Altium Designer includes the capability to import CircuitMaker 2000 files through the Import Wizard. The Wizard is a quick and simple way to convert CircuitMaker design files to Altium Designer files. The Wizard walks you through the import process and handles both the schematic and library files.
The CircuitMaker 2000 schematic and library file importer is available through Altium Designer's Import Wizard (File Import Wizard) by selecting the CircuitMaker 2000 Schematics and Libraries Files option on the Wizard's Select Type of Files to Import page.
Use the Browse folder icons to set the desired paths for CircuitMaker 2000 Standard Devices Path (DEVICE.LIB file), CircuitMaker 2000 User Library Path (USER.LIB file), and CircuitMaker 2000 Models Path (MODELS directory).
Circuit Maker 2000 is basically a tool for people who are related to electronics and electrical engineering. It is now simple and very easy to use the built-in electric tools and diodes to just combine them on a software and let them see if they work. It has almost every known element in the field of electronics and has the best features and suggestions to improve your circuit board.
If you have any problem or any ambiguity about the software you can send mail to their help desk any time. Also the interface is very simple and reliable, it has a drag and drop functionality of electronic items. You can see on the left side of the tool box, there are symbols of these items. The most popular and the one I know are the Diodes and resistors. If your circuit is not working then the connection will not be established and will be seen as a red blink. So, it is now the best platform to work on rather than bread boards in Electric Laboratories.
Alternative 1: TINA-TI
If your priorities allow, please consider TINA-TI, our free simulator available at: -ti
The OPA656 is in the internal TINA-TI Spice Macro libraries and can be placed in a schematic with a drag-and-drop from the library menus.
Many TI analog components have TINA macros published on their product folders at ti.com, was well as reference circuits that can be downloaded or opened directly by TINA-TI from their URLs.
Alternative 2: Modified OPA656 model
The errors you showed in your message are parameters associated with the macro's JFET model.
We validate our models in Pspice and TINA-TI, so I checked the models description in the Pspice documentation.
The parameters ALPHA and VK are the JFET ionization coefficient and ionization knee voltage.
The BETATCE and VTOTC are the temp coefficients for beta and the VTO respectively.
As an experiment, the results of some Pspice AC & noise sims were compared with the the model as it is published, and with the four JFET parameters commented out. The test circuit was the published reference circuit with a gain of +2.
The results with the four JET parameters removed give a BW that is 15% higher, and noise that is 5% lower than the nominal model.
I do not know if the variations are acceptable for your application, but I have attached a modified model netlist to this thread.
It has the four parameters commented out. PLease try the model in your silumlator and let me know if you still see the errors.
The differences in simulator and model behavior can occur because of syntax, computational and convergence algorithms, and a host of other issues.
Unfortunately we do not have access to Circuitmaker, so we cannot do a more thorough evalutaion of our model in that simulator.
I have a few questions about your circuit:
1. Both power supplies have a terminal named "V+". Should +5V and -5V perhaps have different terminal names?
2. Can you check the current drain of the macromodel?
The model may not have power and the output waveform may be from the R1/R2 signal path from the source to the output node.
Another way to test this is to put a 2k load resistor on the output. If the output swing drops by half, the model is probably not powered up.
The modified model with your circuit copied into in Pspice (+5V/-5V supplies) has 11mA of current drain.
3. The OPA656 is a 5-pin model and it looks like the output node has a pin number of '6'. Can you check to see if the model pins are configured correctly?

Is it possible to list the values of the internal XOPA656 subcircuit nodes V+ and V- ?
If they are +5V and -5V then something else is wrong. If they are not +5V and -5V then there may be some problems with the way Circuitmaker is assigning pins when the model is imported.
With that in mind, I downloaded a Circuitmaker 2000 manual and compared the specified BJT & JFET models to the .MODEL statements in the OPA656 macromodel.
The only difference I could find was the JFET parameters that caused the original problem. Otherwise the BJT and JFET models in the OPA656 acro seem to be compatible with Circuitmaker 2000.
We now add a voltage source to our circuit: Source > Linear > VSource. Note that you can specify values and hot keys in this window. Checking the return box will cause this part selection window to automatically re-open after you've placed the part on the canvas.
To connet our circuit, use the wire tool to connect the pins. We also must add a ground (Source > Linear > Ground in device selection window), so CircuitMaker will know what to use as a reference when calculating voltages. Hook up the circuit like this:
Exit the Analyses Setup window, and click the run button in the toolbar (or press F10). The run button will turn into the stop button with a stop sign icon. (Note that while the simulation is running, you will not be able to access many settings or edit the circuit. Stop the simulation to make the changes.)
Select the probe tool , click on the multimeter window, and click on one of the wires in the circuit to view the voltage of the wire. If you click on a component's pin, you can view the current flowing into the pin, and if you click on a component, you can view the power dissipated by the component.
To do this, right-click on the capacitor and select Edit Pin Data. This menu displays the pin names and their corresponding pin number designations. Check the Show Designations box to disply the pin numbers on the circuit (do not use Show Pin Names, the names often overlap each other and cause confusion).
You should now have four windows open: the circuit, the multimeter, the oscilloscope, and the Bode plot. If they are not open, go to Window in the menu bar and open them. Select the Bode plot window. Take the probe, and click the input of the filter. Hold down shift, and click the output of the filter. Select the oscilloscope window and do the same thing. The oscilloscope should display the input and output waveforms for the frequency you set the signal generator in your circuit to use, and plot the magnitude verses time. The Bode plot will ignore the signal generator settings and use the frequencies you set in analysis setup and use an amplitude of 1, and plot the amplitude versus frequency. Note that the x-axis of the Bode plot is plotted on a logarithmic scale. Use the cursors to find the values of the plot at different points.
My first Arduino project (using an ATMega 328) is triggered by a roughly 5V to 0V edge and works fine overall. (It sends a series of servo arm movements.) But I'm still playing with various simple front end circuits to deliver that edge.
I'd like to use the simulation facility (of either LT Spice or my ancient CircuitMaker 2000) to experiment with these. What would be the simplest way to represent one of the digital input pins please? (Both with and without built-in PULL-UP specified in the program.)
Am I right that your top diagram means that, taking for example the circuit I showed this morning, for rough simulation I just need two diodes, one to ground and the other to 5V, plus a small cap of a few pF? Presumably when I use the built in PULL-UP I would also add a 30k resistor to 5V?
Typical simulations in Spice only explore basic circuit operation, because the component models are approximations. To gain confidence in the edge cases, it is better to test actual hardware because the components are complete, and also respond in a real world way to external stimuli, such as EMI and temperature changes, and to changes in other components. Here you are, asking for a component model. You seem content with a very simplified version, indeed it may be the best you can do without input from the manufacturer. If the simulation fails, you have something definite to work with, But a successful simulation means less because of all the factors it may have omitted. I've used Spice for analog circuit testing, but it was just a preliminary stage to building a prototype. With digital, I don't bother because I know the components and design patterns very well and it almost always works the first time (once the stupid mistakes like backwards diodes etc. have been corrected). Your circuit is a kind of analog/digital hybrid so I see why you want to simulate it. Just take the results with a grain of salt.
