JTAG Interface

The TEBF0808 carrier board provides several JTAG interfaces to program both the System Controller CPLDs and the Zynq Ultrascale+ MPSoC.

Therefore, the board is equipped with two JTAG/UART headers, which have 'XMOD FTDI JTAG Adapter'-compatible pin-assignment. So in use with the XMOD-FT2232H adapter-board TE0790 the mounted SoM and the System Controller CPLDs can be programmed via USB interface.

The System Controller CPLDs will be programmed by the XMOD-Header J28 in a cascaded JTAG chain as visualized in Figure 9. To program the System Controller CPLDs, the JTAG interface of these devices have to be activated by DIP-switch S4-3.
The 4 GPIO/UART pins (XMOD1_A/B/E/G) of the XMOD-Header J28 are routed to the System Controller CPLD U17.

XMOD-Header J12 is designated to program the Zynq Ultrascale+ MPSoC via USB interface, the 4 GPIO/UART pins (XMOD2_A/B/E/G) of this header are routed to the System Controller CPLD U39.

Further JTAG interfaces of the TEBF0808 carrier board are the ARM JTAG 20-pin IDC connector J30 and on the FMC Connector J5. This JTAG interfaces are connected to the System Controller CPLD U17, hence the logical processing and forwarding of the JTAG signals depend on the SC CPLD firmware. The documentation of the firmware of the SC CPLD U17 contains detailed information on this matter.

On-board Peripherals

System Controller CPLDs

The TEBF0808 is equipped with two System Controller CPLDs - Lattice Semiconductor LCMXO2-1200HC (MachXO2 Product Family) - with the schematic designators U17 and U39.

The  SC-CPLD is the central system management unit where essential control signals are logically linked by the implemented logic of the CPLD firmware, which generates output signals to control the system, the on-board peripherals and the interfaces. Interfaces like JTAG and I²C between the on-board peripherals and to the FPGA-module are by-passed, forwarded and controlled by the System Controller CPLD.

Other tasks of the System Controller CPLD are the monitoring of the power-on sequence and to display the programming state of the FPGA module.

Both System Controller CPLDs are connected to the Zynq Ultrascale+ MPSoC through MIO, PL IO-bank pins and I²C interface. The CPLDs are connected with each other through the IO pins SC_IO0 ... SC_IO8.

The functionalities and configuration of the pins depend on the CPLDs' firmware. The documentations of the firmware of SC CPLD U17 and SC CPLD U39 contains detailed information on this matter.

Following block diagram visualizes the connection of the SC CPLDs with the Zynq Ultrascale+ MPSoC via PS (MIO), PL bank pins and I²C interface.

Figure 13: Power-On Sequence Utilizing DCDC Converter Control Signals

The TEBF0808 carrier board manages both the power-on sequence of the mounted TE0808 / TE0803 SoM and the on-board DC-DC converters via System Controller CPLD U39.

The power-on sequence of the TE0808 / TE0803 SoM is managed by utilizing the SoM's DC-DC converter control signals ('Enable', 'Power-Good'), so the DC-DC converters of the SoM dedicated to the particular Power Domains of the Zynq Ultrascale+ MPSoC will be powerer-up in a specific sequence to meet the recommended criteria to power up the Xilinx Zynq Ultrascale+ MPSoC properly.

Core voltages and main supply voltages of the Zynq Ultrascale+ MPSoC have to reach stable state and the "Power Good"-signals of the SoM have to be asserted before other voltages like bank's I/O voltages (VCCOx) can be powered up.

It is important that all PS and PL I/Os are tri-stated at power-on until the "Power Good"-signals are logically high, meaning that all on-module voltages have become stable and module is properly powered up.

Adjustable PL Bank VCCO Voltage FMC_VADJ

The carrier board VCCO voltage 'FMC_VADJ' supplying the PL IO-banks of the MPSoC is provided by DC-DC converter U8 and selectable by the pins 'FMC_VID0' ... 'FMC_VID2' of the System Controller CPLD U17.
