SmartDebug
SmartDebug is a new debug tool added in Libero SoC v11.0 software that supports probe capabilities in
the SmartFusion2 architecture and also supports device debug features for memory. SmartFusion2
devices have built-in probe points that greatly enhance the ability to debug logic elements within the
device. The enhanced debug features implemented in SmartFusion2 devices give access to any logic
element and enable designers to check the state of inputs and outputs in real time. Live Probe and Active
Probe are only available on the SmartFusion2 family of products.
• With Live Probe, two dedicated probes can be configured to observe a Probe Point which is any
input or output of a logic element. The probe data can then be sent to an oscilloscope or even
redirected back to the FPGA fabric to drive a software logic analyzer.
• Active Probe allows dynamic asynchronous read and write to a flip-flop or probe point. This
enables a user to quickly observe the output of the logic internally or to quickly experiment on how
the logic will be affected by writing to a probe point.
• Memory debug gives the ability to perform dynamic asynchronous reads and writes to a micro
SRAM or large SRAM block so the user can quickly verify if the content of the memory is
changing as expected.
SmartDebug features can be accessed from within the Libero design flow or FlashPro software.
