All, I have reviewed Bob's comments, and am enclosing a response with my comments. I am in agreement with all of Bob's comments, except the treatment of the first column in each row. With my proposal, the format of single row tables and multi row tables are the same, and by treating the first column of each row as a "parameter", then is satisfies all of the DLL BNF rules. The alternative is to treat single row tables differently than multi row tables. I will accept the decision the IBIS-ATM, my real goal here is to not need to have context sensitive parsers in either the EDA tool, or models.
