The UVM Field Editor enables you to inspect and edit UVM 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 the UVM Field Editor for a certain class: place the cursor anywhere inside the class definition, right click and select 'UVM Field Editor' from the pop-up menu. If you place the cursor on a field, the UVM Field Editor will show up with the respective field selected.
If there are no previously registered macros, the `uvm_*_utils_begin and `uvm_*_utils_end macros shall be determined based on the class found at the cursor position. For a class that inherits from uvm_sequence, a pop-up dialog will ask you to select the desired sequencer from the available ones.
The user interface is composed of 5 panels (Summary, Fields, UVM Registration Macro, Field operations, Print radix) and a message area (#12). On the left side you can find information about the registered fields (#1), scroll through a list containing all the fields in the class (#2, #3, #4), perform registration and unregistration (#7). On the right side you find information about the currently selected field: the macro used for registration (#8) and the flag status (#5, #9).
Its main features are highlighted and explained below:
1. Summary information regarding registrations: no. of registered fields , total no. of fields in class, no. of errors, no. of warnings.
