Moreover, to be able to scale up the lab is very difficult due to the high cost of these flashing/debugging devices and the lack of chips in the industry, which makes testing equipment delayed and cannot be produced in time. Flashing and debugging devices are used by many labs and it requires someone to assist in manual setup. A simple setup job consumes a lot of effort to move from office to lab as well as waiting time for equipment. With the need to reduce investment costs for these devices by sharing them in many labs as well as reducing the effort of test engineers for a simple setup job that repeats continuously, we decided to develop a “switch- in network device”.
Basically, this device is developed based on a controlled electronic circuit with an intranet and web booking capabilities. Along with that, this device also aims to become a part of the continuous automation testing system called Jenkins. 9 CHAPTER 1: INTRODUCTION Chapter Outline 1. Motivation For The Research 1.

Circuit switching method 10 1. MOTIVATION FOR THE RESEARCH As mentioned above, our lab system is now becoming overloaded with a shortage of flashing equipment for labs. Moreover, the setup of these devices is very simple, but it takes a lot of time for testing engineers to disassemble manually. In addition, these devices do not have a clear management system for usage time.
When someone has a need to use them, they have to contact each person in the team to know which lab the device is connected to and whether it is being used or not. That is the reason why we develop a switch-in network device. Price for each setup of IC5000 devices for lab could be take over €3000. So that if we prepare for each lab 1 IC5000 it will cost overall €12000.
The same as IC5000 for each XCP setup it will cost for device and license €1800 and for the whole lab in the rack is €7200. Full cost for debugger device in test lab is €19200. It could be a huge amount for test lab setup. These devices is require for testing lab but we don’t need to plug it all the time for lab it can be use in sharing mode.
With sharing mode, it could save €14400.
