barrel shifter

[Hendrik Greving]

Hi

I can perfom a << b in Verilog. But if I make SHL(a,b) (a,b = unsigned)
I get errors. Is it possible to define barrel shifters as easy as in
Verilog?

Thanks for help.

Regards,
Hen

numeric_std has:

function SHIFT_LEFT (ARG: UNSIGNED; COUNT: NATURAL) return UNSIGNED;
