DVM: Jumper

The Jumper column allows you to specify the state of a jumper or series of jumpers on the top-level schematic. This column is useful for making changes to the schematic topology when the components cannot be altered with a Var(), GlobalVar(), or Change() function.

The jumper symbols have either one or two positions and can have up to 64 poles. Through the testplan, jumper positions can be changed on a test-by-test basis to provide additional flexibility in configuring the schematic.

The process for using jumpers consists of two basic additions to the testplan.

Inserting a column with a Change() function in the header.
In each test row for that column, adding an Open() or Close() function with a list of jumper reference designators, using the following syntax for the one-position jumper:

Open(refdes₁, refdes₂,...refdes_n)
Close(refdes₁, refdes₂,...refdes_n)

If you use two-position jumpers, the syntax is the same, but you use the following functions:

Open(refdes1, refdes2,...refdesn)
Pos1(refdes1, refdes2,...refdesn)
Pos2(refdes1, refdes2,...refdesn)
where Close() is a synonym for Pos1().
