Testing SOC CPUs, like ARM based processors, on Automatic Test Equipment (ATE) presents unique challenges to engineers as device functionality cannot be confirmed through DFT alone. Production tests require an additional measure to evaluate functionality, typically accomplished by having a firmware engineer develop an ATE specific image. Since developing this firmware is predictably debug intensive, resolving issues on the ATE without tooling support can be a cumbersome undertaking. PortBridge provides the capability to run a high-level debug tools like ARM Development Studio or OpenOCD directly on the DUT using the ATE, reducing debug time and simplifying the bring-up process. Integration with these programs allows firmware engineers the ability to develop directly on the ATE on an industry-standard toolset and eliminates the need for time consuming simulation or emulation. Additionally, to allow collaboration across geographically distributed teams, PortBridge provides the ability to remotely connect to and debug the DUT.
