These MMCM attribute settings result in a wide variety of synthesized clocks:

CLKOUT0_PHASE = 0;
CLKOUT0_DUTY_CYCLE = 0.5;
CLKOUT0_DIVIDE = 2;
CLKOUT1_PHASE = 90;
CLKOUT1_DUTY_CYCLE = 0.5;
CLKOUT1_DIVIDE = 2;
CLKOUT2_PHASE = 0;
CLKOUT2_DUTY_CYCLE = 0.25;
CLKOUT2_DIVIDE = 4;
CLKOUT3_PHASE = 90;
CLKOUT3_DUTY_CYCLE = 0.5;
CLKOUT3_DIVIDE = 8;
CLKOUT4_PHASE = 0;
CLKOUT4_DUTY_CYCLE = 0.5;
CLKOUT4_DIVIDE = 8;
CLKOUT5_PHASE = 135;
CLKOUT5_DUTY_CYCLE = 0.5;
CLKOUT5_DIVIDE = 8;
CLKFBOUT_PHASE = 0;
CLKFBOUT_MULT_F = 8;
DIVCLK_DIVIDE = 1;
CLKIN1_PERIOD = 10.0;

The following figure displays the resulting waveforms.
