How to make sure external power supplies are connected if required, or internal supplies are used. Much discussion about various possible implementations. "select" state does not change during simulation. Resolution: Right now, "case" must get its values from the IBIS keywords. Make it more general, and let user/tool pick any valid "case" value. Add attribute, data type of "enumerated list", noting [ ] => a keyword in the IBIS data file, anything else is part of model definition. Lynne - put the "select" variable name as a parameter on the [Define Model] statement? John: [Pin Mapping] has no macro right now. (Whole component/pinlist/pkg values is open.) > -- Tline 'ref1' nodal format compatibility with N-port matrix > (further discussion) Rlcg matrix in HSpice: 3 conductors + reference, 3x3 matrix. Known convergence problems if ref node is not at same DC bias at both ends. Resolution: # rows in Rlcg matrix = number of inputs and outputs. Node list includes ref1 and ref2 for consistency with Spice format. Attached to node number "0" (global ideal ground). Document node "0" is not the same as node "gnd". >IBIS-ML Spec Review 90min All > -- review latest spec (IBIS-ML_06) > -- outline of chapter 6 pg 11 - add in the remaining circuit elements (trigger, alarm, driver, delay). AR: John - Look at Al's list (reshape, invert, others in 3.2). Table 3 & descriptions - V cannot depend on itself, ditto I. <,| > for node lists. OPEN: When trigger is "false", "time-trigger" evaluates to "time". Using trigger=0 initially may present problems, but so does "NA". Put in Stephen's updates to 5.4-5.6. Section 6 limit to expressions. No mention of functions. Talk about what an expression is, what an equation is, logical and math operators. Expressions to create a value Relational operators (if/else) How deeply does this doc get into matrices? Ref to another spec? Put it in here? Don't want copies of the same info in two different places. Put datatypes chapter ahead of expressions chapter. Chapter 8 - add keywords, parameters, subparameters. >Next Meeting Plans Date: Thursday Nov 15, 2001 Time: 2:00 - 4:00 PDT Dial-In Number: 1-408-894-3000 (Meeting Place) Meeting ID: 42479 (IBISX) Respectfully submitted, Lynne Green
