Hiiii harinisas,
If u cant see the output in waveform then there might be a combinational loop.... so checkout for these...
> I will give an example if declare a,b as wire's let 'c' be some other variable...
>> assign a = c & b ;
>> assign b = c | a ;
>> assign a = a & b;
If u see in the above assignments there is a loop as they goes on changes irrespective of clock and this creates a loop.... so check for these kind of loops...
