  3. Problem Statement • Verilog and SimpleScalar are tools that aid in the study of computer architecture, but they lack a flexible graphical user interface (GUI). • Professors in computer engineering at Iowa State would like to enhance the visualization of the computer architecture that the students are studying.

  4. Design Objectives Develop a GUI for a computer architecture simulator that: • Allows students to see the process of instruction execution. • Is simple to use and understand. Layers are used to show and hide information and to improve clarity.

  5. End Product Description • The product is a GUI educational tool for students studying micro-architecture. • It animates the execution of MIPS assembly programs cycle by cycle. • The animation is based on data generated by a Verilog simulation of the computer architecture. • Instructors can simulate new programs with the provided tools for distribution to the students.

  7. Assumptions and Limitations • The micro-architecture is limited to a simplified version of MIPS architecture as described in CprE 305. • Users are expected to be familiar with the MIPS instruction set. • Animations consist of less than 60 cycles. • The simulator must be capable of producing text output. • Screen size limits the effective display of information.

  8. Project Risks and Concerns Possible Risks: • Not finishing on time. • Losing a team member. • Pitfalls of learning a new language. Risks Encountered: • Complexity of the architecture. • Preferred version of Verilog hard to find. • Security issues with Java. • Source management.

  9. Simulator Translator GUI Technical Approach • Micro-architecture simulator (Verilog) • Translator (Perl) • GUI software (Java)

  10. Verilog Instruction Memories Verilog Output Assembly Source Code Assembler Verilog Model Technical Approach (cont.) Micro-architecture Simulation and Tools

  13. Recommendations for Further Work • Support advanced architecture features. • A server version of the software would allow students to submit their own code for animation. • Enhance the quality of the animation with multimedia.

  14. Evaluation of Project Success Milestones: • Assembler to create Verilog programs. • Verilog model of architecture. • Translator from Verilog to GUI. • GUI software. • User and Instructor Manuals • Code documentation.

  15. Project Success (cont.) Testing Approaches • System test • Evaluation test by graduate students and faculty: • Provides feedback on the effectiveness of the tool • Determines the suitability as a presentation tool • User test by students currently taking CprE 305 to provide feedback on the usability of the tool.

  16. Human and Financial Budgets

  17. Human and Financial (cont.)

  18. Lessons Learned • Start early on all deliverables. • Software can disappear from the labs. • Contingency plans are helpful. • Goals and milestones keep the project on track. • Communication and teamwork make for smooth sailing.

  19. Closing Summary • This software allows students to better visualize the internal processes of a micro-architecture. • Instructors are able to present course material in more flexible format.
