Where is the package defined?











Hi,
I am using System Generator 10.1i. The generated code has multiple
times of the following similar code. I am curious about the definition
of:
use work.conv_pkg.all;
use work.clock_pkg.all;

I cannot find it anywhere. Anyone can tell me that?


Thanks in advance.
