Simulating the I2C Controller

Hello Everyone, I am trying to simulate the I2C controller, but have problem as there is no slave to generate the acknowlege back. Can Anyone tell me how to get around this. Thanks...

Of course noone will know, what is causing the shown waveforms without seeing the code.

Apparently you are simulating in Quartus built-in simulator. This means, that a testbench with I2C slave model isn't an option. In this case, driving the SDA line low at a precalculated time and releasing it afterwards is the only way to simulate the slave's ACK response.

Seriously speaking, this kind of simulations demands for a full-featured simulator like Modelsim.
