The following classes define the TLM port classes.
| TLM Port Classes | The following classes define the TLM port classes. |
| uvm_*_port #(T) | These unidirectional ports are instantiated by components that require, or use, the associated interface to convey transactions. |
| uvm_*_port #(REQ,RSP) | These bidirectional ports are instantiated by components that require, or use, the associated interface to convey transactions. |
These unidirectional ports are instantiated by components that require, or use, the associated interface to convey transactions. A port can be connected to any compatible port, export, or imp port. Unless its min_size is 0, a port must be connected to at least one implementation of its assocated interface.
The asterisk in uvm_*_port is any of the following
blocking_put nonblocking_put put blocking_get nonblocking_get get blocking_peek nonblocking_peek peek blocking_get_peek nonblocking_get_peek get_peek
Type parameters
| T | The type of transaction to be communicated by the export |
Ports are connected to interface implementations directly via uvm_*_imp #(T,IMP) ports or indirectly via hierarchical connections to uvm_*_port #(T) and uvm_*_export #(T) ports.
| uvm_*_port #(T) | |
| These unidirectional ports are instantiated by components that require, or use, the associated interface to convey transactions. | |
| Methods | |
| new | The name and parent are the standard uvm_component constructor arguments. |
The name and parent are the standard uvm_component constructor arguments. The min_size and max_size specify the minimum and maximum number of interfaces that must have been connected to this port by the end of elaboration.

The uvm_component class is the root base class for UVM components.
