Hello,

I would like to as a question if anyone could help me. I was wondering
does anyone ever worked with multiple system generator block in xilinx
system generator. I don't know how to make a simulation.
I've done this. I created two blocks (subsystems). The first one
should work on 133MHz. I put system generator block in this subsystem
and I set right properties of the module that this block demands.
Another module (subsystem) should work at 40Mhz. this module also
contain system generator block with regularly set parameters. both
modules are placed in same simulation model file and multiple system
generator block is set regularly.

I wrote a testbench that will generate input variables for simulation.
but when I start it, some error is occurred. I got the message :"All
Xilinx Blocks must be contained in a level of hierarchy with a System
Generator Token".

i tried to put system generator Token or whatever it names is in the
top level of the simulation model but I got the same error.

have anyone ever worked with different colock domains in system
generator and multiple system generator module.
please help if you can

thank you
Zoran
