I am looking for HPS to FPGA custom component integrations guideline using Qsys. I am new to SoC FPGA programming. I still could not found a material or tutorial for HPS to custom VHDL or Verilog com...

Honored Contributor --- Quote Start --- Thank you for sharing the document. I have already used that tutorial. In that tutorial Avalon memory map is used. In my system I am using ARM processor instead of NIOS. I am not sure whether I can interface my custom peripheral using Avalon memory map in the case ARM. I have come across posts saying interconnect bridges can solve this. But didn't find a document on that. --- Quote End --- Yes the QSYS will connect the peripherals correctly, both AXI and Avalon. I already tried it and it works. On ARM C coding, you will need a pointer that targets the address of that custom peripheral (with lightweight offset. Check the tutorials). Did you try to use the ARM with gpio or any pre-built peripheral from the QSYS tool?
