Intel HLS - simulating the design with ModelSim

[Mopplikus]

Hello,

I have generated a design using Intel HLS, and now I'd like to look at the corresponding wave graphs in ModelSim / QuestaSim. Since for the co-simulation a test-bench has already been generated, I normally shouldn't need to create a new one, so how do I go about 'hijacking' the existing test-bench to get to the wave graph?

By the way, I'm using version 21.4.0 of the HLS.

Thanks in advance!

Hi,

I am working on this issue. please give me time.

Hello,

I found the solution to my issue. For instance, I needed to add the -ghdl flag to the i++ command, which then generates a .wlf file in the verification folder, which I can then open with ModelSim. For future reference, to get the wave graph, you have to choose the instance of your top level component, and then in the Objects tab you can add the waves for the signals you need.

I'm encountering another issue now however; for instance, no matter the target frequency I specify, in the wave graph it is always set to 1000MHz, even if I override it with the --clock flag when compiling or for the individual components with hls_scheduler_target_fmax_mhz(). How could I fix this?

Hi,

in bellow article you can see setting target frequency details. please go through the document.

if you are facing the same issue after following the steps please share the details with screenshots.
