# **Analog Circuit Simulations**

For this course, we recommend the use of **[Eldo](http://www.mentor.com/products/ic_nanometer_design/analog-mixed-signal-verification/eldo/)** simulator from Mentor Graphics. You are welcome to use other simulators that may be available to you (e.g. LTSpice, Spectre or Hspice). Some of these also have a schematic-based entry for circuits and simulations. However, it will not be possible for us to support multiple simulators. You will be on your own if you choose to use a different one.
You can find more information about installing and using Eldo [here](http://www.ee.iitm.ac.in/~nagendra/cadinfo.html#cktsimulator).
More information about freeware circuit simulators is available [here](http://www.ee.iitm.ac.in/~nagendra/cadinfo.html#freeware).\
