# Here we re-define the modelsim compilation variable, changing include dirs 
# so we use the includes/defines from the board's rtl path instead of the 
# normal orpsocv2 bench path.


# Modelsim testench compilation - we change this from the standard makefile
# to change:
# 1) The include directory (should be the board RTL path, not the main RTL path)
# 2) Change the define for the name of the top testbench (board dependent)
# 3) Add the board's testbench paths
# 4) Add the various extra memory models we use (maybe should just use a script for this instead? TODO!)
