Hi,
While simulating my top_module,i was getting a run time error just at the start of simulation & simulation stopped.
It was showing a breakpoint at line below:
To understand what those variables mean,i've attached a part of my code:
Is there anything wrong with concatenation or is it any other problem ?

Hi,
It was very foolish of me to make this mistake.
The datawidth of left hand side & right hand side do not match in that line.
c0_app_wdf_data is 192 bits while right side is 184 bits,so it is showing a run time error.
