7- Segments pin assignment for Cyclone IV EP4CE6E22C8

Hello:

I wrote simple program to count on 7 Segments Display in my board Cyclone IV EP4CE6E22C8.

module seg(
    input clk,
    output segA, segB, segC, segD, segE, segF, segG, segDP
);
reg  cnt;
always @(posedge clk) cnt <= cnt+24'h1;
wire cntovf = &cnt;
reg  BCD_new, BCD_old;
always @(posedge clk) if(cntovf) BCD_new <= (BCD_new==4'h9 ? 4'h0 : BCD_new+4'h1);
always @(posedge clk) if(cntovf) BCD_old <= BCD_new;
reg  PWM;
wire  PWM_input = cnt;
always @(posedge clk) PWM <= PWM+PWM_input;
wire  BCD = (cnt | PWM) ? BCD_new : BCD_old;
reg  SevenSeg;
always @(*)
case(BCD)
    4'h0: SevenSeg = 8'b11111100;
    4'h1: SevenSeg = 8'b01100000;
    4'h2: SevenSeg = 8'b11011010;
    4'h3: SevenSeg = 8'b11110010;
    4'h4: SevenSeg = 8'b01100110;
    4'h5: SevenSeg = 8'b10110110;
    4'h6: SevenSeg = 8'b10111110;
    4'h7: SevenSeg = 8'b11100000;
    4'h8: SevenSeg = 8'b11111110;
    4'h9: SevenSeg = 8'b11110110;
    default: SevenSeg = 8'b00000000;
endcase
assign {segA, segB, segC, segD, segE, segF, segG, segDP} = SevenSeg;
endmodule

then i connect these pin assignment

clk --> pin 24

segA --> 143

segB --> 144

segC--> 141

segd --> 142

segF -->138

segG -->2

segDP --> 3

after i run this code , only the blue small LED works not the 7Seg !!

now how can i run the 7 Seg ?

also how can i count the & seg by pressing the push bottom ?

thank you
