Drivers for the Altera USB-Blaster and the FTDI FT245 have been tested by the developer.
#Altera usb blaster cyclone iv driver serial
The adv_dbg_if core, all of the JTAG cores, the JTAG serial port, and the adv_jtag_bridge software program have all been tested and shown to work in both ModelSim simulation and in FPGA hardware (Altera Cyclone II, Xilinx Spartan 3, Xilinx Virtex4). Modular hardware design allows new busses and processors to be supported. Modular software design allows new JTAG cables to be easily added. This allows legacy hardware systems to be debugged using GDB 6.8 via RSP. Uses less hardware than older "dbg_interface" core: 48% less logic, 28% fewer registers under Altera Quartus v7.0.Īdvanced JTAG Bridge program uses RSP to communicate with GDB, making it compatible with GDB 6.8.Īdvanced JTAG Bridge program can be compiled to support the legacy debug hardware unit (dbg_interface). Even complex systems can be debugged using only two command-line parameters. JTAG chain auto-enumeration and BSDL parsing keeps command-line options to a minimum when running the adv_jtag_bridge program. All components used in the debug system are bundled together. No more guessing which version of the debug unit works with which JTAG core or GDB interface program. Includes overview document explaining the complete debug system, component selection, and component interconnections. Communication can be done via the filesystem, or via network sockets if VPI is supported by the simulator. Programs can now be downloaded and executed on simulated hardware (in ModelSim, Icarus, etc.). Includes support for simulator connection. This allows users to get logging from their programs without the need for a dedicated, external RS-232 link. Includes a "JTAG serial port," a device which looks like a UART on the SoC WishBone bus, but which transfers data via JTAG to the jtag bridge program, where it can be viewed via telnet.

Includes full support for OR1200 hardware watchpoints/breakpoints and counters, including a GUI client program "AdvancedWatchpointControl" This is the Actel equivalent of the Altera sld_virtual_jtag or the Xilinx BSCAN TAP, it allows a user to connect to the advanced debug unit through the main FPGA JTAG connection.Ĭables supported: Altera USB-Blaster, Xilinx Platform Cable USB (DLC9 and DLC10), various FT2232-based cables, various FT245-based cables, Xilinx Parallel Cable III (IV in compatibility mode), Altera ByteBlaster II, XESS parallel interface This is the Xilinx equivalent of the Altera sld_virtual_jtag interface, it allows a user to connect to the advanced debug unit through the main FPGA JTAG connection. Supports Xilinx BSCAN_* virtual JTAG interface. This allows the user to connect to the advanced debug unit via the same JTAG port which is used to program the FPGA, similar to the way the Altera Nios II processor debugger works. Supports Altera sld_virtual_jtag interface. This configuration is often found on Xilinx reference hardware, and was not supported by previous debug hardware. Documents describing each component individually are included (under doc/ in each component's subdirectory) as secondary material.

This suite includes a top-level document explaining the workings of the debug system and each of its components, including information to help the user choose the best components for his or her target system, and information on how to connect them. The fourth important component of the system is the documentation. Communication is performed via a JTAG cable, which adv_jtag_bridge drives. This component acts as a communication bridge between a source-level debugger program (GDB, not included in this package) and the JTAG TAP. The third component is a software program called "adv_jtag_bridge," which is designed to run on the user's workstation. Four different versions of the JTAG TAP core are included, targeting four different types of system. The second component is a JTAG TAP this relatively small hardware core acts as a connection between the adv_dbg_if core and the external pins of the target chip (ASIC or FPGA).
The first component, the "adv_dbg_if" core, is a hardware core designed to interface directly to the OR1200 CPU and a WishBone bus, controlling the CPU and reading and writing data to both the CPU registers and memory addresses on the bus. In particular, target systems using the OpenRISC 1200 processor and a WishBone bus are currently supported by the Advanced Debug Interface.

The Advanced Debug Interface is a suite of IP cores and software programs designed to allow a developer to download code to a target CPU in a System-on-Chip, then perform source-level debugging of that code.
