Detailed Description

FPGA Common ID Module.

This module provides a number of registers to identify the board and the type and version of the firmware and XML files.

These registers include:

1. Module ID Register:
   • bit 31: 0 = golden image, 1 = user image
   • bits 30-28: fpga flavour, 0= cFPGA, 1 = pFPGA1, 2 = pFPGA2, 3 = pFPGA3, 4 = pFPGA4
   • bits 27-26: geographic address for process FPGAs only
   • bits 25-20: PCB serial number, control FPGA only
   • bits 19-16: shelf address from IPMC
   • bits 14-12: Slot address, bottom 4 bits
   • bits 11-0: Module code (should be 0xefe)
2. XML Version Register:
   • version: 32-bit register holding the version of XML files, Major.Minor.Patch
     • bits 31-24: major version
     • bits 24-16: minor version
     • bits 15-0: patch number
   • git_sha: 32-bit register holding the XML Git commit 7-digit SHA of top file
3. Build Date: 32-bit register holding Firmware build date
4. Build Time: 32-bit register holding Firmware build time
5. Firmware Version Register:
   • version: 32-bit register holding the Firmware Version Major.Minor.Patch
     • bits 31-24: major version
     • bits 24-16: minor version
     • bits 15-0: patch number
   • git_sha: 32-bit register holding the Git commit 7-digit SHA of the whole firmware repository
