5.4 Boundary scan and IEEE standard 1149.1. Boundary scan is primarily concerned with delivering test signals to and collecting response signals from the I/Os of several integrated circuits which have been assembled into a complete working system, rather than the testing of an individual unconnected IC. The IEEE 1149.1 Boundary Scan Test standard , also known as Joint Test Action Group (JTAG) Standard, has been widely accepted and practiced in the testing community, and provides excellent testing features with low complexity. However, it was not intended to address at-speed testing of crosstalk faults. Therefore, we extended the IEEE 1149.1 boundary scan architecture to at-speed test …

JTAG vs. IJTAG Electronic Design. The IEEE Standard 1532 is a formal extension to the IEEE Standard 1149.1 (also known as JTAG) for PLDs. This standard defines the three items required to configure in-system programmable logic devices. The three essential items are: • Device architectural components for configuration • Algorithm description framework • Configuration data file Figure 1 illustrates configuration-specific, grammed through the JTAG interface. However, the C8051F2xx family of devices does not support the IEEE 1149.1 boundary scan function. The information required to perform FLASH pro-gramming through the JTAG interface can be divided into three categories: 1. JTAG interface information: a.
