# This script runs the synthesis tests listed in the fpga_reg.list
# list file. The script uses Icarus Verilog from the path, and also
# gets ngdbuild and ngd2ver from the path. The XILINX variable needs
# to point to the XILINX install directory so that the simprims
# can be found. The run test uses these to generate a simulation
# from the synthesized file.
#
# Usage: sh ./fpga_reg.sh [select]
#
#  If there is no select, then run all the tests. If there is a select,
#  then only run the tests that match the select regular expression.
#

# This is a diff command for comparing log with gold files.
diff="diff --strip-trailing-cr -aq"

# This is the output file.
