Issue in downcasting to target_base_socket_type(downcasting to initiator_base_socket_type woks fine)

Hi Experts

 

I am facing an issue in downcasting the sc_module child objects to target_base_socket_type.

It works fine when I downcast to initiator_base_socket_type.

 

In initiator module I have following lines or code which works fine and tells me which ports are not bound

tlm::tlm_initiator_socket<BUS_WIDTH> initiator_socket;

typedef tlm::tlm_fw_transport_if<tlm::tlm_base_protocol_types> fw_interface_type;
typedef tlm::tlm_bw_transport_if<tlm::tlm_base_protocol_types> bw_interface_type;
typedef tlm::tlm_base_initiator_socket<BUS_WIDTH,fw_interface_type,bw_interface_type> initiator_base_socket_type;

void before_end_of_elaboration(){
    cout<<this->name()<<" before_end_of_elaboration"<<endl;
    std::vector<sc_object*> module_list = this->get_child_objects();
    for(std::vector<sc_object*>::iterator it=module_list.begin(); it<module_list.end();it++){
        initiator_base_socket_type* ibsoc = dynamic_cast<initiator_base_socket_type*>(*it);
        if(ibsoc != NULL){
            if(ibsoc->get_base_port().size()==0){
                cout<<"\t\t\tInitiator Port "<<ibsoc->name()<<" not connected"<<endl;
            }
        }
    }
}

 

 

I have the same piece of code (following) code in target module, in this case ibsoc is always NULL

tlm::tlm_target_socket<BUS_WIDTH,tlm::tlm_base_protocol_types,2> target_socket;

typedef tlm::tlm_fw_transport_if<tlm::tlm_base_protocol_types> fw_interface_type;
typedef tlm::tlm_bw_transport_if<tlm::tlm_base_protocol_types> bw_interface_type;
typedef tlm::tlm_base_target_socket<BUS_WIDTH,fw_interface_type,bw_interface_type> target_base_socket_type;
..
..
void before_end_of_elaboration(){
    std::vector<sc_object*> module_list = this->get_child_objects();
    for(std::vector<sc_object*>::iterator it=module_list.begin(); it<module_list.end();it++){
        target_base_socket_type* ibsoc = dynamic_cast<target_base_socket_type*>(*it);
        if(ibsoc != NULL){
            if(ibsoc->get_base_port().size()==0){
                cout<<"\t\t\tTarget Port "<<ibsoc->name()<<" not connected"<<endl;
            }
        }
    }
}

 

Am I missign something ?

Please note in for target port I have N=2

 

Thanks

Ok, I got the issue. I need to have same template parameters to make it work
