Kumar,
From pages 186/187 of IBIS 5.0
| The syntax for this string is:
|
| 1. Neither names nor individual values can contain white space characters.
| 2. Parameter name/value pairs are always enclosed in parentheses, with the
| value separated from the name by white space.
| 3. A parameter value in a name/value pair can be either a single value or a
| list of values separated by whitespace.
| 4. Parameter name/value pairs can be grouped together into parameter groups
| by starting with an open parenthesis followed by the group name followed
| by the concatenation of one or more name/value pairs followed by a close
| parenthesis.
| 5. Parameter name/values pairs and parameter groups can be freely
| intermixed inside a parameter group.
| 6. The top level parameter string must be a parameter group.
| 7. White space is ignored, except as a delimiter between the parameter name
| and value.
| 8. Parameter values can be expressed either as a string literal, decimal
| number or in the standard ANCI 'C' notation for floating point numbers
| (e.g., 2.0e-9). String literal values are delimited using a double
| quote (") and no double quotes are allowed inside the string literals.
| 9. A parameter can be assigned an array of values by enclosing the
| parameter name and the array of values inside a single set of
| parentheses, with the parameter name and the individual values all
| separated by white space.
Note 2. above:
| 2. Parameter name/value pairs are always enclosed in parentheses, with the
| value separated from the name by white space.
The following (from Ambrish and Ken) follow this rule:
(abc 10.1 20.2 30.3 )
The following example that you propose for multi-row tables violates this rule:
(name (a11 a12 a13) (b11 b12 b13))

a single row table can be passed as
(name a11 a12 a13)
multi rows
(name (a11 a12 a13) (b11 b12 b13))

Ken,
A Table, by definition, supports multiple rows. How would you pass the
following?
(abc (Usage In) (Type Float) (Format Table (10.1 20.2 30.3) (1. 2. 3.)
(4.
5. 6.)) (Description "Table example"))
It is this case that makes Format Table as a Usage In, InOut or Out
parameter problematic, and not defined, or allowed in the IBIS 5.0
definition of the AMI_parameters_in or AMI_parameters_out string
definition.
We need to pass similar types of data into the DLL's that we write; we
chose
to do this in the following manner:
(abc (Usage In) (Type String) (Format Value "10.1 20.2 30.3")
(Description
"Alternative example"))
Here is what it looks like when being passed to the DLL:
(abc "10.1 20.2 30.3")
Your method satisfies all of the rules defined in pages 186 and 187, as
long
as the Table only contains one row.
I think there are the following options:
1. Allow a Format Table to have Usage In (or InOut, or Out), but require
that such a Table have only one Row.
2. Require that Format Table has (Usage Info)
Option 1 requires some work by all of the other EDA vendors, and a
clarification to the definition of Format Table.
Option 2 requires some work by Sigrity, and a clarification to the
definition of Format Table.
Does anyone have any other (preferably better) ideas?

Hi,
Following up from the last call, here is an example of Table being used
in
an AMI file:
(abc (Usage In) (Type Float) (Format Table (10.1 20.2 30.3))
(Description
"Table example"))
Here is what it looks like when being passed to the DLL:
(abc 10.1 20.2 30.3 )
Thanks,
