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

Flexible Debugging

The ELA-500 addresses many of the Design For Test (DFT) methodology requirements, by making products inherently debuggable at all stages of their lifecycle. 

In-Depth System Signal Monitoring

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. 

Scan Dump Register Values

ELA trigger outputs can be used to control clock-gating for a scan dump of registers values.
