Hello all, 

 

I am using modular scatter-gather DMA core to transfer data from my custom IP: custom_design_32_0 to other custom IP: custom_design_32_1 on the stratix 10 development board. 

 

Anybody please verify and suggest me that , Is connections are ok ? 

 

 

Regards, 

Anil

That screenshot is so small I cannot tell which IP in that system is the mSGDMA. In general you hook up a host like the HPS, Nios, etc... to the csr and descriptor slave ports of the dispatcher, the read/write masters to your memory, and if you are performing a streaming transfer the data source/sink to your own streaming IP. 

 

Here is an example showing how the mSGDMA is hooked up to the HPS: https://www.altera.com/support/support-resources/design-examples/soc/fpga-to-hps-bridges-design-exam...
