11.1.7. Debugging Your OpenCL Library Through Simulation (Preview)

The Intel® FPGA SDK for OpenCL™ simulator assesses the functionality of your OpenCL* library.

The Intel® FPGA SDK for OpenCL™ simulator generates a .aocx file that runs on an x86-64 Windows or a Linux host. This feature allows you to simulate the functionality of your kernel and iterate on your design without needing to compile your library to hardware and running on the FPGA each time.

Note: The performance of the simulator is very slow when compared to that of hardware. So, Intel recommends using a smaller data set for testing.

Use the simulator when you want insight into the dynamic performance of your OpenCL* library and more information about the functional correctness of your OpenCL* library than emulation or the OpenCL reporting tools provide.

The simulator is cycle accurate, has a netlist identical to generate hardware, and can provide full waveforms for debugging. View the waveforms with Siemens* EDA Questa* software.
