Modelsim simulation of System generator design

[spman]

Hello

I have a problem with modelsim simulation of a System generator design. I do vcom.do and vsim.do and simulation runs successfully. But I can't find signals of the design in object window. I want to view them in the waveform window. But object window is empty!
I have this problem with all designs created by system generator!
Thanks in advance

Maybe try add wave * ?

it could be that the design was compiled with optimisations on, causing the signals to be invisible.
Check the .do file and look for the vcom/vlog (vhdl or verilog compile commands) next to file you want the signals for, and add the option -novopts

Please use the +acc option on vcom/vlog/vopt to get access to signals you need, not the -novopt option, which globally turns of all optimizations.

Thanks to all
The signals were appeared by using the option -novopts with vsim command (not vlog). Could you please explain how to use +acc option? I couldnt find any useful instructions about it in the modelsim help.

You can either do

vcom +acc ...

or vsim -voptargs=+acc ...
