Chapter 10. Jtag Boundary-Scan Testing For Cyclone Iv Devices - Altera Cyclone IV Device Handbook

December 2013
CYIV-51010-1.3
CYIV-51010-1.3
This chapter describes the boundary-scan test (BST) features that are supported in
Cyclone
this chapter.
Cyclone IV devices (Cyclone IV E devices and Cyclone IV GX devices) support IEEE
Std. 1149.1. Cyclone IV GX devices also support IEEE Std. 1149.6. The IEEE Std. 1149.6
(AC JTAG) is only supported on the high-speed serial interface (HSSI) transceivers in
Cyclone IV GX devices. The purpose of IEEE Std. 1149.6 is to enable board-level
connectivity checking between transmitters and receivers that are AC coupled.
This chapter includes the following sections:
■ "IEEE Std. 1149.6 Boundary-Scan Register" on page 10–2
■ "BST Operation Control" on page 10–3
■ "I/O Voltage Support in a JTAG Chain" on page 10–5
■ "Boundary-Scan Description Language Support" on page 10–6
