Signal related problem ----Stop the output (Urgent)

--- Quote Start ---

module simplemotion(motion,key_0, CLK_50M,VCC);

output motion;

input key_0;

input CLK_50M;

input VCC;

slowclock(CLK_50M, pulse);

wire pulse;

reg motion;

always @(posedge pulse)

if (key_0==1)

motion = pulse;

stop(CLK_50M,c);

wire c;

always @(posedge c)

if (c==1) motion =0; // in this step i am trying to stop the motion , however, i couldn't because motion cannot be multiple constant.

endmodule

module stop(CLK_50M,c);

input CLK_50M;

output c;

reg [20:0] count;

always @(CLK_50M)

count = count+1;

assign c = count[20];

endmodule

module slowclock(CLK_50M, pulse);

input CLK_50M;

output pulse;

reg [15:0] counter;

always @(posedge CLK_50M)

counter<=counter+1;

assign pulse = counter[15];

endmodule

My code is wrong, i have been working on this for weeks, still can't stop sending out the pulse to the motor at some specific time.

Can anyone help? Thank you.

Hi,

It seems to me the problem with your output c. Better to declare before the call . Please check by displaying before stop call and after stop call. In this way, you will get know the problem why it is not stopping.

HI, kkr, Thanks

I have already declared c as wire,

i can't compile it , it said Error (10028): Can't resolve multiple constant drivers for net "motion" at step.v(27)

My will is to stop sending pulse to the motor,,,,,however i can't...Do u know why

you just remove down declaration, and declare only above stop.

iT'S NOT WORKING...

i just want to stop sending out the pulse
