SystemBIST enables multi-design, multi-FPGA configuration and is used as a substitute for using multiple platform Flash or proms for configuration of just a single design. While lowering the FPGA configuration cost, SystemBIST adds the ability to update CPLDs when needed and execute JTAG/IEEE 1149.1 tests at PCB power-up, without a personal computer or ATE. The device does not require any JTAG software to execute or to integrate with the system mission mode software.
The thumb module also contains a 512Mbit Spansion flash device, pass and fail LED indicators, a 40Mhz oscillator and a JTAG interface. The memory supplied on the thumb module is oversized as using SystemBIST's compression and data reuse, a full D size PCB with eight of the largest FPGAs would only require twenty percent of the memory for both FPGA and test data, allowing the remainder of the memory to be shared with processor boot code. The included software enables the user to create configuration and test scenarios and generate reports which indicate the amount of flash memory needed for a new design. Users can import JTAG tests from other boundary-scan tools or use the software to generate new tests. The thumb module is ideal for FPGA designers to show test engineers how to use the embedded JTAG capability as well as having test engineers show FPGA designers the added benefits of using a pre-engineered solution for FPGA configuration that can lower downstream costs in test and in-the-field updates.
"This SystemBIST thumb module is a good way to begin evaluating the importance of coordinating FPGA programming with embedded JTAG test. In a typical test scenario, we're loading multiple FPGA designs all coordinated by the SystemBIST IC" said Carl Nielsen, SystemBIST product manager. "Since it is ready to plug in to most popular JTAG headers on PCBs, test engineers can use it to evaluate the advantages of embedded PCB BIST Built-In-Self-Test on an existing PCB without convincing a designer to design it in first, essentially a BOST Built Off Self-Test approach." "Some customers are already using early SystemBIST thumb module prototypes as low cost JTAG testers because the module can be easily plugged onto a PCB temporarily and doesn't require a Personal Computer and software. If your yields are good, you can test many PCBs, get the 'green pass light' and only in the event of a failure, use the PC to extract the stored failures from the thumb module." Nielsen added, "It is fast compared to PC based JTAG software, since there is no overhead, the test times are short and predictable. The test time is just the number of TCK clocks needed multiplied by the TCK period."
The SystemBIST IC is 13mm x 13mm, the PCB is 4.8cm x 3cm (1 7/8 x 1 1/8"). The thumb module is RoHS compliant and can interface to 0.100" Altera/Actel and 2MM Xilinx style IEEE 1149.1/JTAG interfaces at 3.3V. The PCB is powered by the target UUT and supports continuous TCK rates to 20Mhz. The evaluation kit has a price of $295.00 and includes cables, schematics and software.
