Walter and All, Looking at that paragraph on pg. 4 in the v5.1 specification, I noticed something else that needs to be changed, now that we have a Word formatted "IBIS Specification". Notice that in the original text, this "specification" was not considered a specification. Notice the first paragraph of chapter 2: "In order to enable an industry standard method to electronically transport IBIS modeling data between semiconductor vendors, EDA tool vendors, and end customers, this template is proposed. The intention of this template is to specify a consistent format that can be parsed by software, allowing EDA tool vendors to derive models compatible with their own products." This is talking about the IBIS specification file as an "ASCII template", not a specification. Recall that the reason we had comment lines at the beginning of each line that was not an example was that it was supposed to work as a model in the parser and in a simulator. This is actually captured in the above quote too. Now that our "ASCII template" is not ASCII anymore, we will have to revise all text in the Word formatted "IBIS Specification" that refers to itself an "ASCII template". Thanks, Arpad ================================================================= From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Walter Katz Sent: Tuesday, September 25, 2012 5:05 AM To: IBIS-ATM Subject: [ibis-macro] Deprecation BIRD All, There are a number of items within the IBIS specification that are not being used in the industry. Maintaining support for these items is a burden on both EDA companies and the ability for IBIS to advance the standard to "to allow accurate modeling of new, or other I/O buffer structures." I am submitting this Deprecation BIRD as an amendment to the "Commitment to Backward Compatibility" clause that allows items to be removed from the IBIS specification and introduces a formal deprecation process.
