Old ARs: Arpad: Review the documentation (annotation) in the macro libraries. - deferred until a demand arises or we have nothing else to do 4) Analog BIRDs discussion - BIRD 144.3 Direct S-parameters under [External Model] (Cadence) - take a vote on whether to end the discussions on BIRD 144.3 in the ATM teleconferences and to make a recommendation to the IBIS Open Forum to reject the BIRD. - BIRD 145.2 Cascading [Model] with [External Model] (Cadence) - questions, comments? - BIRD 117.4/118.3 draft2 - introduction of changes in this draft (Arpad) - enclosed the tree in new IBIS keywords when the tree is inside the .ibs file - file name is now part of the parameter tree reference - included full "path" in the tree - still need to define rules for various parameter types - Reserved vs. Model_Specific - required vs. optional - questions/comments/discussion? - BIRD 116/144 related: The ATM group decided on 4/3/2012 that it is sufficient to describe the ideal nature of D_to_A and A_to_D converters as the boundary condition for models in [External Model] and [External Circuit]. - Find a good place in the specification to mention this. - Tx model is always driven by an ideal voltage source - i.e. zero output impedance - Rx model is always loaded by an ideal voltage source - i.e. infinite input impedance - Rx model's "A_to_D" converter is really an ideal probe which has an output of a floating point number - allowing multiple trees in one file is a good idea with keywords [Begin Parameter Trees] [End Parameter Trees] - eliminate 120 character line requirement inside these keywords? - use virtual file name instead of tree name? - separate the general syntax and rules of the tree from specific rules which apply to AMI or *-AMS and ISS models - BIRD 125 package modeling BIRD 122 (Walter) - working documents: ISS_Buffer_BIRD.doc (May 17, 2011) ISS_Package_BIRD_RevA.doc (May 27, 2011) 5) BIRD 121.1, data management parameters (file support) (Walter) - questions, comments? 6) BIRD 150, dependency table (Walter) - questions, comments? 7) New BIRD draft on Naming Rules (Walter) - comments, questions? 8) Info, Out, InOut BIRD (Arpad) - latest wording includes "in order to be compliant with this specification, Model_Specific parameters ... must not ...", and omits the word "simulation" so it's meaning doesn't have to be defined - any comments, questions on this draft? 9) Eye Mask definition 10) What is the purpose of the specification? Describe the syntax and rules of the syntax, or tell the reader how to make models?
