# How much does CircuitLab cost?

## How much does CircuitLab cost?

Instructors are given free access to these capabilities; for students, the cost is around \$12. CircuitLab has two modes of functionality: Build Mode and Simulation Mode.

How do you use a voltmeter in CircuitLab?

The Voltmeter and Ammeter elements can be used to display the voltage across or the current through the element on the schematic. You can double click a Voltmeter or Ammeter element to bring up the Parameters Box where you can select “Show Voltage” or “Show Current”.

How do you measure current in a circuit lab?

Hover your mouse over one of the leads of an element (say a resistor). The mouse cursor will turn into a pen and you will see current displayed at the bottom right corner of the editor.

### Is CircuitLab free for students?

My school, college, or university is already a member of the CircuitLab Academic Institution Program. Your school pays us for a site-wide license membership, so you can get free access to CircuitLab Student Edition using the button above once you’ve confirmed your official email address.

What is the equivalent circuit for HSPICE?

HSPICE Example: DC Sweep, and Thevenin Equivalent Circuit This is the same example as the previous one but written for HSpice. The inputs can be the same for both PSpice and HSpice.

How to use the sweep command for DC analysis?

For DC analysis, the simplest sweep command has the following format (values between [] are optional): Elements var1 and var2 may be an independent source (voltage or current), a parameter or the word TEMP (for a temperature sweep). For the double sweep, the sweep of var1 is repeated for each value of var2.

#### What is the difference between DC and AC sweep?

With DC sweep, you get an accurate representation of how the circuit performs as one of the independent sources is varied. With AC sweep, you can calculate the small-signal response of a circuit. In future blogs, we’ll be looking at our final simulation method, transient point analysis.

What is HSPICE?

DEPARTMENT OF ELECTRICAL ENGINEERING HSPICE Example: DC Sweep, and Thevenin Equivalent Circuit This is the same example as the previous one but written for HSpice. The inputs can be the same for both PSpice and HSpice. However, HSpice allows you to name nodes instead of numbering the nodes.
