Constructors
- function new ( string name ) [source]
Create an instance of this class
Create an instance of the user-defined backdoor class for the specified register or memory
Functions
- virtual function void read_func ( uvm_reg_item rw ) [source]
User-defined backdoor read operation.
Peek the current value in the HDL implementation. Returns the current value and an indication of the success of the operation. Read_func
- virtual function bit is_auto_updated ( uvm_reg_field field ) [source]
Indicates if wait_for_change() method is implemented
Implement to return TRUE if and only if wait_for_change() is implemented to watch for changes in the HDL implementation of the specified field. Is_auto_updated
- function void start_update_thread ( uvm_object element ) [source]
Start_update_thread
- function void kill_update_thread ( uvm_object element ) [source]
Kill_update_thread
Tasks
- virtual function write ( uvm_reg_item rw ) [source]
User-defined backdoor write operation.
Call do_pre_write(). Deposit the specified value in the specified register HDL implementation. Call do_post_write(). Returns an indication of the success of the operation. Write
- virtual function read ( uvm_reg_item rw ) [source]
User-defined backdoor read operation.
Overload this method only if the backdoor requires the use of task.
Call do_pre_read(). Peek the current value of the specified HDL implementation. Call do_post_read(). Returns the current value and an indication of the success of the operation.
By default, calls read_func(). Read
- virtual function pre_read ( uvm_reg_item rw ) [source]
Called before user-defined backdoor register read.
The registered callback methods are invoked after the invocation of this method.
- virtual function post_read ( uvm_reg_item rw ) [source]
Called after user-defined backdoor register read.
The registered callback methods are invoked before the invocation of this method.
- virtual function pre_write ( uvm_reg_item rw ) [source]
Called before user-defined backdoor register write.
The registered callback methods are invoked after the invocation of this method.
The written value, if modified, modifies the actual value that will be written.
- virtual function post_write ( uvm_reg_item rw ) [source]
Called after user-defined backdoor register write.
The registered callback methods are invoked before the invocation of this method.
Base class for user-defined back-door register and memory access.
This class can be extended by users to provide user-specific back-door access to registers and memories that are not implemented in pure SystemVerilog or that are not accessible using the default DPI backdoor mechanism.
