This is the testbench for the idct implementation.

I found an ieee1180 test program for the jpeg idct, and modified it as follows:
- write idct input to file
- execute iverilog simulation of idct
- idct simulation writes idct output to file
- read idct output from file
compares verilog idct implementation  with floating point idct results, and prints worst error , mean error, mean square error.

compile verilog files into idct-verilog:
iverilog -o idct-verilog *.v
compile c test program:
run tests:
./doieee ./ieeetest
