41.11 UVM Library Compilation Troubleshooting
This application note covers several types of configuration issues you might encounter when working with the UVM library:
1) Error messages like:
Error: SYSTEM_VERILOG_2012: Cannot open `include file "uvm_macros.svh"
Error: SYSTEM_VERILOG_2012: Undefined macro name: `uvm_object_utils_begin
Error: EXTEND_CLASS: Extending non existing class 'uvm_agent
These errors indicate that the UVM library was not compiled or that the
uvm_pkg has not been imported properly.
To check whether the UVM library was compiled:
If the library is not compiled add the
'-uvm' argument to your build file or one of the
compatibility modes specific flags.
Also make sure the uvm package is imported in the scope where the errors are reported.
2) Error messages like:
Error: METHOD_CALL_ARGUMENTS: Expecting maximum '0' arguments when calling 'new', found '1'
Error: ILLEGAL_ASSIGNMENT: Illegal assignment of 'literal_string' to argument 'stream' of type 'uvm_tr_stream'
Error: UNDECLARED_IDENTIFIER: Identifier 'factory' is not declared
These errors can happen when there is a mismatch between the UVM version that is compiled by DVT and the one used by the project.
For example there are two scenarios for the
2a) The first one is the mismatch scenario.
The error is thrown for classes that do not define a constructor with a string argument for the name.
Although this is not an issue with older UVM versions such as
uvm-1.1d, it is an issue for
From the pictures above it can be observed that by default the
uvm-1.2 version enforces a constructor with a string argument.
To quickly check which version was compiled by DVT, disable the
Content Filters using the toolbar button , open the
Macros View and search for
To compile a different UVM version see
SystemVerilog OVM or UVM Library Compilation.
2b) The second scenario is where the simulator CLI gets passed
+define+UVM_OBJECT_DO_NOT_NEED_CONSTRUCTOR but the directive is missing from
3) Error messages like:
This typically happens when compiling the
uvm-1.1c version and not specifiying a compatibility mode. The solution is to specify a
