Versions:
QtRvSim 0.9.8, released by Czech Technical University, is an open-source RISC-V CPU simulator engineered specifically for computer-architecture education, providing a graphical pipeline view, register file inspection, memory-monitoring widgets, and integrated assembler/disassembler that let students step through RV32 and RV64 instructions cycle-by-cycle to visualize how fetch, decode, execute, memory and write-back stages interact inside a five-stage scalar core. Instructors routinely embed the tool in undergraduate and graduate courses on digital design, microprocessor systems, and system-on-chip curricula: lecture slides link to pre-built ELF binaries so learners can single-step benchmark kernels while waveform diagrams update in real time; laboratory assignments ask students to extend forwarding logic, insert pipeline bubbles, or implement hazard detection and then measure CPI changes immediately within the same GUI; research groups leverage the deterministic tracer to validate custom RISC-V extensions before moving to FPGA prototypes, while online MOOC forums distribute homework templates packaged as portable QtRvSim projects that participants execute on Windows, macOS, or Linux without installing heavyweight IDEs. Because the simulator exports memory maps as plain text and supports the standard RISC-V ELF format, it also interoperates with GNU toolchains, Spike, and OpenOCD, making it a lightweight companion to more complex RTL workflows. The single maintained version 0.9.8 continues to receive minor patches that refine CSR semantics and increase compatibility with recent privilege specifications. QtRvSim is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest 0.9.8 build and supporting batch installation alongside other educational or development utilities.
