In a State Machine Declaration in a Text Design File (.tdf), you assigned the specified numerical value to a state. The numerical value has more bits than you declared for the state, and therefore the value cannot fit in the state. This message can occur if you use a binary string with the wrong radix (for example, you use 110 or H"110" instead of B"110"). The Quartus II software attempted to fit the value into the state by removing from the value the MSB and as many adjacent bits as necessary. However, in removing the bits, the Quartus II software changed the value.

For example, the following State Machine Declaration causes this warning message:

ss :   MACHINE
       OF BITS (q1, q2, q3)
       WITH STATES (
         s1 = B"111",
         s2 = 128);

The state s2 has three state bits, but the decimal number 128 (the binary number 10000000) has eight bits. The Quartus II software either removes the first five bits of the number and assigns the binary number 000 (the decimal number 0) to s2, or removes the last five bits of the number and assigns the binary number 100 (the decimal number 4) to s2.
