Appendix A:
Resource Utilization
This appendix gives resource utilization information for Lattice FPGAs using the Block Viterbi Decoder IP core.
IPexpress is the Lattice IP configuration utility, and is included as a standard feature of the Diamond and ispLEVER
design tools. Details regarding the usage of IPexpress can be found in the IPexpress and Diamond and ispLEVER
help systems. For more information on the Diamond or ispLEVER design tools, visit the Lattice web site at:

1. Performance and utilization data are generated targeting an LFEC20E-5F672C device using Lattice Diamond 1.0 and Synplify Pro
D-2009.12L-1 software. Performance may vary when using a different software version or targeting a different device density or
speed grade within the LatticeECP/EC family.
Ordering Part Number
The Ordering Part Number (OPN) for the Block Viterbi Decoder IP on the LatticeEC devices is VTERB-BLK-E2-U4.
