Verification of FDU block In Video-SoC

NAME:

SoC For Video Application.

DOMAIN / CATEGORY:

Silicon Engineering / Consumer

TOOLS:

VCS

APPLICATION:

Video SoC

PROJECT DESCRIPTION : Verification of DMA-FDU in VIDEO SOC.

  • This chip is used in server as a result cache level is increased and external slaves are very large memories to store the data.
  • CCN was used so that there is no bus constraints.
  • CCN works on Round Robin node and has different slaves connected to different nodes
  • Performance limitation => Speculation access from snoop control unit/cluster was coming out as Zero address for core-1, which was not accepted as per the design intent

ROLE : Verification of following is within scope for Blueberry

  • Verification
  • AHB Certification
  • QNS Certification(AXI4 Lite)
  • Verification of FDU block with
  • Stall
  • Performance
  • Write_Read
  • Stream

CHALLENGES :

  • Cache analysis of Multi-core & Multi-Master
  • Data flow analysis in proprietary MESH network interconnect

ACHIEVEMENT :

  • Reduced time2debug by – Proactively developing debug assist-automation of CPU subsystem
