How the simulator handle the 'X' logic?

[enchanter]

I got a piece of code from Xilinx coregen.

if ((not(IODRPCTRLR_RDY_BUSY_N)) = '1') then
    STATE <= WAIT4;
elsif (((not(ZIO_IN))) = '1' or (N_Term = "1111111")) then
    if (PNSKEW = '1') then       
        STATE <= SKEW;
    else
        STATE <= WAIT_FOR_START_BROADCAST;
    end if;            
else
    STATE <= INC_NTERM;
end if;

If

     IODRPCTRLR_RDY_BUSY_N = '1'
     ZIO_IN                            = 'X'
     N_Term                           = "1111111"
     PNSKEW                          = '1'

then what the value of STATE should be ?

STATE <= INC_NTERM
because X is not equal to 1

Hi Funzero:

thanks for your reply. But that is an OR logic. the N_Term = "1111111" is true.
