Get JTAG Boundary Scan Architecture Tools to Runs Your Electronics Efficiently

With so many electronic equipment here and there around us, you need to have some tools to test these connections as they have become part and parcel of our lives. Considering this factor in mind, IEEE standardized a testing specification known as JTAG (Joint Test Action Group) in 1990. It is used for testing connections on printed circuit boards which are implemented at the integrated circuit (IC) level. Since, it is not easy to test complex circuits with traditional testers; JTAG becomes the perfect solution to overcome problems with physical testers. JTAG uses the software programming functions to track the fault coverage in the electronic devices by making these devices run through a micro-controller or any other programmable device.

Since JTAG is an electronic tester, it eliminates the need to use physical testers to test the integrated circuits on a board but in order to do so; the devices need to be JTAG enabled. This can be achieved by preparing JTAG boundary scan architecture for the integrated circuits. An additional cell called the boundary scan cell is developed for each pin on the board which can set or read data on each pin. Boundary scan cells are connected together and the data is serially shifted into these cells. This process is controlled from a serial data path known as scan path or scan chain which defines the principle of the JTAG interface and how it works.

One of the software program used as boundary scan tool is onTAP Series 4000 which is prominently used for JTAG testing. It does not require expensive hardware to run but only the TAP CONNECT JTAG Controller which is easy to afford. It is a dual-channel and high speed USB programming controller that allows multiple chain testing to run tests and program memory devices. Also, you need to install BSDL (Boundary Scan Description Language) files for the devices to run onTAP Series 4000 which are created by the manufactures so that the JTAG complaint devices can map with each other.  

So, if you are looking to test the electronic circuits at your place, you can get JTAG boundary scan architecture tools over the internet as many of the vendors are providing JTAG boundary scan architecture online. These companies will provide you all the information and support through their websites which you need to run tests on the electronic boards so that you can streamline their operations and run them smoothly.
