sc_port<> binding

[Effiong]

Hi all,

 

I created two modules with interfaces as below:

 

M1 :  sc_port<sc_fifo_out_if<T>, 0> a

M2 :  sc_port<sc_fifo_in_if<T>, 0> a2;

 

I have a third module which is also my top module i.e M3 and tried binding M1 output to M2 input to create a communication channel. I have tried using sc_fifo<T>  but it doesn't work.

 

How do I bind M1 output to M2 input inside M3 module?

 

Please not that T is a struct.

 

Thanks

Hi.

 

Normally, what you tried is correct. You should be able to bind the fifo to the two ports.

 

Maybe you can try again with int as T. If this works, you should check if the rules for T as stated in Section 6.23.3 of the SystemC LRM are fulfilled for your struct.

 

Greetings

Hello Sir,

I am afraid as SystemC at its core is a C++ library, all

the T can only be a primitive data type supported by

the core C++ language. To achieve your goal of fransferring

a struct between modules, you would have to create/

use a custom signal channel defined by you. This is

achieved simply by creating a buffer to hold the 

struct, and a blocking read/write scheme(using the

built-in SystemC sc_mutex, sc_semaphore etc.,) 

to ensure that the empty buffer cannot be read, and

no writes are possible during a read operation. Hope

that helps.
