ISSUE TITLE: IBIS-AMI Section 6c Tables Update
REQUESTER: Bob Ross, Teraspeed Consulting Group
DATE SUBMITTED: June 15, 2011
DATE REVISED:
DATE ACCEPTED BY IBIS OPEN FORUM:
******************************************************************************
******************************************************************************
STATEMENT OF THE ISSUE:
Tables 1, 2, and 3 need updating for ambiguities (NA?), incorrect settings,
and a retired or new Reserved Parameters. The proposal shows replacement
changes with |* lines.
The changes are documented in the ANALYSIS PATH/DATA THAT LED TO SPECIFICATION
section below.
The needed Reserved Parameter changes in Tables 1-3 are based on BIRD120
(to add AMI_Version) and BIRD126 (to remove Use_Init_Output).
******************************************************************************
STATEMENT OF THE RESOLVED SPECIFICATIONS:
Replace this test:
| The general rules, allowed usage and a brief summary of the
| data types and data formats allowed for each reserved
| parameter is presented in the following tables.

******************************************************************************
ANALYSIS PATH/DATA THAT LED TO SPECIFICATION
Corrections and additions:
1. AMI_Version added to the table per pending approval of BIRD126
2. Use_Init_Output - note for removal for IBIS Version 5.1 per BIRD120
3. Ignore_Bits (not valid for 'Out', as previously documented)
4. '--' replaces NA since NA can be confused with an 'NA' reserved word
5. Table 3 vertical data format titles are spelled out correctly
(Increment, Gaussian, Dual-Dirac)
BIRD120 and 126 changes are included here related to AMI_Version and
the removal of Use_Init_Output for IBIS Version 5.1 and above.
*****************************************************************************
ANY OTHER BACKGROUND INFORMATION:
New reserved parameters could be inserted into these tables, but it might
be clearer in the future to document related groupings of parameters into
separate sets of tables (e.g., jitter and noise parameters).
