 * $read_test_vector example -- Verilog HDL test bench.
 *
 * Verilog test bench to test the $read_test_vector PLI application.
 * NOTE: this test uses two data file, "read_vector_test1.pat" and
 * "read_vector_test2.pat".  Each file has several 8-bit binary test
 * vector values (represented in ASCII).
