Description

Creates a new parasitic inductance estimate model for a net. The model is star-shaped with an inductance connecting members to a central node. The members are the instance terminals connecting instances to the net. Also included are the terminals of the net. The member list provides an option to specify the list of instance terminals to include. If the members list is nil, all instances of the net are selected.

Arguments

d_cache	The parasitic cache in which the model or filter belongs. It includes a cache_id, which is returned by parCacheFind or parCacheGet for a SKILL list that contains library, cell, and view names.
?net t_net	Name of the net to create a resistance model for.
?type t_type	Type of estimate, that can be a star model or stitched extracted net.
?extLib t_extLib
	Library where the extracted view is located.
?extCell t_extCell
	Cell where the extracted view is located.
?extView t_extView
	Name of the extracted view.
?extNet t_extNet
	Name of net in extracted view.
?terminalMap l_terminalMap
	List of pairs mapping the terminals of the current design to those of the extracted design. Both elements of the colon-separated pair provide the instance and terminal name in the schematic namespace.
?include t_include
	Parasitics to be included. Possible values are `all`, `none`, `threshold`, or `lump`.
?threshold t_threshold
	If `include` = `threshold`, parasitics with values below the threshold will not be stitched into the estimate view.
?members t_members
	List of the instance terminal members of the net from which the inductance model is built. If the list is `nil`, all instance terminals of the net are considered. A member_list is a list of members where each member is a list in the form of `(design_object_name design_object_type [ parameter_list ])`.
?simParams l_simParams
	List of simulation parameters containing a name value pair for the parameter.
?simSweeps l_simSweeps
	List of simulation sweeps containing a name value pair for the parameter.
?name t_name	A string that uniquely identifies the model in the cache. If not specified, a name will be generated automatically.
?note t_note	A string note to be attached to the model.
?verbose g_verbose
	A boolean argument that controls whether a message is displayed to inform of the successful creation of a model. The default is `t`.

Value Returned

model_id	The `id` of the new estimate model.
`nil`	The model is not created.

Examples

The following example describes how to create a parasitic inductance model for net vdd!, where each inductance has a value of 5 henry.
