Corelis JTAG tools provided real benefits for Ixia

Tests Double-Data Rate SDRAM memories through Xilinx Virtex FPGAs

Located in Calabasas, California, Ixia is a leading developer of sophisticated optical and electrical network traffic performance analysis solutions. Mr. Xinchen Wang, Hardware Engineer at Ixia, is responsible for JTAG testing and verification for one of Ixia’s new interface load modules.

According to Xinchen Wang, to achieve increased net coverage through JTAG testing for Ixia’s new traffic generation and analysis tool, it is important to first verify that all the FPGA’s external Double Data Rate (DDR) SDRAM connections are properly placed and functioning correctly to aid in further design troubleshooting.

Corelis proposed a ScanPlus solution tailored to meet Ixia’s requirements. Corelis provided a PCI-1149.1 JTAG controller with a pre-verified DDR SDRAM testing software package with some minor updates to generate memory-testing vectors through JTAG compatible Xilinx FPGAs. The generated vectors successfully tested the interconnects between the FPGAs and the connections to the DDR SDRAM; and furthermore, verified the general functionality of the memory device according to its own published specifications.

Xinchen Wang puts it this way, “The Corelis ScanPlus boundary-scan interconnect tester is also a highly effective memory test suite that allowed us to reduce prototype debug time and improve our time-to-market. The Corelis technical support team was extremely helpful and committed to helping IXIA meet its project dead-line.”

“Thanks to Corelis’ ScanPlus system, and the ease with which it integrated with our CAD tools to automatically generate thorough and comprehensive boundary-scan test patterns, the Rapid2 project is now back on schedule.”
