    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

Hi We are migrating test bench from 1.1d to UVM 1.2,

We are facing an issue with uvm_field_array_enum . I have shown the code below

typedef enum bit [63:0] {
A = 0,
B = 2,
C =4,
D='h400000,
E,
F,
..
M ='h400
} myenum_e

class abc ;
myenum_e inst_myenum_e[];
..
..
`uvm_object_utils_begin(abc );
`uvm_field_array_enum (myenum_e,inst_myenum_e,UVM_ALL_ON); // Error on this line - tr_handle is not part of the class
`uvm_object_utils_

endclass

I am getting the Error "tr_handle is not part of the class" on the line as shown above
The code was working fine on UVM 1.1d

Please help us resolve this issue

I can't locate tr_handle in your code snippet first!

In reply to Jack Bryan:

you should extend your class abc from uvm_object or uvm_sequence_item.
that tr_handle may be defined in the base class.

In reply to voraravi:

No tr_handle is not defined anywhere in the testbench

class abc is extended from a class xyz which is extended from uvm_transaction

In reply to Jack Bryan:

tr_handle was part of the vendor specific transaction recording API from OVM/early UVM that was removed in UVM 1.2. It's possible that your mixing macros from different versions of the UVM. This Mentor sponsored public forum is not for discussing tool specific issues. Please read you tool's user manual or contact your tool vendor directly for support.

In reply to dave_59:

Why is this a problem with only uvm_field_array_enum , i am using uvm_field_object and other macros successfully. I observe the same issue with uvm_field_queue_enum

In reply to Jack Bryan:

Sorry, don't use or recommend using any of the `uvm_field_* macros, You have all the source code to debug.
