Re: Analog function question

Hi Arpad,

I think i understand the problem a bit more.

I also checked the input_declaration BNF syntax and the syntax for this 
is specified in one of the sections (7.4.2.2) but not in the BNF/Annex A
input_declaration :=  input [range] list_of_port_identifiers;

Also the BNF for list_of_port_identifiers is not specified in BNF syntax.

This needs to be fixed as part of the next revision. I will raise a 
mantis item for this if its not already there. Anyway i would expect 
this to be resolved as part of moving to 1364-2005.

cheers,
Sri
