Hi,
I my UVM environment, when i am using non-blocking assignments(NBA) in driver it is supporting but when I use it in scoreboard it is giving an error. Why so?

Why NBA is supported in driver and not in scoreboard?

With regards,
Tarun

In reply to perumallatarun:

It would help to show the error message and the statement causing the error.

SystemVerilog has restrictions on what can be assigned using an NBA based on a number of different things. No NBA’s to

  • any nets
  • variables with automatic lifetimes
  • elements of dynamic arrays, queues, or associative arrays.

So you also need to show us how the variable you are trying to do an NBA is declared.
