List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
Spring loaded pins are a component of the bed of nails tester. A bed of nails tester is a traditional electronic test fixture used for in-circuit testing.It has pins inserted into holes in an epoxy phenolic glass cloth laminated sheet (G-10) which are aligned using tooling pins to make contact with test points on a printed circuit board and are also connected to a measuring unit by wires.
Software which is used to run reproducible tests systematically on a piece of software under test is known as a test harness; part of its job is to set up suitable test fixtures. In generic xUnit , a test fixture is all the things that must be in place in order to run a test and expect a particular outcome.
Side view of a PCB showing a solder bead and test probe. Bead probe technology is a probing method used to connect electronic test equipment to the device under test (DUT) within a bed of nails fixture. The technique was first used in the 1990s [3] and originally given the name “Waygood Bump” after one of the main proponents, Rex Waygood.
Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit (IC).Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit.
Flying probes were introduced in the late 1980’s and can be found in many manufacturing and assembly operations, most often in manufacturing of electronic printed circuit boards. A flying probe tester uses one or more test probes to make contact with the circuit board under test; the probes are moved from place to place on the circuit board ...
TINA software is available in installable and cloud-based versions. Feature versions exist for use in industry [6] and for educational use. [2] [7] TINA allows simulation, design, and real-time testing of hardware description language (HDL), such as VHDL, VHDL-AMS, Verilog, Verilog-A, Verilog-AMS, SystemVerilog and SystemC and for microcontroller (MCU) circuits, [2] as well as mixed electronic ...
