SiFive System IP
Insight™

Multi-world Hardware Isolation for System Security

SiFive Insight is an advanced trace and debug portfolio designed to simplify and accelerate the hardware and software validation of standalone SiFive RISC-V designs and complex mixed-vendor environments without altering critical execution timing. Standard with all SiFive Core IP licenses, its base framework delivers essential run control, core interrogation, and up to 16 advanced core triggers via a central Debug Subsystem.

  • Standard Debug Module (DM) for Run Control and Security.
  • Advanced Trace Encoder (Nexus 5001 Compliant).
  • Native Arm® CoreSight™ Compatibility.
  • Included with all SiFive Core IP licenses.

SiFive Insight

Features

External Debug Ports: Debug over JTAG, 2-wire cJTAG, or ARM-compatible AMBA APB interfaces. 

Advanced Core Triggers: Up to 16 hardware breakpoints and 16 external cross-triggers per core to halt or resume based on events. 

System Bus Access (SBA): Optional, non-intrusive memory access block for real-time variable read/write without affecting CPU cores. 

Nexus Trace Encoding: Supports open IEEE-ISTO 5001 standard address/opcode compression with selectable Branch Taken Messages (BTM) or History Trace Messages (HTM). 

Zero-Overhead Event Trace: Tracks call/return sequences, exception boundaries, context changes, and interrupts with timestamps with no software instrumentation.

Profiling Performance Counters (PPC): Tracks hardware counters and provides metrics between definable events.

Multilayered Debug Access Control: Enforces strict TAP security through fused permanent disable pins, 32-bit password barriers, or public-key cryptographic authentication.
