What you practice
MMIO load store (1.3). Measure MMIO store and load latency by connecting AXI interfaces in the design and verifying results in the testbench. It is in MMIO load/store timing — Part 1 · Core on Bus (MMIO) of the RISC-V on SoC & System Masterclass.
The core and the mini-SoC simulate as one workspace in the IDE. Follow MMIO, interrupts, and the program on the Verilator waveform, not only a pass line.
Run it in the Verilog IDE
- Open the system lesson in the IDE. The RV32I core and the mini-SoC fabric simulate together.
- Run Verilator and trace the program through MMIO: address, load/store data, and the peripheral response.
- Interrupts and DMA belong on the waveform next to the instruction stream, not only in a pass/fail line.
- Edit the integration RTL, resimulate, and run Yosys on the structural block when you want a netlist.
The lesson is done when the simulation matches MMIO load store. Change the source, run the Verilog simulator again, and read the waveform without leaving the IDE. Simulation guide · Yosys guide.
