All, 1) The unit of UI are unitless. 1==bit_time, .5==bit_time/2, . 2) Four Gaussian, mean and sigma are both either Type Float (second) or Type UI depending if Type is set to Float or UI respectively (see answer to 1). We are allowing multiple Type fields for Table, but not for Gaussian, DjRj or Dual-Dirac. 3) I do not understand the question, please clarify by an example other than Description. Walter From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Muranyi, Arpad Sent: Sunday, March 18, 2012 12:10 PM To: 'IBIS-ATM' Subject: [ibis-macro] Questions from the Editorial Group Hello everyone, A few questions were raised in the Editorial Task Group for I would like to get answers for from our experts. 1) What units are assumed for UI? Seconds? Picoseconds? Percent? Other? We are assuming no suffixes are allowed. 2) For Gaussian and similar types, are we assuming "mean" and "sigma" are floats? 3) Do the rules under "Type" apply to all of the fields in an IBIS-AMI .ami file? In other words, do arguments other than "Type" need to follow the same rules as their corresponding type? For example, is the argument to Description a string? If so, does the argument follow the same rules as the formal type "string"? We only defined the rules for the *Types* string, Boolean, Integer, etc., but other AMI file contents are apparently of these types without being Type arguments. Answers and comments are encouraged to help the Editorial Group in finalizing the v5.1 specification. Thanks, Arpad ============================================================
