (expecting datatype compatible with 'queue of uvm_reg_addr_t (packed array of bit)' but found 'dynamic array of uvm_reg_addr_t (packed array of bit)' instead)
Has anyone encountered this?
Hi Tom,
Will you be porting the register layer of UVM 1.1a to OVM in the (near) future?
There were quite a number of bug fixes and enhancements in this latest version.
Regards,
Steve
Hi Steve,
We are discussing this now internally. We should be able give you a more definitive date soon.
Adam
I have given another try at this since we updated to a later version of Incisive. I modified the code to do what the typedef is doing and get the same issue. Is it legal to assign a dynamic array to a queue? I don't see why this would be a problem but apparently my compiler thinks so.
addrs = map_info.addr;
