For significantly better performance, split this into 2 separate signals:

and change all receiving logic to instead receive "xout". Alternatively,

that widths inside concatenates and replicates must be sized, and should be
fixed in the code.
wire [63:0] concat = {1,2};

An example where this is technically legal (though still bad form) is:

wire [63:0] concat = {PAR,PAR};
wire [63:0] concat = {PAR, PAR};
The correct fix is to either size the 1 ("32'h1"), or add the width to the
