Elements In Link Designer Apps

Descriptions of element icons in the Serial Link Designer and the Parallel Link Designer. Serial Link Designer elements are all differential.

ElementSymbolDescription
Resistor

Resistor symbol

Add a new resistor to the canvas.

Capacitor

Capacitor symbol

Add a new capacitor to the canvas.

Inductor

Inductor symbol

Add a new inductor to the canvas.

Lossless Transmission Line

Lossless transmission line symbol

Add a new ideal transmission line to the canvas.

The lossless or ideal transmission line is modeled using two parameters: impedance and delay. You can sweep these parameters over a range for design exploration.

The model on the schematic is based on typical etch corners. You can simulate the model for other etch corners. The parameters are then scaled for corner conditions specific for those corners. For more information on etch corners, see Specify Corner Conditions in Serial Link Design or Specify Corner Conditions in Parallel Link Design.

DC Voltage

DC voltage source symbol

Add a new two-port DC voltage source to the canvas.
Ground

Ground symbol

Add a new ground element to the canvas.
Subcircuit

Subcircuit symbol

Add a new subcircuit element to the canvas.

SPICE subcircuit models for passive elements must be present in the library before you can place on the schematic. The default project libraries for SPICE subcircuits are in si_lib/spice folder in the project.

S-Parameter

S-parameter symbol

Add a new S-Parameter element to the canvas. You can include S-Parameters that are in the Touchstone file format. Use the Import S-Parameters... option from the Library toolstrip menu to copy the S-Parameter to the library, create a wrapper and edit port maps.

For more information on how to use and edit S-Parameters, see Edit Imported S-Parameter Data.

Single-ended Via

Single-ended via symbol

Add a new single-ended via to the canvas.

You can create via models based on a stackup and via physical parameters. You have to specify the number of signal layers in the default stackup. You can modify the default via model using the via editor. For more information, see Via and Stackup Management in Serial Link Project or Via and Stackup Management in Parallel Link Project.

Differential Via

Differential via symbol

Add a new differential via to the canvas.

You can create via models based on a stackup and via physical parameters. You have to specify the number of signal layers in the default stackup. You can modify the default via model using the via editor. For more information, see Via and Stackup Management in Serial Link Project or Via and Stackup Management in Parallel Link Project.

Lossy Transmission Line

Single-ended lossy transmission line symbol

Add a new single-ended transmission line to the canvas.

The lossy transmission line is based on a frequency dependent RLGC model created by a 2-D field solver. The field solver has a transmission line editor for entering cross-section. Using the transmission line editor, you can either create a new model for the library or edit the model for an existing element on the canvas.

You can create a lossy transmission line based on the following model types:

  • Simple

  • Microstrip

  • Buried microstrip

  • Stripline

Differential Lossy Transmission Line

Differential lossy transmission line symbol

Add a new differential transmission line to the canvas.

The lossy transmission line is based on a frequency dependent RLGC model created by a 2-D field solver. The field solver has a transmission line editor for entering cross-section. Using the transmission line editor, you can either create a new model for the library or edit the model for an existing element on the canvas.

You can create a lossy transmission line based on the following model types:

  • Simple

  • Microstrip

  • Buried microstrip

  • Stripline

Differential Buffer

Differential buffer symbol

Add a new differential buffer designator to the canvas.

A schematic must have at least two designators: a transmitter and a receiver.

You can change the buffer model for a designator in three ways:

  • Edit Part/Pins dialog box,

  • Select IBIS File & Model dialog box,

  • and the default model menu items.

Differential Repeater

Differential repeater symbol

Add a new repeater/retimer designator element to the canvas.

A schematic must have at least two designators: a transmitter and a receiver.

You can change the buffer model for a designator in three ways:

  • Edit Part/Pins dialog box,

  • Select IBIS File & Model dialog box,

  • and the default model menu items.

HSPICE .param statement

HSPICE .param statement symbol

Add a new HSPICE .param statement to the canvas.
Differential Voltage Probe

Differential voltage probe symbol

Add a new differential voltage probe point to the canvas. Placing the probe symbol automatically creates a waveform node in the waveform file at the probed location.
Documentation Line

Documentation line

Add graphic line to panel
Documentation Circle

Documentation circle

Add a circle or an oval to the panel.
Documentation Box

Documentation box

Add a square or a rectangle to the panel.
External Documentation Link

Link to external documentation

Add a link to external documentation for reference.
