I am using hardware co-simulation now , and I find xapp1031.pdf is very helpful. But I have a question that how to measure simulation time with system generator for hardware co-simulation?

Could anyone help me ?

Thanks!

hi,

try this:

tic;

sim('mymodel.mdl'); % a model consisting of your hwcosim block

toc;

This way I made a comparision between hwcosim and software simulation, which can also be found in the xilinx forums.

Have a nice simulation

Thank you very much!

I find it very helpful to me!

But I still have a question.

How can I measure the data trasmission time between PC and FPGA board?

Hi, could you offer me the link of your example, Thank you!

Hi,

there's no example available online.

But I think you have managed it now, since using a .m script is no big deal.

What interface are you using?

LAN? Use ethereal/wireshark.

JTAG? If not also covered by the above tool you might simply use an oscilloscope to inspect the TCL, TDI and TDO lines.

Or for a deeper inspection, and cheaper than an oscilloscope, there's another cool tool:

Thank you very much! I will try it now. By the way , I am using JTGA.
