reading part of input port

[Mat]

I have recently started using SystemC for my project. I would appreciate if someone could help me with following problem.

 

How can I select part of input port in SystemC? In Verilog it can be done easily by choosing the required bits, e.g.,

inputPort[3:1]

 How can I do this in Systemc? I have defined an input port as follows 

sc_in < sc_int<5> > inputPort;

What is the syntax to read bits e.g., [1:3] from inputPort like I did in Verilog? I tried few  syntax like inputPort.read({1:3}) but no success.

Sorry, but this is simply not possible in the convenient manner of Verilog. Reason: SystemC is not about RTL. If you need a few bits, then read all of them and mask off the ones you want.

I managed to do this by defining the input port as sc_bv, i.e., 

sc_in<sc_bv<5>> inputPort; 

Then, using  ".range()" I can select part of  the port I need :

inputPort.read().range(0:2);

Well,  sc_int also support range access,  so you could do the same in original code.
