uvm_config_prop

[chenyong]

Hi,

I found such codes as this:

package uvm_config_prop_pkg;

....

class uvm_config_prop #(type T=int) extends uvm_object;

.....

static function void set_config (string target, string field, T value, uvm_component cntxt=null);

uvm_config_prop #(T) wrapper = new(value);

....

endfunction : set_config

...

I was confused by the code with this:

uvm_config_prop #(T) wrapper = new(value);

how can a function belongs to a class to "new" a class as itself? Can anybody help me to understand this? thanks.

hi,

the magic of this is that the set_config is a static function (your are calling it upon the type and not upon an instance). so with that you say sometype::function() which calls function without having an instance. so this code is a static function which in its body allocates a dynamic object using new.
