GCM V5.0 :

  • GLOBAL

    • Switching "CERN-OHL v1.2" license to "CERN-OHLw v2 or later"
    • Renaming "librairies" folder to "libraries"

  • DOCUMENTS

    • Adding the GCM datasheet
    • Adding the CHANGELOG file
    • Adding waveforms
    • Cleaning

  • SCHEMATICS

    • Set version to 5.0
    • Replacing old custom "74CBTLV16212" symbol with the Kicad symbol "74CBTLV16212"
    • Replacing old custom "LTC6994-1" symbol with the Kicad symbol "LTC6994xS6-1"
    • Replacing old custom "LM810" symbol with the Kicad symbol "LM810"
    • Replacing all hidden power pins symbols (hidden pins bug)
    • Renaming "Main connector" to "SPS1 Processor connector"
    • Removing old symbols, cleaning
    • Replacing symbol "CD74AC238" with a new one
    • Replacing all used 74x1Gxx symbols
      (shared power pin fix, and visual)

  • PCB

    • Removing/Cleaning old footprints
    • Set version to 5.0
    • Fixing 3D
    • Adding QRCode with the Github link

  • SCHEMATICS FEATURES

    • Complete change of the clock generation
      Adding the "ECS-2200BX-500" crystal oscillator
      You will now be able to select : 50MHz
      or pre-division : /2, /4, /8, /16, /32, /64, /128, /256, /512, /1024, /2048, /4096, /8192, /16384, /32768, /65536
      Removing "~GLOBAL_CLK"
      More simple frequency control (switch to parallel control)
      Removing "LTC6903" (SPI frequency chip)
      Fixing unstable frequency change
      After a frequency change, the system now send a "SOURCE_RESET" pulse

      • Replacing "SN74LV163A" with "CD74AC161"
        Async reset
      • Put a Tpd delay to "ADDSRC_CLK"
      • "ADDSRC_CLK" is now directly connected to the CLK input of the 24bits counter

    • Renaming "ClockGenerator.sch" sheet to "fileClockGenerator.sch"

    • Renaming "Connector.sch" sheet to "fileConnector.sch"

    • Renaming "Peripherals.sch" sheet to "filePeripherals.sch"

    • Renaming "MemoryController.sch" sheet to "fileMemoryController.sch"

    • Renaming "MemorySlot1.sch.sch" sheet to "fileMemorySlot1.sch"

    • Renaming "MemorySlot2.sch" sheet to "fileMemorySlot2.sch"

    • Renaming "AddressCounter.sch" sheet to "fileAddressCounter.sch"

    • Renaming "AddressExchanger.sch" sheet to "fileAddressExchanger.sch"

    • Adding a seperate clock signal only for peripheral (PClockGenerator)

    • Applying PP1 standard for peripheral https://github.com/JonathSpirit/GComputer_standard

    • Applying MM1 standard for memory https://github.com/JonathSpirit/GComputer_standard

    • Mounting holes is now on schematics

    • Renaming "MAIN_RESET" to "POWER_RESET"

    • Renaming "SOURCE_RESET" to "LIGHT_RESET"

    • Renaming "RESET_CLK" to "GLOBAL_RESET"

    • MemoryController rework
      User can now control CE,WE,OE pins of the not selected memory source
      Applying MM1 standard, (3.3V)
      Renaming/Cleaning
