sliceKIT hardware manual
2.1 Multiple core boards
Additional sliceKIT core boards can be connected to the Chain slot on the first
board via the Square Slot on the second board, to add extra processing capability
and I/O through extra sliceCARDs. The first board is termed the Master and the
remaining boards are Slaves. When there is only one board, it is the Master.
2.2 Setup
For debugging, an xSYS adaptor board is connected to the Chain connector of the
Master board to allow connection of an xTAG-2 which provides a debug link from a
USB host.
The core board is powered by a 12V external power supply.
2.3 Power supply
Power input to the sliceKIT core board is via a standard barrel jack connector. A
standard 12V external power supply should be used to power the board. Each core
board requires its own 12V supply. This input supply is used to generate the main
5V board supply via a DC-DC converter.
The 5V board supply is then fed to all the slot connectors as well as powering the
core board itself. 3V3 and 1V0 supplies are be generated by DC-DC converters
from the 5V main supply.
The supplies are sequenced to ensure the power up sequence is 5V then 3V3 then
1V0. When the 1V0 supply is good, the system is released from reset.
The core board provides 3V3 and 5V at 0.25A each for a total of approximately 2W
per slice.
2.4 Debug
Debug of the system is via the xSYS adapter board connected to the Chain connec-
tor.
The JTAG signals are connected as shown below.
