Parameters:

name (string)

Tasks

virtual function

pre_write(uvm_vreg_field field, longint unsigned idx, uvm_reg_data_t wdat, uvm_path_e path, uvm_reg_map map)

Task

pre_write

Callback called before a write operation.

The registered callback methods are invoked before the invocation of the virtual register pre-write callbacks and after the invocation of the uvm_vreg_field::pre_write() method.

The written value wdat , access path and address map , if modified, modifies the actual value, access path or address map used in the register operation.

Parameters:

• field (uvm_vreg_field)

• idx (longint unsigned)

• wdat (uvm_reg_data_t)

• path (uvm_path_e)

• map (uvm_reg_map)

virtual function

post_write(uvm_vreg_field field, longint unsigned idx, uvm_reg_data_t wdat, uvm_path_e path, uvm_reg_map map, uvm_status_e status)

TASK

post_write

Called after a write operation

The registered callback methods are invoked after the invocation of the virtual register post-write callbacks and before the invocation of the uvm_vreg_field::post_write() method.

The status of the operation, if modified, modifies the actual returned status.

Parameters:

• field (uvm_vreg_field)

• idx (longint unsigned)

• wdat (uvm_reg_data_t)

• path (uvm_path_e)

• map (uvm_reg_map)

• status (uvm_status_e)

virtual function

pre_read(uvm_vreg_field field, longint unsigned idx, uvm_path_e path, uvm_reg_map map)

TASK

pre_read

Called before a virtual field read.

The registered callback methods are invoked after the invocation of the virtual register pre-read callbacks and after the invocation of the uvm_vreg_field::pre_read() method.

The access path and address map , if modified, modifies the actual access path or address map used in the register operation.

Parameters:

• field (uvm_vreg_field)

• idx (longint unsigned)

• path (uvm_path_e)

• map (uvm_reg_map)

virtual function

post_read(uvm_vreg_field field, longint unsigned idx, uvm_reg_data_t rdat, uvm_path_e path, uvm_reg_map map, uvm_status_e status)

TASK

post_read

Called after a virtual field read.

The registered callback methods are invoked after the invocation of the virtual register post-read callbacks and before the invocation of the uvm_vreg_field::post_read() method.

The readback value rdat and the status of the operation, if modified, modifies the actual returned readback value and status.

Parameters:

• field (uvm_vreg_field)

• idx (longint unsigned)

• rdat (uvm_reg_data_t)

• path (uvm_path_e)

• map (uvm_reg_map)

• status (uvm_status_e)
