[sv-bc] Packed dimension [0:0] - What should happen?

Hi, All -

Question for you regarding packed dimensions that are only one-wide

I seem to recall that Shalom entered a clarification of what should 
happen when a packed dimension resolves to [0:0] after passing 
parameters (I'm not sure if Shalom is on vacation this week due to an 
Israeli holiday or not).

I am teaching a SystemVerilog class this week and this issue has come 
up. The engineers say that some tools are dropping a packed dimension 
that includes [0:0] but that their parameterized code wants to 
reference the packed dimension.

Is there a Mantis item on this or have any of you run into this yourself?

Thanks.

Regards - Cliff
