Boundary-Scan Test (BST) technology has been widely used. To further extend the application of BST, a BST system based on network interface card is designed and implemented. In this paper, the theorem of boundary scan test is briefly introduced. The methods of designing the BST controller including hardware and software are presented. On the basis of Client/Server model, BST controller played as a server role while circuit under test(CUT) as a client. By using the designed controller and DEMO board which contains two BS chains, the remote boundary-scan test system has been established. Test results indicate that the system can correctly identify fault styles and exactly locate the fault pins.
