# Purpose:

# ========

#

# Runs regression suite over all testcells found in $VERIF_DIR.

#

# run_regression.pl [-d]

#  -d : Perform a dump compare on each test with the i8039 simulator.

#

# The testcells are identified by searching for the .asm file(s).

# Each testcell is built by calling the central Makefile.cell.

# The resulting hex-file is then copied to $SIM_DIR where the VHDL simulator

# is started.

#
