It's very restrictive. They not only insist on on beeing a student,
they also want the name of your teacher.

They also specifically disallow schools to deploy it, e.g., network wide!

With their current restrictions, I can't see anyone who *knows* about,
e.g.,
LTSpice, actually using their product.


Hi Joel,

LTSpice is pretty good for analog simulation, but CircuitLogix
provides both analog and digital simulation.

Hello Carl,

First of all LTspice has also built-in mixed mode capability.

I tried now the CircuitLogix simulator. I have to admit that this
animation capability of CircuitLogix is a good feature especially
for education. www.CircuitLogix.com

On the other hand I couldn't run any of the benchmark SPICE-circuits
with the CircuitLogix program. It always gives the error message:
Invalid CIRCUIT path/file name.
I tried some examples, e.g. File->Open ".cir" sqrt.cir
http://www.intusoft.com/models/MCNC.zip
(I remaned the SPICE netlist sqrt.sp to sqrt.cir)
Maybe you can tell me what I should change to run this example
with the CircuitLogix simulator.

Overall LTspice is a much more compatible SPICE simulator.
Many of the commercial SPICE simulators don't have this compatilibity.
You can take every SPICE book and immediately run the examples
with LTspice on a netlist level.
I also like the more powerful waveform editor in LTspice.
It can easily work with data files having 1Giga-Byte.
I reommend LTSpice for people who want SPICE.
Not to forgot the many SMPS-models provided with LTspice.

CircuitLogix will have it's place in education because of it's animation
capability. I appreciate that it's free for students and not limited
as most other student versions of commercial SPICE-simulators.
Isn't it the refreshed CircuitMaker program?

Best regards,
Helmut

Hello Helmut,

As much as I would love to comment on CircuitLogix and its Netlist
capabilities, I am not going to bother. The rude comments that are
posted here and accusations regarding being a shill are completely
discouraging and counterproductive to having any useful discussion
regarding circuit simulation. It seems that certain people in this
discussion group are more interested in bullying than exchanging
information.

Please note that I am not including you, Helmut, among this group of
small-minded individuals, but it is clear that some people who
subscribe to this user group have an agenda regarding what types of
information they would like to discuss and they are unwilling to allow
any other perspectives to enter the discussion.

Thanks Helmut,

Changing TRTOL to 7 did get rid of the speed difference at least on
the SQRT circuit. LTSpice ran it at 101s. Didn't try CShunt. Micro-
Cap has CShunt available but not PSpice (at least our version) so
wouldn't have a good test across the three simulators. I'm going to
guess that TRTOL is the factor for the others also, since we've put a
little too much time into testing these. Time to get back to real
work.
