1    d) Xilinx IP cores
3    The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
10    Each IP-core has a set of parameters which the FPGA designer can use to
11    control how the core is synthesized.  Historically, the EDK tool would

48    Typically, the compatible list will include the exact IP core version
