IBIS Electrical Board Description
Instantiates an IBIS Electrical Board Description (EBD) model name within the specified IBIS
file.
Syntax
_IO_xx file="path" ebd_model="ebd_model_name"
+ [ref_des_map='ref_des_1=instance_1 [,..., ref_des_n=instance_n]']
+ [ibischk_soft=NO|YES]
Parameters
• _IO_xx
IBIS instance name.
• file="path"
Specifies the path to the file that contains an IBIS formatted model.
This can be the full path (for example, /user/test/Models/model.ibs), a relative path, or just a
file name. Both / and \ should be acceptable as separators in the path name (for the UNIX
and NT versions). Avoid any spaces between the quotes and the file name/path. An Eldo
option IBIS_SEARCH_PATH is available to specify the path to the directory to search for
the IBIS files.
• ebd_model="ebd_model_name"
Specifies an IBIS Electrical Board Description (EBD) model name within the specified IBIS
file. ebd_model_name is case-sensitive.
• ref_des_map='ref_des_1=instance_1 [,…, ref_des_n=instance_n]'
Maps an IBIS buffer component to a reference designator, where:
o
o
instance_n is the name of the Eldo IBIS instance used to describe an IBIS
component.
ref_des_n is the reference designator visible in the Node sub-parameter of the [Path
Description] keyword in the EBD file.
Note
Reference designator name and instance name are case insensitive.
ref_des_map can be repeated more than once in the _IO_ card.
If a reference designator is repeated in the ref_des_map, then the instance assigned to
that reference designator will be that of the last one.
• ibischk_soft=NO|YES
Used to control the golden parser (ibischk) reporting of IBIS version compatibility errors.
Setting to NO means the IBIS version number is checked for compatibility. Only the first
