OVM Field Editor

The OVM Field Editor enables you to inspect and edit OVM field registrations. It allows you to quickly add, remove and edit the registration macros and presents field statistics (total no. of fields, no. of registered fields, no. of warnings/errors).

Triggering

Triggering the OVM Field Editor for a certain class: place the cursor anywhere inside the class definition, right click and select Source > UVM Field Editor from the pop-up menu. If you place the cursor on a field, the OVM Field Editor will show up with the respective field selected.

If there are no previously registered macros, the ovm_*_utils_begin and ovm_*_utils_end macros shall be determined based on the class found at the cursor position. For a class that inherits from ovm_sequence, a pop-up dialog will ask you to select the desired sequencer from the available ones.

Interface

On the left side of the Field Editor Dialog there is a list containing all the fields in the class. You can register/unregister the class by clicking on the checkbox in the Class group. When the class is registered you can register or unregister fields by checking the corresponding checkboxes. When selecting a field you can also find information about the macro used for registration in the OVM Registration Macro group. If it’s not the desired macro you can fix it using the Fix button. On the right side you can see the flag status of the registered fields.
