I have a question. What is the range of integer in GHDL?
Try: ghdl --disp-standard and look for integer: type integer is range -2147483648 to 2147483647;
This works (wert>2^31): signal wert: std_logic_vector(31 downto 0):= X"ffff0000"; signal a: integer:= to_integer(unsigned(wert));
There are some undetected overflow during the conversion.
This produce an error (c=2^31): signal c: integer:=2**31; hometown.vhd:34:23: static constant violates bounds ghdl: compilation error makefile:4: recipe for target 'all' failed
But the overflow are detected during analysis. Tristan. _______________________________________________ Ghdl-discuss mailing list Ghdl-discuss@gna.org https://mail.gna.org/listinfo/ghdl-discuss
