What you practice
Attach DMA + IRQ to fabric (5.3). Attach DMA engine and IRQ lines to the SoC fabric by completing port connections in the design module. It is in Attach DMA and IRQ — Part 5 · Integration & Capstone of the SoC Masterclass. Tie a CPU stub, decode, peripherals, DMA, and IRQ into a mini-SoC capstone.
SoC lessons simulate the fabric and the peripheral together in the IDE. Verilator is the simulator; the waveform is where address and response show up.
Run it in the Verilog IDE
- Open the lesson workspace in the IDE. The fabric and the peripheral are one simulation.
- Run Verilator and follow the address, write data, and read response on the waveform.
- A passing log is not enough when decode or an IRQ line is the point of the lesson — those show up on the VCD.
- Run Yosys on the RTL island you just integrated when you want the mapped cells.
The lesson is done when the simulation matches Attach DMA + IRQ to fabric. Change the source, run the Verilog simulator again, and read the waveform without leaving the IDE. Simulation guide · Yosys guide.
