I thought that one of the other analog chip makers had a spice too but I can't remember who:( I have been to a few talks on simulation given by physicists and EEs who have done chip design. One major drawback that I have found is that the waveform viewer does not provide a logarithmic view and there's no way to get data out of it. It uses either gnucap or ngspice for the simulations, so they're pretty good. The schematic capture is much easier to use and prettier than the other programs. The libraries are quick and easy to use and find parts from. They are very sufficient except my professor requires the '.out' file generated by pspice, so I still have to use that. They are each a collection of programs that work well together (like Orcad) they include a schematic capture, a simulator, a waveform viewer, and a PCB layout tool.
Macspice source for mac#
Macspice 3f5 Is A Complex Circuit Simulator For Mac Free There are a couple of heavy-duty packages and a lightweight program for Linux. You can setup oscilloscope views on any connection too. In Early September 2014 I edited this question and attached a transfer curve for the desired current-limiting diode and later a simplified version of the circuit I am using to model the biological. (voltage is shown in green/red, simply amazing) If you start with one of the gate, (choose it from the Circuits menu), then you can click on gates or digital signals to switch them on/off, and see your circuit react. You can build entire circuits using this and simulate it visually to understand how the circuit works. (you need the ) Edit components and connections by right-clicking anywhere/on a component.
Macspice source software#
You can play with the software by visiting the link, and wait for the applet to pop-up. I found an excellent online written in Java, and its free-and-open-source. Most manufacturers do not want to reveal too many details about their process. LTspice is distributed with models of the Linear Tech parts. Re-distribution of the models is usually a copyright violation. Also most of the free simulators are not distributed with models. Simulating the entire design is not usually practical. You should only simulate subsections of your design.
You will not be able to avoid a prototype. Unless you are doing work for an IC manufacturer the manufacturer will not give you detailed models. Except for simple circuits you will spend most of your time getting models and determining where the models need to be modified for your application. Each of the talks seems to end like this.
