The roadtest about my adventures in Vivado together with the Digilent ARTY S7 board continues.
I just re-found a feature that might help during very low level debugging and system testing: the dashboard.
It is accessed through the hardware manager, when connected to a board.
- Open the 'Hardware Manager' from the Flow Navigator panel and connect to your board. I am not sure which devices support this feature, but the Spartan7 and all Zync do.
- Connect to your device to establish communication between Vivado and the target.
- Double click the XADC to open the dashboard window.
- From the '+' icon you can select the temperatures and voltage rails to be monitored.
This opens the dashboard window and gives a nice graph. The displayed information is helpful during debug to see if any voltage rail drops during high chip activity (e.g. a RAM stress test) or any over-temperature condition that might cause instabilities.
Next time I am going to talk about J9 or how to implement the SDRAM interface in VHDL on the ARTY S7.
