im trying to write an If STATEMENT in VHDL but i get an error i dont understand....Please help: if( c(2 DOWNTO 0) = "0 1 0") THEN F(6 DOWNTO 0) = "0 0 0 0 0 1 1"; error i get is: Error (10500): VHDL syntax error at lab1part4.vhd(29) near text "if"; expecting "end", or "(", or an identifier ("if" is a reserved keyword), or a concurrent statement cheers
Honored Contributorthe format of if is like this:
if (a)then ---- elsif(b)then ---- else ---- end if; so you need an "end if!"Honored ContributorHonored ContributorApart from missing "end if" and wrong assignment syntax, there are probably more VHDL errors.
- don't use spaces in VHDL constants like "0 1 0", - the error message "expecting ... a concurrent statement" suggests, that the statement is misplaced in your code. It's only valid inside a process. As a general suggestion, start with a VHDL text book or tutorial. Use the language templates in Quartus Editor to check for correct VHDL syntax.
