The board module EVALXCS-PQ208 is an ideal tool to test complex digital
circuits during the early states of their development. The various configuration
options of the Xilinx FPGAs allow the easy implementation of applications.
The hardware configuration may be loaded via XChecker or SPROM. Almost
all I/O pins of the FPGA are routed to header connectors, a total of 150
signals. These signals may be used as inputs or outputs.
Several board modules may be stacked to form a tower which enables one
to realise circuits whose demand of gates is beyond the scope of a single
FPGA. By using an external daisy chain connection, the whole stack can
be configured at once with a single download operation.
Seven clock sources can be used whereas one clock source is either the
internal quarz oscillator or an external clock source. The quarz oscillator
is inserted in a socket and can therefore be exchanged easily. Both DIL-8
and DIL-14 packages can be used. All clock signals may be terminated (parallel
termination to ground) with termination resistors. These resistors can
be soldered to the bottom side of the PCB.
A four position DIP switch is available for user defined purposes. There
is also a push button whose primary intent is to serve as a reset button.
Since this button is connected to a general I/O pin it may be used for
arbitrary functions.
An LED row with eight SIDELEDs is able to display status messages, error
messages etc..
