Spice is a powerful tool for circuit analysis. But it often surprises users with
. holes in its abilities and strange definitions
. lack of industry-wide standards
. the need for the user to model the physics of their circuit, not just draw the schematic

I hope this blog will educate users and promote discussion in these areas.

Welcome


Each post is on a separate page - the list is over here   =====>


I have been both a Spice user and a developer of a Spice program for many years. In doing this, I discovered some important Spice topics that don't seem to have a home anywhere. I'll try to address some of these here. And add more from time to time.

"How to Think Like Spice" talks about the big-picture mindset I use to work effectively with Spice. A good place to start.

If you have a topic suggestion, comment here or send me an email (spam disguised address: blogspot [at] 5spice.com). Keep in mind that simulating integrated circuit designs is a different world from my focus.


Rant
To get the best results using circuit simulation, it is important to remember to use the tools you have. Computer simulation is a software tool that produces exact outputs based on exact inputs (well, most of the time). It can be very useful in circuit design. Circuit design is a creative and analytical process that uses the computer between your ears. If this second computer is not engaged, the results of the first are likely to be worthless.


Note
Some posts talk about adding a specialized Spice element, such as a NodeSet, as a symbol to the schematic. This reflects usage in 5Spice. Your Spice program may add specialized Spice elements without using schematic symbols.


5Spice tutorials are now on YouTube.
