IBIS Models Support in Eldo
IBIS Component
0 or OFF
No package is added.
1 or CMPNT
RLC components defined under [Package] keyword are added.
2 or PIN
RLC components defined under [Pin] are added.
3 or PKGMOD
A package model will be used. This is the default.
4 or MIX
A package model will be used, and RLC parasitics are added as defined under [Pin]
section for pins that are not defined in the package model.
Note
If no data is available for selected packaging type, then the data in the lower type
will be used.
• pkg_model="package_model_name"
Specifies an IBIS package model name within the specified IBIS file. The package model
name must match one defined for this component under [Package Model] or [Alternate
Package Models] keywords. If pkg_model is not specified, the one under [Package Model]
will be used. “package_model_name” is case-sensitive.
• ss_group='ON|OFF G1 [,G2, ...]'
Sets the On/Off state for the series switch buffers created according the info under [Series
Pin Mapping] keyword.
You can set the logical state of this set of groups by type ON|OFF in the beginning of the
set, and then follow it by the groups’ names that will take this state. The specified set of
groups must match one of these under [Series Switch Groups] keyword or its
complementary. If ss_group is not specified Eldo will take the first set of groups under
[Series Switch Groups] keyword to set the logical state for the series switch buffers.
• nopseudo
When specified Eldo does not generate pseudo-differential buffers for the pseudodifferential
pins, and generates single-ended buffers instead.
By default Eldo generates pseudo or true differential buffers as defined under [Diff Pin]
keyword.
Note
The following keywords are used in the generated buffers if applicable.
