General Notes:
If some section is CPLD firmware dependent, make a note and if available link to the CPLD firmware description. It's in the TE shop download area in the corresponding module -> revision -> firmware folder.

General Notes:
Designate all graphics and pictures with a number and a description. For example "Figure 1: TE07xx-xx Block Diagram" or "Table 1: Initial delivery state". "Figure x" and "Table x" have to be formatted to bold.

Rules for all diagrams:
1. All diagrams are wrapped in the "Scroll Title" macro.
- The title has to be named with the diagrams name
- The anchor has the designation figure_x, whereby x is the number of the diagram
2. The Draw.IO diagram has to be inserted in the "Scroll Ignore" macro
- Border has to be switched off in the macro edit
- Toolbar has to be hidden in the macro edit
3. A PNG Export of the diagram has to be inserted in the "Scroll Only" macro, see Wiki page "Diagram Drawing Guidelines" how to do this step.
The workaround with the additional PNG of the diagram is necessary until the bug of the Scroll PDF Exporter, which cuts diagram to two pages, is fixed.
IMPORTANT NOTE: In case of copy and paste the TRM skeleton to a new Wiki page, delete the Draw.IO diagrams and the PNGs, otherwise due to the linkage of the copied diagrams every change in the TRM Skeleton will effect also in the created TRM and vice versa!
See page "Diagram Drawing Guidelines" how to clone an existing diagram as suitable template for the new diagram!

USB-C
Front panel USB-C Interface connected to USB FIFO bridge chip FT601Q. 32-bit FIFO bridge provides a simple high-speed interface to Zynq UltraScale+ PL.
Front panel Micro-USB Interface provides access to UART and JTAG functions via FTDI FT2232 chip. Use of this feature requires that USB driver is installed on your host PC. UART0 with MIO 22 .. 23 should be selected in "Zynq UltraScale+ MPSoC" configuration.
The Digilent plug-in software and cable drivers must be installed on your machine for you to be able to use JTAG interface.

SD
There are some limitations to use SD card Interface in Linux.
Zynq UltraScale+ SD controller is working only in the 3.3V mode as it connected to SD card socket using 1.8V to 3.3V level shifter U10.
Micro SD card socket has no "Write Protect" switch.
Tip
To force Linux driver not to use this features add following instructions to device tree file.
&sdhci1 {
no-1-8-v; disable-wp; };

Power Consumption
The maximum power consumption of a module mainly depends on the design running on the FPGA.
Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.
