If the correspondence between pin names and nodes is as follows: then the template looks like this: X^@REFDES %IN+ %IN- %OUT+ %OUT- @MODEL The rules of agreement (rules for pin callout in subcircuit templates) are outlined in the following figure. Table 5-6 This node name... Corresponds to this pin name... 10 IN+ 3 IN- 27 OUT+ 2 OUT- must must must must Number of nodes in first line of subcircuit definition Sequence of nodes in first line of subcircuit definition Number of pins called out in template Sequence of pins called out in template Number of modeled* pins shown in part Names of pins called out in template Names of modeled* pins shown in part * Unmodeled pins may appear on a part (like the two voltage offset pins on a 741 opamp part).
