Performance Validation: Beyond AI Workloads

Comprehensive Validation Against Industry Standards

At DragonX, we've conducted extensive validation of our performance estimation tools against industry-standard simulators, particularly focusing on traditional non-AI workloads. Our recent validation study against gem5, a widely trusted simulator in the computer architecture community, demonstrates our commitment to accuracy across diverse workload types.

Validation Methodology

  • Benchmark Suite: SPEC CPU2017, PARSEC, and custom industrial workloads
  • Test Configurations: Over 20 different processor configurations
  • Architecture Types: In-order cores, varying cache hierarchies
  • Validation Metrics: IPC, cache miss rates, branch prediction accuracy

Key Results

  • 95% average accuracy compared to gem5 for IPC predictions
  • 100-1000x faster simulation speed compared to cycle-accurate simulators

Detailed Testing Process

Our validation process involves a three-phase approach:

  1. Initial calibration against open-source processors (RISC-V, ARM Cortex-A)
  2. Continuous regression testing against new architectures

This rigorous testing methodology ensures our tools maintain high accuracy while delivering the rapid evaluation capabilities needed in modern chip design workflows.

Real-World Impact

Our validated accuracy has enabled customers to:

  • Reduce design iteration cycles by 65%
  • Save millions in development costs through early-stage optimization

These results demonstrate that DragonX's tools not only match the accuracy of traditional simulators but also provide the speed and efficiency needed in modern chip design workflows.
