swizzle method
Performs a concatenation operation on the list of signals, where index 0 of this list is the most significant bit(s).
This is the one you should use if you're writing something like
SystemVerilog's {}
notation. If you call swizzle on [a, b, c]
you
would get a single output Logic where the bits in a
are the most
significant (highest) bits.
If you want the opposite, check out rswizzle.
Implementation
Logic swizzle() => length == 1 ? first : Swizzle(this).out;
