The Ordering Part Number (OPN) for all configurations of the Reed-Solomon Encoder core targeting LatticeECP/EC
devices is REEDS-ENCO-E2-N1. Table 8 lists the netlists that are available in the Evaluation Package, which can be
downloaded from the Lattice web site at www.latticesemi.com.
You can use the IPexpress software tool to help generate new configurations of this IP core. IPexpress is the Lattice
IP configuration utility, and is included as a standard feature of the ispLEVER design tools. Details regarding the
usage of IPexpress can be found in the IPexpress and ispLEVER help system. For more information on the
ispLEVER design tools, visit the Lattice web site at: www.latticesemi.com/software.
