Input port array and driving input port value on output pin

[Minu]

Suppose I have many input ports and one output port on which I want to drive the input port no which was selected.I wrote like this:

 Vector<sc_port<sc_signal_in_if<bool>>>input_port;

Sc_out<int>output_port;

After that applied for loop and write I index to output_port.

But here the problem is in one cycle if I selected 5th input port then on output port ,the 5 will display.In second cycle if I selected 2th import port then it will display 5 and 2.which is not correct it should be 2 only.

So how we can achieve  this functionality?

Without any code this is impossible to answer. You may use https://www.edaplayground.com/ for this or post it here.

Hi,

I have somehow  written code on eda playground

But here the problem is in one cycle if I selected 5th input port then on output port ,the 5 will display. In second cycle if I selected 2th import port then it will display 5 and 2.which is not correct it should be 2 only.

This scenario has been asked by one senior. I am unable to find out the exact way how this issue can be resolved.

Hello @Minu,

The shared code does not seem to be correct.

Is it the same code you are trying to run? I don't seem to locate the initialization of the sc_vector correctly under testbench?

It would be better if could also share some context about design along with the relevant source.
