Abstract:

This is a depth-first ordered VHDL syntax summary with annotated semantics and corresponding paragraph numbers to VHDL and Ada Reference Manuals. The BNF representation of VHDL is cross-referenced to comparable VHDL and Ada syntax and semantic descriptions within the VHDL and Ada language reference manuals LRM. This product resulted from the first step of developing a VHDL to Ada interface. This ordering of the BNF representation of VHDL should help reduce the time for new VHDL implementors and programmers to overcome the robustness of the VHDL syntax and semantics. It could serve as an implementors guide for developing VHDL software tools and help VHDL programmers remember the details of the VHDL syntax and semantics without having to thumb through the scattered bits and pieces of syntax scattered in the syntax summary of the reference manual. This VHDL Summary could also help insure validation test coverage by aiding the validation test writer to keep track of each detail incorporated in the VHDL language. The annotated semantics consist of brief descriptions to serve as reminders.
