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) - define boundary conditions for unused ports - define boundary conditions for connected ports - does [External Model] allow additional terminals? (No) - BIRD 145.2 Cascading [Model] with [External Model] (Cadence) - questions, comments? - 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]. We now need to 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 117/118 revision to generalize parameter file references - questions/comments/discussion (Arpad) - enclose the tree in IBIS keywords if it is inside the .ibs file and move it before the [End] keyword - make the file name part of the parameter tree reference - need to define rules for various parameter types - Reserved vs. Model_Specific - required vs. optional - 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?
