Editorial,
In reviewing the parser contract for IBIS 7.2, we found the following editorial
changes needed in IBIS 7.2 Draft 5:
This should be "string_literal" (lowercase) on page 248:
Parameter: Tx_Impulse_Input
Required: No, and illegal before AMI_Version 7.2
Direction: Tx
Descriptors:
Usage: Info
Type: String
Format: Value
Default: <String_literal>
Description: <string>
On page 286, the highlighted text has an extra ".":
Modulation_Levels Common Name
2 NRZ, PAM2
3 PAM3, Duobinary
4 PAM4
5 PAM5
....
8 PAM8
...
Required statement should be updated to suggested text in highlight on page 287:
Parameter: PAM_Thresholds
Required: Yes, illegal if Modulation_Levels is not specified.
Required: Yes, if Modulation_Levels is specified, illegal if
Modulation_Levels is not specified
On page 376 under [Designator Pin List] the highlighted text should be changed
to "may optionally be":
Usage Rules: The [Designator Pin List] keyword shall be followed by the
subparameter names "signal_name", "signal_type", and "bus_label", serving as
column headings. The keyword and the list of its subparameters shall be
followed by rows of information containing all designator pins references by
terminal lines found in all the EMD models contained by EMD Sets and referenced
by all EMD Groups found in the .emd file. Designator pin names which are not
referenced by any terminal line Qualifer_entry in any of the EMD models may be
optionally be listed under the [Designator Pin List] keyword.
Thanks,
