simulating FFT core 9.0

I have configured an FFT core using Throttle Scheme: Real Time . After simulating the design, I realized that I needed to implement Throttle Scheme: Non Real Time. After changing to Non Real Time, my design simulation suddenly terminates after only 3 clock cycles. This was not the case with Real Time, where it executed for over 1000 clock cycles.

 

The only difference between the two FFT implementations from an instantiation/simulation point is the addition of the I/O signals: m_axis_status_tready, event_data_out_channel_halt and event_status_channel_halt in Non Real Time mode. I do not understand why changing throttle modes would casue the simulation to halt prematurely. Has anyone experienced this behavior before?

Re: simulating FFT core 9.0

Does the simulator throw an error or anything?

Re: simulating FFT core 9.0

what happens if you try to run another 100ns ? (ie type run 100ns into the command line?)
