The bits that make up the ALUFN (sub, bool, shft, Math) should be given separately in binary, and remember that the bool signal is a 2-bit value. Any signal value that doesn't matter should be indicated as an X. (If the 2-bit bool value doesn't matter, it should be indicated as XX.) For PCSEL, WASEL, ASEL and WDSEL, please indicate the value as a decimal number, e.g., 0, 1, 2, etc., unless it doesn't matter, in which case indicate it as X.
