Xilinx applies Agilent tools to LTE verification

Agilent Technologies has announced that Xilinx has employed Agilent EEsof SystemVue software plus Agilent test equipment, including the Agilent N5106A PXB baseband generator and channel emulator, to verify 3GPP LTE hardware blocks using precisely configured test vectors from a credible algorithmic reference.
The Xilinx wireless engineering team needed to develop production-quality LTE uplink LogiCORE IP for Xilinx eNodeB customers. Xilinx had to verify all LTE algorithms and hardware IP cores against published standards, but the company’s engineers found that existing test-vector creation methods either lacked the fine parameterization and flexibility needed to test individual LTE PHY algorithms and blocks, or they lagged behind updates to the standard.
Bill Wilkie, wireless and signal processing director (Europe) at Xilinx, commented on the solution: “We used Agilent’s SystemVue LTE baseband verification library to validate Xilinx’s LTE reference IP against the latest version of the LTE standard. When combined with Agilent’s N5106A, SystemVue not only saved us weeks of validation time, but also it gave us confidence that our LTE Layer 1 reference design was 'production ready’ for our customers. SystemVue clearly added value to our traditional Layer 1 design and verification process.”
Xilinx used Agilent SystemVue and the W1910 LTE baseband verification library to create highly specific LTE test vectors, which were downloaded to the Agilent N5106A PXB baseband generator and channel emulator, which added fading and control to the real-time test environment. A hardware digital interface supported the Xilinx Virtex-6 FPGAs.
Key features of SystemVue that Xilinx employed in this project include direct links to the Agilent N5106A and 89601A vector signal analyzer software, the W1910 LTE PHY reference library that interoperates with the measurement equipment, and a simple polymorphic modeling interface.
