چکیده
Lattice is the leading supplier of In-System Programmable (ISPTM) devices and devices that are fully compliant with the IEEE-1149.1 testability standard. The Lattice product offering includes many devices that incorporate in-system programmability through an 1149.1 compliant test access port (TAP). The ispLSI ® 1000EA, 2000VE, 2000VL, 5000V, 8000/V, ispMACHTM 4A, 4000B/C, 5000VG, MACH ® 4 and 5, ispGDXV and ispGDX ® device families implement 1149.1 testability and are fully compliant with the 1149.1 standard. The ispLSI 2000E, 2000V, ispGAL ® 22LV10, MACH 1SP, 2SP and ispPAC ® device families offer in-system programmability, but do not include 1149.1 boundary scan registers and are therefore considered 1149.1 compatible rather than compliant.

Using Boundary Scan to Link Design and Manufacturing Test
Executive Summary In recent years, many in the electronic test industry have begun to realize that the value of boundary-scan test technology can be leveraged across the various phases in a product's life cycle. In particular, boundary-scan can provide a link between design test with manufacturing test, producing long-term benefits in terms of greater efficiencies and higher quality products. S...
متن کاملAn Embedded Boundary Scan Test System
This paper describes an application of boundary scan IEEE Std. 1149.1 at system level. It provides the description of the design and the implementation options of a VME boundary scan controller board prototype and the corresponding software. The prototype was designed to use the Module Test and Maintenance (MTM) bus, existing in the VME 64x backplane, to apply the IEEE 1149.1 test vectors to a ...
متن کاملAugmented Lagrangian method for solving absolute value equation and its application in two-point boundary value problems
One of the most important topic that consider in recent years by researcher is absolute value equation (AVE). The absolute value equation seems to be a useful tool in optimization since it subsumes the linear complementarity problem and thus also linear programming and convex quadratic programming. This paper introduce a new method for solving absolute value equation. To do this, we transform a...
متن کاملDRAFT: A Scanning Test Methodology for Dynamic and Partially Reconfigurable FPGAs
A new class of FPGAs that enable partial and dynamic reconfiguration without disturbing system operation, raised a new test challenge: how to assure a continuously fault free operation, independently of the circuit present after many reconfiguration processes. A new on-line test method for those FPGAs is proposed, based on a scanning methodology and in the reuse of the IEEE 1149.1 Boundary Scan...
متن کاملInevitable Use of TAP Domains in SOCs
The 1149.1 TAP controller has proven to be an effective test interface for ICs on boards using its standard 4 pin interface (TCK, TMS, TDI, TDO). One of the most important features of the TAP is its Protocol, which provides an easy to follow Plug & Play IC test interface. This Protocol defines and enforces; (1) a Test Reset Mode, (2) a Run/Test Idle Mode, (3) an Instruction Scan Mode, and (4) a...
