Core Insights - The competitive landscape of hardware-assisted verification (HAV) has significantly changed over the past decade, driven by the rapid evolution of semiconductor design and increasing complexity in system-on-chip (SoC) architectures [2] - The rise of artificial intelligence has redefined the standards that HAV must meet to keep pace with next-generation semiconductor innovations [2] Group 1: Changes in Key Deployment Aspects - The focus has shifted from compile time to runtime performance, as the most challenging tasks now involve validating extensive software workloads that can run for days or weeks [4][5] - The emphasis on multi-user support has transitioned from maximizing user concurrency to ensuring single-system critical chip pre-verification runs, driven by the emergence of single-chip AI accelerators and complex multi-chip architectures [7] - Debugging methodologies have evolved from waveform visibility to system-level visibility, utilizing software debuggers and protocol analyzers for better diagnostics of complex systems [9] Group 2: Evolution of HAV Attributes - Key attributes of HAV systems have transformed from supporting hundreds of millions of gates to tens of billions of gates, with significant improvements in emulation and prototyping frequencies [12] - The time required for bring-up has decreased from weeks or months to days, and compile times have reduced from days to hours with incremental and parallel flows [12] - The role of HAV has expanded beyond late-stage verification to become an essential pillar throughout the semiconductor design process, covering the entire lifecycle from early RTL validation to complex system integration [12]
