Detailed Description
template<typename IN = int, typename OUT = uvm_sequence_item>
class pk_utils_uvm::filter_trfm< IN, OUT >
Base class for a filter transformation.
If type IN is a subtype of uvm_sequence_item, this filter transforms simply performs an identity transform by upcasting the input item to a uvm_sequence_item If another transformation is desired, extend the class and override the evaluate and transform methods
- Parameters
-
IN Input type of objects to transform OUT Output type of transformed objects

Member Function Documentation
◆ evaluate()
|
virtual |
Evaluates whether the input should be transformed and forwarded, or whether it should be discarded.
If the method returns 0, the input item is discarded and may not be retrievable
- Returns
- 1 if the item should be transformed and forwarded, 0 otherwise.
Definition at line 49 of file pk_utils_uvm.sv.
◆ transform()
|
virtual |
Transforms the item of type IN to one or more items of type OUT.
- Parameters
-
t The input object which should be transformed items A reference to an array where output items will be returned. If the handle is to an existing array, that array will be lost.
Definition at line 40 of file pk_utils_uvm.sv.
◆ write()
| void pk_utils_uvm::filter_trfm< IN, OUT >::write | ( | IN | t | ) |
This filter transform's write-implementation from uvm_subscriber When items are written to the filter transform, they are first evaluated with evaluate to decide whether a transformation should occur.
If true, they are transformed with transform, and all output items are then written out on ap
- Parameters
-
t The item written to this filter transform
