Using Monte Carlo in bertool the plotted Ber curve is coming as a horizontal line and sometime is constant values over Eb/No. Why?

In channel coding without consider modulation/ demodulation simulation model,when I am plotting the BER vs Eb/No graph using Monte Carlo of bertool, I get a horizontal line or constant values as straight line? Thank you.
