How to implement b_transport method for two tlm_target_sockets in one module?

[Randy Suen]

Hello everyone,

I have defined a module like this:

class module_a : public sc_module, public  tlm_fw_transport_if<>{

tlm_target_socket target_1;

tlm_target_socket target_2;

......

void b_transport(tlm_generic_payload& trans, sc_time& delay);

}

Here module_a has two tlm_target_sockets target_1 and target_2. Since tlm_target_sockets has no callback register, I have to implement the virtual function b_transport in the module definition for any initiator_sockets binded these target sockets. However, I wish target_1 and target_2 have different actions when b_transport is called. So Is there any way to implement two different b_transport methods for target_1 and target_2 respectively?

Use a TLM tagged socket from the utilities. There are several to choose from. They allow you to register the method of choice or you can use the tag to differentiate.

Thanks Black.

What if I also need child-to-parent binding? Does it mean that multi_passtrough_target_socket is the only choice?
