Re: [sv-ac] problem with Mantis 2150 -automatic variables in action block ?

Hi Ed,

I suspect that you may have a misunderstanding about automatic variables.
The following is contained in 6.21. There are more details contained in
that section which might help clarify things for you. I believe that you
are confusing "automatic variables" with "dynamic variables".

"Data declared inside a module, interface or program, but outside a task, process,
  or function, are local in scope and static in lifetime (exist for the lifetime
  of the module, interface or program). This is roughly equivalent to C static
  data declared outside a function, which is local to a file."
