[SOLVED] even parity check with data flow operators

hi
I want to build even parity check for the data of size [7:0] with data flow operators ?
can anyone help me ,
thanx

Consider XOR operator...

like ,

Code:

assign parity_bit =(data_in[0]^data_in[1])^(data_in[2]^data_in[3])^(data_in[4]^data_in[5])^(data_in[6]^data_in[7]);

or

Code:

assign parity_bit =(data_in[7]^data_in[6])^(data_in[5]^data_in[4])^(data_in[3]^data_in[2])^(data_in[1]^data_in[0]);

so will use this statment without brackets

Code:

 assign parity_bit =(data_in[7]^data_in[6])^(data_in[5]^data_in[4])^(data_in[3]^data_in[2])^(data_in[1]^data_in[0]);

to get even parity ??

Yes. Brackets aren't needed.

Sure, even parity. Check yourself with pencil and paper method.

Instead of all that typing, use the reduction XOR operator e.g. assign even_parity = ^data_in
