=== Defining Lumped Active & Passive Devices ===
In [[EM.Tempo]], you can define four types of lumped devices:

EM.Tempo also provides two multiport network devices:

# '''[[Glossary of EM.Cube's Materials, Sources, Devices & Other Physical Object Types#Resistor | Active One-Port]]'''
# '''[[Glossary of EM.Cube's Materials, Sources, Devices & Other Physical Object Types#Capacitor | Active Two-Port]]'''
Â
These devices are rather distributed and their behavior is similar to a microstrip port source. In other words, the active one-port requires a rectangle strip object as a host, while the active two-port requires two rectangle strip objects for its definition. The circuit behavior of these devices is defined by a Netlist file. Their property dialog provides a text editor for simply writing the Netlist description of the device. You can also import an existing external Netlist file with a ".CIR" file extension.
Â
{{Note|[[RF.Spice A/D]] can generate a Netlist file corresponding to an existing circuit project. The Netlist file can then be save to a text file with a ".TXT" file extension. When importing such files to EM.Tempo, you need to change the file extension to ".CIR".}}
