4a.) Each test will test all its vectors - if you want to test a
subset of the vectors (e.g., only binary16), you should modify the
cvw/testbench/tests-fp.h and comment out the tests you do not want to
test. The best way to do this is to comment out each item out with
the // comment option in SV. For example,
string f128div[] = '{
// "f128_div_rne.tv",
// "f128_div_rz.tv",
// "f128_div_ru.tv",
// "f128_div_rd.tv",
// "f128_div_rnm.tv"
};
testfloat.do in the sim directory. Change the TEST_SIZE="all" to the
specific test you want to run. For example, if you want to run only
binary16, you should set this variable to TEST_SIZE="HP".
4b.) If you want to turn off the generation of wlf files while running
sim-testfloat-batch, you can modify testfloat.do in the sim
directory. Inside this DO file, modify the WAV file to 0 --> i.e.,
set "quietly set WAV 0;"
