O-RAN Radio Unit (O-RU) Chipset Design Testing and Validation Solution Using Pre-Silicon Emulation

 

Introduction

 

Next generation O-RAN Radio Unit (O-RU) Chipset design and validation teams face new and diverse test challenges. Standard based, open fronthaul architectures, and gNB disaggregation are driving the need for flexible peer emulation, and comprehensive analysis, including multi-domain combinations of LTE and 5G signal test scenarios with standard-based O-RAN CUS protocol generation and measurement.

 

Complete O-RAN Radio Unit Chipset Test and Validation

 

Keysight IxVerify 5G O-RAN accelerates O-RAN Radio Units (O-RU) chipsets design and maximizes test coverage before tape-out, through a combination of O-RAN compliant CU-plane stimulus and analysis integrated with 3rd party ASIC emulation platforms.

 

To optimize your design workflow from simulation to prototyping, IxVerify 5G O-RAN is using the same PathWave Signal Generation and Open RAN Studio applications to emulate a Distributed Unit (O-DU), generate test vectors, push the traffic through the ASIC emulator and use PathWave Vector Signal Analysis to perform the 5G and LTE signal measurements necessary to validate an O-RAN chipset design functional operation and performance.

 

 

Keysight IxVerify 5G O-RAN—Solution Overview

 

Designed for LTE and 5G O-RAN Radio Unit (O-RU) PHY chipset and SoC testing and combined with third-party Pre-silicon Emulation solutions (Cadence, Mentor, Synopsys), Keysight’s IxVerify 5G O-RAN provides a powerful ‘wrap around’ environment to validate DUT’s uplink and downlink functional operation, with cross-domain measurements on both O-RAN and Digital IQ interfaces.

 

    • Build O-RAN compliant CU-plane test vectors by using PathWave Signal Generation (Signal Studio Pro) and Open RAN Studio

    • Emulate an O-RAN Distributed Unit (O-DU) by using Open RAN Studio

    • Send the testing stimulus towards the transactor interfaces connected to the emulator holding 5G Radio Unit chip design (Design Under Test—DUT) by using IxVerify 5G O-RAN

   • Capture and accurately timestamp the DUT’s response by using IxVerify 5G O-RAN and Open RAN Studio

   • Perform measurements needed to validate if the O-RU meets standard compliant operation and radio performance by using PathWave 89600 VSA for 5G NR

 

To ensure measurement consistency between both sides of the O-RU chip design, IxVerify 5G O-RAN and Open RAN Studio software leverage the same industry leading 5G signal generation and measurement science that is used in the Keysight spectrum analyzers and signal sources. This tight coupling ensures that the CU-plane messages and baseband information match exactly with the IQ data on the Analog side of the Radio Unit chip design.
