Unresolved reference to 'glbl' in glbl.GTS. Error!!!

[Vick]

I am getting the above error while simulating my verilog files along
with the following components:

IOBUF_F_12.v (at line--> tri0 GTS = glbl.GTS
OBUF_F_16.v (at line--> tri0 GTS = glbl.GTS


Any ideas to solve this problem... Is it because that glbl.v file has
not been compiled properly!

Thanx

I use Unisim components similar to those, and they work fine for me.

Did you remember to instantiate glbl somewhere?

If not, just add this line to your testbench:

glbl glbl (); // needed to get unisim components to work properly

You can also load specify it as a second design unit to be loaded when
starting the simulator. Then you do not have to change the testbench.
