I'm using ISE 6.2i and when ever i use a Block RAM I cant see the Ram output Data the error is Timing Violation Error : Setup time 0.000 ns violated on X_RAMB4_S16_S16 instance NCO_NCO_tf_tf.uut.RAMB4_S16_S16_inst.display_zero on CLKA port at simulation time 0.150 ns with respect to CLKB port at simulation time
0.150 ns. Expected setup time is 0.100 ns # Timing Violation Error : Setup time 0.000 ns violated on X_RAMB4_S16_S16 instance NCO_NCO_tf_tf.uut.RAMB4_S16_S16_inst.display_zero on CLKA port at simulation time 0.250 ns with respect to CLKB port at simulation time 0.250 ns. Expected setup time is 0.100 ns # Timing Violation Error : Setup time 0.000 ns violated on X_RAMB4_S16_S16 instance NCO_NCO_tf_tf.uut.RAMB4_S16_S16_inst.display_zero on CLKA port at simulation time 0.350 ns with respect to CLKB port at simulation time 0.350 ns. Expected setup time is 0.100 ns # Timing Violation Error : Setup time 0.000 ns violated on X_RAMB4_S16_S16 instance NCO_NCO_tf_tf.uut.RAMB4_S16_S16_inst.display_zero on CLKA port at simulation time 0.450 ns with respect to CLKB port at simulation time 0.450 ns. Expected setup time is 0.100 nsthe Enable pin is high and I change the Address but the out put is always
0 can any one help me with this ?? thanks THE UNFORGIVEN
