I can’t get this line of code to work:

result <= (a * b)(31 downto 16);

the compiler (ghdl) suggests there’s a missing ‘;’ after the first ‘)’

a, b and result are unsigned 16 bit.

any suggestions?

Obviously I could do the multiplication first then slice on a new line (it’s happy with that), but even chatgpt thinks it should work as is.

I tried:

result <= (a * b)(31 downto 16);

I expected no errors.

I got an error: missing “;” at end of statement
