unexpected token

what is wrong with following code? i keep getting an unexpected token error message pointing to the condition statement, something to do with '=' ?????

reg count = 16;

always @ (posedge clk)
begin

if (start)

count = (count > 0) ? count-1 : count =16;
else
count = 16;

end
 

Re: unexpected token

from definition, count can't receive other values than 0 or 1.
Try reg [4:0] count
 

Re: unexpected token

actually that was a typo in my haste to post the problem.

my code actually has it assigned as a 5 bit reg.

reg [4:0] count = 16;

always @ (posedge clk)
begin

if (start)

count = (count > 0) ? count-1 : count =16;
else
count = 16;

end

now call me stupid but i cant see anything wrong with this code. ITs indicating its the " = " on the following line.

count = (count > 0) ? count-1 : count =16;

unexpected token???????
 

Re: unexpected token

O.K., I see
count = (count > 0) ? count-1 :16;
