# 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.

#

# Exceptions for a testcell are defined by additional files.

#   no_gen   : don't execute the generic/default testbench tb_behav_c0

#   no_t48   : don't execute the t8048 testbench tb_t8048_behav_c0

#   no_t39   : don't execute the t8039 testbench tb_t8039_behav_c0

#   no_t41   : don't execute the t8041 testbench tb_t8041_behav_c0

#   no_t41a  : don't execute the t8041a testbench tb_t8041a_behav_c0

#   no_t42ah : don't execute the t8042ah testbench tb_t8042ah_behav_c0

#   no_dump_compare : don't include testcell when running dump compares

#   io_exp : use the testbenches containing the t8243 IO expander

#            tb_t8243_behav_c0
