System Control IP Core
This is small IP Core to help setting up fixed hardware functions on TE0841 and to communicate with the System Controller CPLD. This care provides optional Interface ports to attach to System Controller (MicroBlaze MCS based Microcontroller running System Control Firmware).
SoM Settings:
- Oscillator Enable
- DDR4 Power Control
- GT Transceiver Power Control
The above settings can be set to to:
- Fixed OFF/Disabled
- Fixed ON/Enabled
- User Control
- MicroBlaze MCS Control
System Control Unit
Xilinx MicroBlaze MCS can optionally be used as System Controller for various functions. This System Controller can be considered similar to PMU subsystem in Xilinx Zynq MPSoC devices. Main function of the System Controller is PLL Initialization and optional monitoring.
Example Design
All Interfaces visible are connected by Vivadi Board automation, the SYS interface includes all TE0841 fixed on-board connections that the System Controller

manages. SYSCONTROL is a small MicroBlaze MCS based controller that does initialize the Si5338 PLL Multisynth and can perform other functions as well.
