Paths Connected by Series Resistors as Differential Terminators – [Reference Designator Map] Keyword: Yes, if any of the path descriptions use the Node subparameter Required: Maps a reference designator to a component or electrical board description Description: contained in a .ibs or .ebd file. The [Reference Designator Map] keyword must be followed by a list of all of the Usage Rules: reference designators called out by the Node subparameters used in the various path descriptions. Each reference designator is followed by the name of the .ibs or .ebd file containing the electrical description of the component or board, then the name of the component itself as given by the .ibs or .ebd [Component] or [Begin Board Description] keyword respectively. The reference file’s designator, file name and component name terms are separated by white space. By default the .ibs or .ebd files are assumed to exist in the same directory as the calling .ebd file. It is legal for a reference designator to point to a component that is contained in the calling .ebd file. The reference designator is limited to ten characters. Example: [Reference Designator Map] | | External Part References: | | Ref Des File name Component name u23 pp100.ibs Processor u24 simm.ebd 16Meg X 36 SIMM Module u25 ls244.ibs NoName 74LS244a u26 r10K.ibs My_10K_Pullup [End Board Description] Keyword: Yes Required: Marks the end of an Electrical Interconnect Description. Description: This keyword must come at the end of each complete electrical interconnect model Usage Rules: description. Optionally, a comment may be added after the [End Electrical Description] keyword to clarify which board model has ended. Example: [End Board Description] | End: 16Meg X 8 SIMM Module Keyword: [End]
