BitPhyer Tools

BitPhyer is a family of hardware platforms used to test the IEEE 802.3™ MAC, Flow Control, PCS and RS layers for Ethernet devices. This platform is based on Xilinx FPGAs and custom built hardware which are used to create a flexible bit-level based test system. BitPhyer can be used to generate arbitrary bit patterns and frames and enables users to define their own test scripts in addition to the UNH-IOL generated test plans included with the system. The BitPhyer family of hardware platforms supports various speeds and duplexes over several port types from 10Mb/s to 10Gb/s.


  • Decrease costs and testing time by implementing a common set of test cases for easy compliance comparison
  • Create automation of UNH-IOL Test Plans
  • Access to industry recognized test practices
  • Ability to add customizable test cases
  • Increase consistency of testing between development teams using the same platform
  • Faster root cause analysis of conformance issues
