Open Stub, Physical Length


 

[spacer]

Netlist Format

An instance of a coplanar waveguide open stub, physical length has the following netlist syntax:

Axxx n1 [W=val] [G=val] [P=val] [GAP=val]
COMPONENT=cpw_open_stub_physical SUBSTRATE=substrate_name

n1 is the name of the node attached to the open stub. The entry COMPONENT=cpw_open_stub_physical identifies the element as a coplanar waveguide open stub, physical length.

The SUBSTRATE=substrate_name is the coplanar waveguide substrate model name selected for the design (see Selecting a Coplanar Waveguide Substrate for details).
