make runsim
This calls ~/krnl_cbc/runsim_krnl_cbc_xsim.sh to run the simulation with the Vivado XSIM.
The following figure shows the control signal waveform of krnl_cbc. You can see that before ap_done is asserted, four ap_start pulses are issued. Then, four ap_continue pulses are issued to confirm the four ap_done flags. Because krnl_cbc has four internal processing pipes, it can accept four task requests and process them in parallel.
