WebJun 17, 2014 · The & symbols is the concatenation operator in VHDL: newsignal <= zeros (newsignal'left downto newsignal'right+1) & '1'; If you want to concatenate another signal, then it's even easier: newsignal <= zeors (newsignal'left downto oldsignal'left+1) & oldsignal; This extends oldsignal to whatever length newsignal is.
