# Script to run Lattice Diamond on a Verilog source file and LPF constraints file, then run some extra commands
# to create debug/dump output for the design

# Based on Clifford Wolf's icecube.sh from Project Icestorm

# Usage:
# ./diamond.sh part design.v
# Currently supported parts:
#  - lfe5u-85
#  - lfe5u-45
#  - lfe5u-25

# Currently this script supports Linux only.

# You need to set the DIAMONDDIR environment variable to the path where you have
# installed Lattice Diamond, unless it matches this default.
