In-circuit emulation (ICE) is the use of a hardware device or in-circuit emulator used to debug the software of an embedded system.It operates by using a processor with the additional ability to support debugging operations, as well as to carry out the main function of the system.
Background debug mode (BDM) interface is an electronic interface that allows debugging of embedded systems. Specifically, it provides in-circuit debugging functionality in microcontrollers. It requires a single wire and specialized electronics in the system being debugged.
The goal is normally debugging and functional verification of the system being designed. Often an emulator is fast enough to be plugged into a working target system in place of a yet-to-be-built chip, so the whole system can be debugged with live data. This is a specific case of in-circuit emulation.

debugWIRE is supported by all modern hardware debuggers from Microchip.This includes Atmel-ICE, [3] JTAGICE3, AVR Dragon, JTAGICE mkII, and SNAP. [4] It is also possible to build a cheap debugWIRE hardware debugger [5] based on an open-source Arduino sketch, [6] using a general USB-Serial adaptor or ATtiny85 board, [7] or a CH552 microcontroller.
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.
