simulation not showing components of top level

hi,

i am new at design. i am trying to run a test bench on I2C slave code (openCore). for some reason, when i start simulation (ModelSim), it loads the design, but only the top level with non of its components i.e. my DUT..

for some reason it writes on the log -# Loading work.i2cSlaveTop(fast). on other projects i have run, there is no (fast). could this be the problem? any idea how to overcome it?

    when you run vcom or vlog, try adding the -novopt switch. it should turn off compilation optimasations that will allow you to navigate into the design.
