Hello All, When you convert to Verilog, I see that `timescale 1ns/10ps near the top of the file .I don't see any timing information when you convert to VHDL. On the CAT-Board the default clock is 100MHz & on XulA2-LX9 the default clock is 12MHz.With the DCM I convert to 120MHz. For my simulation my clock is always 20nsec or 50MHz. Why? Can someone explain? @always(delay(10)) def clkgen(): clock.next = not clock If my simulation takes 1m35.611s using pypy, but total simulation time is 9139190 ns. What is the FPGA time? What is taking most of time? Modified to send more values to simulation. Now pypy is 2.3 times faster than python. pi@mysshserver ~/jpeg-2000-test/pc_fast_blinker_jpeg $ time python test_top.py --test real 3m38.582s user 3m36.950s sys 0m0.630s pi@mysshserver ~/jpeg-2000-test/pc_fast_blinker_jpeg $ rm -f tb.vcd*pi@mysshserver ~/jpeg-2000-test/pc_fast_blinker_jpeg $ time /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy test_top.py --test real 1m35.611s user 1m34.780s sys 0m0.800s Thanks, Edward Vidal Jr. e-mail dev...@sb... 915-595-1613 On Tuesday, January 26, 2016 2:51 PM, Edward Vidal <dev...@sb...> wrote: Hello All,I was reading David's post and found it very interesting. I tested on a RPi2B and did not get the results that David posted. At first, I thought the Pillow was taking all of time. My question, what would taking all of time? These are the steps that I used.

Did I fail to do something?https://github.com/develone/jpeg-2000-test/tree/master/pc_fast_blinker_jpeg Do you not get the benefit, until you exceed the time, to convert the python to compiled? Initially I was only testing a few values. To do the complete image the test bench will grow very quickly.
