Hello AMI experts, I stumbled on a question regarding how Format Corner supposed to be interpreted by an EDA tool. Pg. 140 of the IBIS specification say this: and pg. 141 has this: Then on pg. 146 I see this: and on pg. 147 I see this: In BIRD 124 I read the following: | "[Corner]" is a predefined AMI parameter of Type String and Usage Info that can | be used to create an input column in a dependency table. It has a List format with | the allowed values "Typ", "Slow" and "Fast". but I don't see any text in the Specification or the BIRD that explains how "Corner" is predefined and from where and how it gets it value. Could someone explain this to me please? It seems that this needs another clarification BIRD... Thanks, Arpad ===============================================================
