To find the trend of one or more desired values in a single graph, you can use the DC sweep analysis feature in SPICE. This simulation of an electronic circuit gradually varies the value of the ...

One simulates up to 50× faster than the other, and both will give you comparable accuracy. Which engine would you choose for your power supply circuit? Sounds like a trick question, but it isn’t.

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...
