B2 Spice A/D Lite4.2.14

This is the light and free edition of B2 Spice A/D, a feature-rich software application that can be used by technicians, engineers and students similar electrical circuits. It is packed in a professional-looking interface that sports numerous options and configuration parameters.

Extensive list of devices

As far as devices are concerned, you can draw the ground, current and voltage source, ammeters and voltmeters (horizontal or vertical), voltage probe, network analyzer, capacitors, inductors, mutual inductor, simple or temperature dependent resistor, controlled sources, bipolar transistors, and so on. It is possible to choose a part by name or to browse for one in the device list.

Numerous digital parts and categories

Several types of digital parts may be applied in the project, such as probe, input source, combiner, splitter, ground, buffer, inverter, comparator, gates, flip flops, encoders, decoders, counters, and registers. Additional devices include continuous or discreet time transfer function, current controlled switch, inductor coupling, lossy or lossless transmission lines, non-linear dependent current or voltage source, piecewise linear, voltage controlled switch, transformer, and so on.There are plenty of categories that you can choose from, like analog instruments, meters, multiplexers and multiplier, buffer, comparator, crystal, diode, line driver, mixed mode, rectifier, reference, sources, switches, timer, transformer, and transistor.Objects can be arranged in any way in the document layout and their properties can be easily edited. You can a simulation with one click to study the circuit log, load test vector files, edit external libraries, check for wiring errors, and much more.

Evaluation and conclusion

The tool uses a surprisingly low amount of CPU and RAM. It has a good response time and executes commands rapidly, without causing the operating system to hang, crash or pop up error messages. All in all, B2 Spice A/D proves to be a resourceful program for simulating electrical circuits.
