SoC Proxy Technical Specification

SoC Proxy is a simple comportable IP module that facilitates the breakout of signals and buses internal to Dragonfly (similar to Sensor Control for AST).

Comportable Interfaces

• Clock / reset (intended for connection to the fast clock domain)
• 1 TL-UL Device port for comportable CSR node
• 1 TL-UL Device port with an address range to egress into CTN
• 1 Fatal alert for bus integrity
• 2 Wakeup requests
  • Internal wakeup request, should be asserted whenever an external alert or IRQ is seen
  • External wakeup request

SoC-facing interfaces

• Synchronous interfaces:
  • 1 TL-UL Host port for egress into CTN
  • 1 Wakeup request, asynchronous and level-encoded
  • 32 Interrupts, asynchronous and level-encoded
  • 16 general-purpose inputs
  • 16 general-purpose outputs
