JTAG Test Platform (Boundary Scan Test Platform)

The platform contains Test & Repair, PLD Configuration/Programming and Flash Programming modules.

This platform uses JTAG plug/header of your card, so no extra interface is needed. The platform can detect manufacturing issues, and can be used as a debug tool. PLD Configuration/Programming module supports multi vendors' devices. Flash Programming module runs without simulators/emulators. You could select Flash devices without sockets since we can program Flash in-circuit (on board) directly. It's easier to use , because none CPU register initialization needed. It's also suitable for mass production.

Test & Repair

The platform supports both automatic tests and manual tests. Tests marked with '*' could be run in batch mode with 'One-Click', or, run background without any interactive operation.

Single Device Test *

This automatic operation can detect short between pins (in fact, not only pins of JTAG chip, but also pins of other devices connected to JTAG chip), or short between I/O pins and power supply or ground.

Inter-device Test *

The system reads schematic netlists, and analyzes the device inter-connection, then generates test patterns. Inter-device test can automatically find short (pin to pin, pin to power supply or ground), open and other issues.

Peripheral Test *

The software could test components connected to JTAG device, such as checking ID of a Flash, testing data bus and address bus of SRAM for open-circuit or short-circuit issues, etc.

Manual Test

The system can display status of JTAG chip's pins (something like an oscilloscope or logic analyzer), and can control the chip to output a user defined waveform (something like a signal generator). You can find issues in welding (open, short, etc.) or PCB production by analyzing the phenomenon. Also, it can be used as debugging tool.

PLD Configuration/Programming

One system to configure PLDs of many vendors.

Currently .svf and .vme files are supported.

Our software platform could configure Altera FPGA under Passive Serial mode with .rbf file, and also support configuring Xilinx FPGA under Slave Serial mode with .bit file. Note: Serial configuration mode is NOT JTAG mode.

JTAG Flash Programmer

Features

• Don't need the Flash sockets anymore;
• No need to use debuggers or emulators;
• Lightweight green software;
• CPU architecture independent. Supports CPUs based on x86/PowerPC/ARM/MIPS architectures, also supports DSP, NP, CPLD/FPGA and other SoC;
• Support multi devices in JTAG chain;
• Use CPU standard JTAG port, without extra design;
• NO one-line boot code needed. Run without any configuration for clock, SDRAM, etc.;
• Can read Flash data even CPU hangs or Flash data is corrupt;
• 10x times faster than parallel cable when programming with WH-USB-JTAG cable; 5x times faster as WH-USB-JTAG with WH-USB-HiJTAG;

Functions

• Support many vendors' Flash: numonyx, Spansion, Intel, AMD, ST, SST, EON, MXIC, etc.;
• Read, Programming Flash;
• Block operation (erase, lock ,unlock);
• Besides programming, the software can lighten LEDs to verify the JTAG function;
• Read/Write other ICs;
The JTAG software can read and write other ICs (e.g., CPLD, ASIC, etc.) connected to the JTAG device (usually the CPU, but other ICs are also OK), so you can debug your card without software running. It will highly enhance the debug efficiency and shorten the time to market.
• Easily integrated with manufacturing automation system: Run specified operations automatically and silently without clicking any button.
• Calculating hash value of programming file based on multiple algorithms. Avoid writing wrong file by comparing calculated value with expected value.
• Support batch programming: Automatically program different file to different address;
• Optimized for whole-chip programming;

EthCfg: MDIO Master Debug Solution

With a USB cable, you could read/write the MDIO registers of Ethernet PHY on your computer. Support batch reading.

Schematic (Netlist) Compare Software

Schematic and PCB files are binary files, so they cannot be compared directly. Our software compares them with netlists, which have all info of the design.

The software not only compares connections, but also compares component packages (PCB footprints).

From the comparison result, you can easily see what difference between the schematics or PCBs.

Besides, this utility could be used to validate schematic / PCB file version when archiving.

Other Files Comparing

• BOM File Comparing
• PLD Constraints File Comparing
Supports Xilinx ucf, Lattice prp/lci/lpf and Altera qsf format files.
• Location of Components of PCB Comparing

PLD Pin Location Constraint File Auto Generating Software

PLDs (CPLD, FPGA, and so on) are widely used now. Pin location is a very important design constraint in PLD design.

To generate the pin location constraint, the engineers have to fill the location in the PLD EDA software one by one--manually watch the schematic design in schematic EDA software window, and then switch to the EDA software window to input them, and then switch back to schematic software window to see next pin location. It's boring. And, it's NOT reliable.

Our software reads pin info from schematic netlist file, then generates PLD pin location constraint file automatically.

• Support Xilinx ucf, Lattice prp/lci/lpf and Altera qsf format files.
• Can sort the constraint file by pin location, or by netlist name.
• Filter non-I/O pins with post processing.
