Hello,
I try to write my code in a generic fashion,
and this causes that there are cases in which I have signals with null
range.
for example, if I have a signal :
SIGNAL a : std_logic_vector(X-1 downto 0);
then if X is 0, this is a null range vector, and this is ok.
when I use this way of writing in altera-quartus and modelsim, there is
no problem and I simply get a null range warning.
but it appears that mentor-precision doesn't support this.
do you know if null range is a vhdl feature that must be supported?
Thanks
Ravid
