True. That's better way of doing this. Just thought of that after sending the earlier mail. Thanks Kausik From: Bresticker, Shalom [mailto:shalom.bresticker@intel.com] Sent: Thursday, December 05, 2013 7:18 PM To: Datta, Kausik; 'SV_BC List' Subject: RE: [sv-bc] use before declaration But it seems to me that when the compiler reach the declaration of t, there are only two possible conclusions: either t was referenced before its declaration, or there is a duplicate declaration. Shalom From: Datta, Kausik [mailto:Kausik_Datta@mentor.com] Sent: Thursday, December 05, 2013 15:45 To: Bresticker, Shalom; 'SV_BC List' Subject: RE: [sv-bc] use before declaration Hi This is because of compiler can only check for this error after reaching endmodule and that check will be based on the relative position of "t.s" and "t" if they are in the same file or relative time of processing of "t.s" and "t" by the compiler if they are in different files. I don't think compiler developers will like to add this checking in code.

Looks that (bacause of identical syntax) tool's have problem with that. BTW "non-hierarchical " supervene only one time in LRM. Maybe this word should be changed or Glossary should be updated , Radek ________________________________ From: owner-sv-bc@eda.org<mailto:owner-sv-bc@eda.org> [mailto:owner-sv-bc@eda.org] On Behalf Of Bresticker, Shalom Sent: Thursday, December 05, 2013 1:42 PM To: SV_BC List Subject: [sv-bc] use before declaration Hi, Why does the following not fail compilation? module test; wire w = t.s ; struct { logic s; } t; endmodule 6.21 says, "A variable declaration shall precede any simple reference (non-hierarchical) to that variable." The reference to t is non-hierarchical, isn't it?
