attribute LOC of
HI All,
Iam trying to allocate the FPGA pins to my nets in the VHDL
Iam using the attribute LOC commands
just like:
attribute LOC : string;
attribute LOC of clock : signal is "p91";
that's ok and it's working but when iam trying to allocate pins for a
std_logic_vector here is the problem
If i -for example - defined in my entity
data : inout std_logic_vector(15 downto 0);
and tried to use the attribute for assigning pin locations for my data bus
using :
attribute LOC : string;
attribute LOC of data(0) : signal is "p133";
attribute LOC of data(1) : signal is "p137";
.
.
It doesn't work and compiler give me error
I think that the error in the form of the bit_vector
I have tried to write data<0> instead of data(0) but it didn't work also
can any body help
