Hi,
I have defined associative array using <*> " int array <*> " .
While assigning value to the array I am using int datatype
int i;
for (i = 0; i < 7; i++) begin
array = $urandom;
$display(" Printing Int Index Array ",array);
end
Now, when I want to access the above associative array using bit<2:0> data type then questa gives me below warning
# ** Warning: (vsim-3829) assoarray.sv(19): Non-existent associative array entry. Returning default value.
# Printing bit Index Array 0
This works in VCS!!! (VCS do implicit casting of bit<2:0> to int data type, whereas questa does not.)
So, I am not able to conclude which tool is having problem (Whether questasim OR VCS)?
On top of this I found that questasim works fine if I define associative array as " int array".
?????
Thanks,
Vaibhav

Vaibhav,
You are not showing enough code, and this forum is really bad for displaying Verilog code. I suggest contacting Mentor directly, or using another forum.
I will suggest that you do not use the wildcard index '*' and use a specific type instead. The wildcard index does not have a type and cannot be used with many other SV constructs, like foreach. VCS appears to work in some cases, but not all. |
