Review of the Touchstone draft continued. Bob noted that the square bracket characters are used in two senses in the document. This may not require changes. Bob also noted that [Version] should not be required for 1.0 files; only 2.0 should be needed, as a text string rather than floating point. Addition of a [Number of Ports] keyword is needed, as the overall number of ports cannot be inferred from the text's arrangement. Similarly, either the number of data columns should be specified or some regularity on carriage returns/line feeds (line lengths) should be enforced. Finally, the team noted that the updated reference keyword should be first, before all other keywords aside from [Version]. Team Objectives: 1) complete ICM-IBIS linking BIRD and any associated changes to the ICM specification 2) update the ICM specification, if needed, to clarify the mapping of ICM nodes to S-parameter ports 3) complete a specification for "Touchstone Plus" or similar industry-standard definition for Touchstone-like files, to include complex impedance references, removal of limits on the maximum number of ports and per-port impedance references
