New ContributorI want to run my AFU in uClk_usr domain in the Streaming DMA AFU sample example. Please can you provide the steps that need to be followed in order to achieve this.
Thank you

Regular ContributorHi,
May I know which acceleration card and software stack are you using?
New ContributorRegular ContributorHi,
If you are refering to https://www.intel.com/content/www/us/en/docs/programmable/683424/2-0-1/hardware-subsystems.html then the AFU is already connected to uClk.
New ContributorHi,
We are referring to the same document. But I'm afraid they're using pClk for the entire design.
Specifically, we wanted a guide or a series of steps which will help us in taking uClk_usr signal as an input signal in hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv file. The uClk_usr signal is present as input in hw/rtl/ccip_std_afu.sv but we are finding it difficult in order to correctly take it as input in the avst_decimator.sv file.
Thank you
Regular ContributorHi,
Can you confirm if the "afu.sv" is using afu_clk?
New ContributorHi,
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
Regular ContributorHi,
Where can I get the avst_decimator.sv file? I am not able to see the file in the AFU design.
New ContributorHi,
Path to avst_decimator.sv is:
<path to streaming_dma_afu folder>/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv
OR
$OPAE_PLATFORM_ROOT/hw/samples/streaming_dma_afu/hw/rtl/QSYS_IPs/avst_decimator/avst_decimator.sv
Thank you
Regular ContributorHi,
May I know if you are using DCP 2.0.1? For this version, I do not see this IP
New ContributorHi,
I am not sure about the DCP Version.
We are accessing the streaming dma afu folder by:
1. SSHing into devcloud
2. "devcloud_login" into "Stratix 10 PAC Compilation and Programming - RTL AFU, OpenCL" node
3. Performing "tools_setup" of "Stratix 10 PAC Compilation and Programming - RTL AFU, OpenCL"
4. cd "$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
