Description: Circuit Simulator 2019 Analogic circuit simulator OP/AC/DC/TRAN/DISTO/NOISE/FFT/FOUR/TF TEMPERATURE SWEEP Dynamic Operating Point * Dynamic TRAN * Dynamic AC **
* Values of Voltage and Current are displayed on the schematic in real-time. For TRAN you had to select the tstart tstop tstep and clicking on the menu Export to (in the Setup Analysis) ... ** You had to select the desired frequency and run the analysis. (For current you had to insert Ammeters) Before simulate circuit...you had to do these steps: autonode and create netlist.
It uses the ngspice simulator
about 105.000 lines of source code
Multimeter with wires Virtual Multimeter Ammeter WattMeter Multimeter on Component THDAnalyzer Bode Plotter (mag phase) Function Generator aka Signal Generator Oscilloscope for AC/TRANSIENT (with and without axis-transformation and x zoom) 2 channels Resistor (two types),VarRes Capacitor,VarCap,PolCap Inductor Battery, Voltage Generator, Current Generator Opa-5 (works only with components with 5pins with the following order of pins: vin+ vin- v+ v- out) with others you can use simply the auto gen n-ping component self-recognition using .subckt of Voltage Micropower Ref Diode (A K) Auto gen n-pin component with .model/subckt assignment from libraries Diode bridge NPN PNP PMOSFET NMOSFET ZENER DIODE, DIODE, NJFET, PJFET TRANSFORMERS, CRYSTALS Diode Led Voltage Controlled Switch Current Controlled Switch TextObj (add description of the circuit) Auto Noding NetList export Wire to 2 wires join by a Junction Sheet Size Sheet Name Copy/Paste/Rotate Component etc
Voltage under the name of the node (green color default) Current near the value of resistors batteries etc (red color default) with also the Colored Arrow Power Loss Calculator Settings of analyses can be saved for the active schematic plus NGSpice Options Customized colors for some instruments Reload of the libraries (.lib) Creation of component (subckt or model) in lib files (custom lib files and auto-reloading of them) Graphes can be saved to image files Dynamic OP Analysis (you can adjust the value of RCL and see how the circuit changes) *Works only with .OP analysis. Dynamic TRAN Analysis Dynamic AC Analysis Plot TRAN feature (on node/on component) TC1 TC2 TEMP TNOM IC parameters are now available (with IC you had to specify uic in .tran) SCH files will be zipped with bzip compression View graphes of analyses with GnuPlot
Requirements: Linux x86_64bit Monitor 21" 512-1024 MB of RAM GnuPlot ngspice
2.36.0.0
-Fixed autosize function (now it calculates the right dimensions of the schematic at every zoom levels)
-Fixed loading options variables when the program starts
-Fixed in the Bode Plotter (magnitude+phase) Page (under Plotter Window) the loading of the curves
-Added the possibility to rename the Names of Nodes (it dos not accept numeric Name)
-Added the possibility to rotate Opa_5 (right or left) with Swap Vin+/Vin- pins function.
-Added the possibility to Swap the middle pin of Custom Components with 3 pins (top or bottom positions of the middle/center pin)
-Fixed the function that retrieves the right Voltage/Current (nodes/components) for the Dynamic .TRAN
-Added Power Text component. It shows the Power Loss (components) and Power Generated (sources) as a summation of these. It works only with DC circuits.
-The About Window now shows also the Build Date of the Current Version.
-Added the function that checks if the Model has been assigned to the components
-Added the possibility to assign Model definitions to the Zener Diodes (some use .MODEL others use .SUBCKT)
-Corrected the popupmenu for the components
-Added the ability to show/hide the Voltage for any individually wires
-Added some analyses messages in the statusbar
-Added the autonodes option as a checkbox. This works in the Dynamic .OP. If not checked Circuit Simulator will simulate the circuit with the names of nodes changed by the user instead of auto-assigning the names to them every time.

Now I am working for the print functions
In the previous releases I have fixed some bugs and I have implemented the export to bmp/jpg/pdf functions.
Coming soon a new version with other corrected bugs. There is a bug in the dynamic tran with nodes labeled with 0.
with this version you can also insert your customized transformers (you had to know a little of ngspice)

My philosophy is this: a program for linux under linux, a program for windows under windows!
