Use this to match together components whose tolerances track.
Matched components are used when running a Monte Carlo Simulation.
Some devices such as resistor networks are constructed in a manner that their tolerances track. Such devices often have two specifications one is an absolute tolerance and the other a matching tolerance. The matching tolerance specifies the matched devices will always be within a certain tolerance of each other.

How To Match Components
Select the component(s) that you wish to change. If all resistors or capacitors are to be matched, use the Select All Resistors or Select All Capacitors options from the Monte Carlo sub-menu on the Simulation menu.
Now use the Match Components option from the Monte Carlo sub-menu on the Simulation menu.
The following dialog will be displayed:
Type a ‘lot’ name to be applied to the selected components in order to make them matched. The name which must be unique. You can use any alphanumeric name.
If the value is initially set to
If using device tolerance parameters, note that any absolute tolerance specified must be the same for all devices within the same match group. Any devices with the same match name but different absolute tolerance will be treated as belonging to a different match group by the simulator.
Note that the components will only be matched if they all refer to the same model. Any components with the same match name but referring to a different model will be treated as if they belong to a different match group by the simulator.
Next use Set Match Tolerance to set the selected components relative tolerance.
