UVM 1.2 & SystemVerilog Assertion Engineering

SOC Verification & Functional Sign-Off

Production-grade SystemVerilog/UVM constrained-random testbenches, assertions (SVA), coverage closure, and regression management for complex ASICs and SOCs. We eliminate first-silicon respins through rigorous corner-case stress verification.

The Complete SOC Verification Stack

From initial verification planning and VIP integration to tape-out sign-off, our verification architects guarantee silicon functional integrity.

UVM Testbench Architecture

Structuring scalable UVM environments with modular UVM agents (driver, sequencer, monitor), reference prediction models, and TLM analysis ports.

  • Multi-channel active & passive UVM agents
  • Cycle-accurate C/SystemC reference scoreboards
  • Reusable virtual sequencer hierarchies

Constrained-Random Verification (CRV)

Generating weighted, pseudo-random stimuli to expose unexpected race conditions, FIFO overflows, bus contention, and arbitration deadlock corners.

  • Weighted distribution & soft/hard constraints
  • Boundary condition & back-to-back burst stress
  • Multi-master crossbar arbitration stress testing

SystemVerilog Assertions (SVA)

Concurrent and temporal property checks embedding protocol requirements into the RTL to catch functional violations at the exact clock cycle of failure.

  • Handshake & latency window temporal checks
  • Formal verification assertion integration
  • Immediate assertion safety traps

Coverage-Driven Closure (CDV)

Systematic functional covergroups, cross-coverage bins, and code coverage (statement, branch, condition, toggle, and FSM transition) sign-off.

  • 100% covergroup & cross-coverage closure
  • Code coverage hole analysis & exclusion waivers
  • Unified coverage metrics databases (UCDB)

Protocol Verification IP (VIP) Integration

Integrating and customizing standard protocol VIPs for on-chip and off-chip interfaces including AMBA AXI4/AHB/APB, PCIe Gen 4/5, Ethernet, and DDR4/5.

  • AXI4 interleaving & out-of-order verification
  • Memory controller burst protocol checking
  • High-speed serial protocol compliance checks

Automated Regressions & CI/CD Triage

Cloud and server-farm regression management, multi-seed batch dispatching, automated log parsing, and failure triage dashboards.

  • Automated seed farming with regression scoring
  • Failure clustering & waveform artifact capture
  • CI/CD regression gating for Git commit pipelines

The SOC Verification Sign-Off Pipeline

Our battle-tested roadmap for taking ASICs from architectural micro-specs to 100% verified tape-out sign-off.

Stage 01
vPlan Creation
Extracting testable features, corner scenarios, assertions, and coverage goals.
Stage 02
TB Architecture
Building UVM agents, sequencers, drivers, monitors, and scoreboard harnesses.
Stage 03
Smoke & Directed
Basic register sanity tests, reset sequence validation, and datapath smoke runs.
Stage 04
Random Regressions
Multi-seed constrained-random runs to hunt boundary bugs and race conditions.
Stage 05
Coverage Closure
Analyzing unhit bins, crafting targeted sequences, and eliminating coverage holes.
Stage 06
Tape-Out Sign-Off
Zero known bugs, 100% functional/code coverage sign-off, and netlist verification.
