Description |
Section A.9.3: defines the following BNF rules: arrayed_identifier ::= simple_arrayed_identifier | escaped_arrayed_identifier simple_arrayed_identifier ::= simpled_identifier [ range ] escaped_arrayed_identifier ::= escaped_identifier [ range ] Section A.9.3 further defines the BNF rule: module_instance_identifier ::= arrayed_identifier Section A.4.1 defines the BNF rule for module instance names: name_of_instance ::= module_instance_identifier [ range ] Given these sets of rules, it appears that a module instance name may have up to 2 range specifications following it. The first optional range comes from one of the rules simple_arrayed_identifier or escaped_arrayed_identifer, while the second optional range comes from the rule name_of_instance. According to section 12.1.2, only a single optional range is allowed. Similar issues arise from the BNF rules: name_of_udp_instance [Section A.5.4] and udp_instance_identifier name_of_gate_instace [Section A.3.1] and gate_instace_identifier |
Fix |
************************************************************ Shalom: Close this issue as being duplicated by #200. ************************************************************ Two possible fixes come to mind: 1) Change rule "name_of_instance" in section A.4.1 to be name_of_instance ::= module_instance_identifier which removes the optional range syntax, as it is already present in the syntax for module_instance_identifier. Or, replace all uses of "name_of_instance" with module_instance_identifier and remove rule name_of_instance. Do similarly for rules "name_of_udp_instance" and "name_of_gate_instance". 2) Change rule "module_instance_identifier" to be: module_instance_identifier ::= identifier which removes the option range from the syntax of a module_instance_identifier, since it is already present in the rule for "name_of_instance". Modify udp_instance_identifier and gate_instance_identifier similarly. This would remove all references to the BNF rules: arrayed_identifier which would in turn remove all references to the rules: simple_arrayed_identifier escaped_arrayed_identifier |
