Cross Junction

Netlist Format

A cross instance has the following netlist format:

Axxx n1 n2 n3 n4 W1=val W2=val W3=val W4=val [NSUM=val]
COMPONENT=cross SUBSTRATE=substrate_name

n1, n2, n3, and n4 are the names of the nodes attached to the cross. The entry COMPONENT=cross identifies the element as a cross. The entry SUBSTRATE=substrate_name identifies the suspended stripline substrate model name selected for the design (see Selecting a Suspended Stripline Substrate). See the Suspended Stripline (SS) Substrate for information on this substrate type.
