Procedure to add uClk_usr in Streaming DMA AFU

Hi,

We tried using uClk_usr instead of pClk in line 117 of "ccip_std_afu.sv" file. We got the following error when we ran the software in simulation mode:

Thank you

Hi,

Sorry, I was looking at the wrong directory. After looking at the correct directory then I am able to find the file.

You can modify the file in ccip_std_afu.sv so that the AFU IP is using UserClk and not Pclk.

Hi,

Upon checking, the "avst_decimator.sv" file does not have user clock as input in this version as well.

Thank you

Hi,

Could you try to download the official version and check if you can work with the latest AFU design?

Hi,

I am not sure about the DCP Version.

We are accessing the streaming dma afu folder by:

1. SSHing into devcloud

2. "devcloud_login" into "Stratix 10 PAC Compilation and Programming - RTL AFU, OpenCL" node

3. Performing "tools_setup" of "Stratix 10 PAC Compilation and Programming - RTL AFU, OpenCL"

4. cd "$OPAE_PLATFORM_ROOT/hw/samples/streaming_dma_afu"

The path to avst_decimator.sv is
"$OPAE_PLATFORM_ROOT/hw/samples/streaming_dma_afu/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv"

Expanded path is "/glob/development-tools/versions/fpgasupportstack/d5005/2.0.1/inteldevstack/d5005_ias_2_0_1_b237/hw/samples/streaming_dma_afu/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv"

Thank you

Hi,

May I know if you are using DCP 2.0.1? For this version, I do not see this IP

Hi,

Path to avst_decimator.sv is:

<path to streaming_dma_afu folder>/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv

OR

$OPAE_PLATFORM_ROOT/hw/samples/streaming_dma_afu/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv

Thank you

Hi,

Where can I get the avst_decimator.sv file? I am not able to see the file in the AFU design.

Hi,

Yes, "afu.sv" is using the afu_clk.

But, it would be great if the uClk_usr is made available in avst_decimator.sv file.

Thank you
