Embedded Logic Analyzer to Observe Low-Level Signals
The Arm CoreSight ELA-500 provides an effective way to observe low-level signals, by offering a way to zoom into the root cause of data corruption. You can program the ELA-500 to trigger signal capture in response to a particular event, in addition to causing triggers elsewhere in the SoC to further help with the debug process.
Features and Benefits
The ELA-500 addresses many of the Design For Test (DFT) methodology requirements, by making products inherently debuggable at all stages of their lifecycle.
Multiple ELAs can be instantiated in a SoC to monitor system signals, each tightly coupled with associated IP, such as a processor or a Cache Coherent Interconnect (CCI). You can create a cross-trigger network alongside these ELAs to send and receive trigger signals, and expanding visibility to the whole SoC.
ELA trigger outputs can be used to control clock-gating for a scan dump of registers values.
