What is JTAG HS2?
The joint test action group (JTAG) HS2 programming cable is a high-speed programming solution for Xilinx® field-programmable gate arrays (FPGAs). The HS2 attaches to target boards using Digilent’s 6-pin, 100-mil spaced programming header or Xilinx’s 2×7, 2mm connector and the included adaptor.
What is a JTAG cable?
The JTAG-USB cable allows you to use your PC to connect to a JTAG scan chain or to access an SPI interface on a board equipped with the appropriate 6-pin header. In this way, you can program devices on Digilent programmable logic boards using the Digilent Adept Suite.
Who uses JTAG?
JTAG has been in widespread use ever since it was included in the Intel 80486 processor in 1990 and codified as IEEE 1491 that same year. Today JTAG is used for debugging, programming and testing on virtually ALL embedded devices. With the invention of integrated circuits came the need to test physical interconnects.
What is the need of JTAG?
JTAG is not JUST a technology for processor debug/emulation. This standard was developed to provide a technology for testing Printed Circuit Board Assemblies (PCBAs) without needing the level of physical access required for bed-of-nails testing or the amount of custom development needed for functional test.
What is JTAG and how does it work?
JTAG is a common hardware interface that provides your computer with a way to communicate directly with the chips on a board. Today JTAG is used for debugging, programming and testing on virtually ALL embedded devices.
What is JTAG debugging?
Today JTAG is used as the primary means of accessing sub-blocks of integrated circuits, making it an essential mechanism for debugging embedded systems which might not have any other debug-capable communications channel. …
How does the jtag-hs2 connect to the target board?
The HS2 attaches to target boards using Digilent’s 6-pin, 100-mil spaced programming header or Xilinx’s 2×7, 2mm connector and the included adaptor. The PC powers the JTAG-HS2 through the USB port and will recognize it as a Digilent programming cable when connected to a PC, even if the cable is not attached to the target board.
What is the JTAG-USB cable used for?
The JTAG-USB cable allows you to use your PC to connect to a JTAG scan chain or to access an SPI interface on a board equipped with the appropriate 6-pin header. In this way, you can program devices on Digilent programmable logic boards using the Digilent Adept Suite.
What is the JTAG HS2 programming cable?
The joint test action group (JTAG) HS2 programming cable is a high-speed programming solution for Xilinx ® field-programmable gate arrays (FPGAs). The cable is fully compatible with all Xilinx tools and can be seamlessly driven from iMPACT™, ChipScope™, and EDK.
How do I program devices on Digilent programmable logic boards?
In this way, you can program devices on Digilent programmable logic boards using the Digilent Adept Suite. You can also program AVR micrcontrollers on Digilent embedded control boards using the Digilent AVR programmer application.
