RocketIO Tile Configuration
The RocketIO Tile Configuration screen is only displayed if the RocketIO interface is used
with the Virtex-4 or Virtex-5 device families.
RocketIO transceivers for Virtex-4 FX and Virtex-5 device families are available in tiles,
each tile consisting of a pair of transceivers. The RocketIO Tile Selection has no effect on the
functionality of the core netlist, but determines the functionality of the example design
delivered with the core.
Depending on the option selected, the example design instantiates a single core netlist and
does one of the following:
•
MGT A (0) . Connects to RocketIO transceiver A
•
MGT B (1) . Connects to RocketIO transceiver B
•
Both MGTs . Two instantiations of the core are created in the example design and
connected to both RocketIO transceiver A and B.
Parameter Values in the XCO File
XCO file parameters are used to run the CORE Generator from the command line. XCO file
parameter names and their values are similar to the names and values shown in the GUI,
except that underscore characters (_) may be used instead of spaces. The text in an XCO file
is not case sensitive.
