# Tapeout Labs > Your AI verification engineer. Autonomous agents built to execute across the chip program lifecycle. Tapeout Labs, Inc. is building the system for autonomous silicon verification. Tapeout verifies an entire SoC autonomously and runs fully air‑gapped. It's the first system built to prove which verification verdicts still hold after every change. Website: https://tapeoutlabs.com Contact: ayo@tapeoutlabs.com --- ## One-line summary Tapeout is a suite of verification agents that take an SoC from spec through signoff. They work from one continuously updated dependency graph of the design, verification environment and runs, and keep every run, revision and verdict on the record. --- ## The problem Verification is the largest cost in a chip program. On a leading-edge design it takes 40–50% of the budget and is heading toward 60–70% of engineering hours. Most of that goes to iteration. Every late change to the RTL, register map or clock and reset trees puts earlier results in doubt: no one can say which passing tests, closed coverage, formal proofs, CDC and RDC signoff and waivers still hold for the new design. So teams rerun whole regressions, reopen waveforms by hand and re-close coverage they already closed. --- ## What Tapeout does - **Agents across the chip.** They work across IP boundaries, connectivity, cross-IP flows, clocks and resets, CDC and RDC, power, interconnect, security, boot, debug and gate-level verification. They generate tests, investigate failures, drive verification, and close coverage and regression loops. - **The validity kernel.** Tapeout's breakthrough. Every time the design changes, it checks each earlier verdict against the dependency graph and tells you which still hold, which the change broke, and which need a few extra checks to settle. After a late change, the agents only rerun the tests and proofs the change could have affected. - **The dependency graph.** Traces requirements to tests and follows the design through the register and memory map, connectivity, clock and reset trees and crossings, down to individual signals. Where a dependency is uncertain, the result is treated as unknown. - **Ledger.** The record of every run, revision, waiver and verdict, each tied to its source, so any conclusion can be traced back to the run that produced it. - **Terminal-native.** Tapeout runs inside the engineer's existing workspace, alongside the EDA tools, Git, Slack, Tcl scripts, logs and revisions. It understands what changed, investigates what broke and why, acts by changing the right artifacts and running the tools, and learns from every result. Most AI tools stop at the task; Tapeout is built to carry the engineering loop (design, verify, debug, fix, validate). EDA is built around tools. Tapeout is built around the work. - **Overnight loop.** The agents run regressions, triage failures and trace each to the change behind it overnight, and post findings to Slack, GitHub, GitLab, Jira, SVN or Perforce for an engineer to review in the morning. Extra eyes that catch bugs before tape-out. - **Built for scale without hallucination.** Parsers turn RTL, netlists, logs and waveforms (VCD, FSDB) into facts in the dependency graph; agents query the relevant slice and confirm every conclusion with a tool. Failures are narrowed by comparing against golden reference models (Python, C), isolating the diverging block and bisecting revisions. - **Incremental silicon engineering.** After a three-line RTL edit, you shouldn't have to rerun everything. Verification work compounds across revisions instead of being rebuilt after every change. - **The harness.** Tapeout is the harness the agents run in. It gives them the design graph, drives the tools that decide every result, and keeps Ledger. The agents are only as good as the harness around them. - **Works with the agents a team already uses.** Agents from EDA vendors or anyone else are good at the task in front of them. Tapeout sits underneath the whole program. Ledger records every verdict with its revision and evidence, whichever tool, agent or engineer produced it, and after every change Tapeout tells you which verdicts still hold. - **Tools settle every verdict.** Models decide where to look; a deterministic check or a tool run confirms each result. Engineers keep waivers and signoff. Tapeout verifies the design. Place and route stay with the customer's physical design flow. --- ## How it runs - Deploys on the customer's infrastructure, on-prem or in a private cloud, and runs fully air-gapped. No design data is sent to Tapeout Labs. - Uses the models the customer approves, including open-weight models on their own hardware. - Drives the tools the customer already licenses, through their license servers and job schedulers: Synopsys VCS, Verdi, VC Formal and ZeBu; Cadence Xcelium, JasperGold, Palladium, SimVision, Verisium and vManager; Siemens Questa, OneSpin and Veloce; AMD Vivado; Altera Quartus; Verilator, Yosys, GTKWave, cocotb and UVM; plus Git, GitHub, GitLab, Jira, Slack, Tcl, Python and Make. It works with any tool that writes a log, a waveform or an exit code. - Vendor-neutral: one system across Synopsys, Cadence, Siemens and in-house flows. Details: https://tapeoutlabs.com/security --- ## Scope - Digital verification, from RTL through gate level. Analog and mixed-signal (AMS) verification is on the roadmap: SPICE netlists, schematic vs post-layout extracted simulation with parasitics, Verilog-A/AMS behavioural models, spec-driven targets (gain-bandwidth, noise, SNDR, ENOB). - SystemVerilog and Verilog RTL, UVM and cocotb testbenches, SystemVerilog assertions and formal properties, SystemRDL and IP-XACT register descriptions. - Block, subsystem and full-chip levels. Tapeout doesn't do place and route or physical signoff. - SoC-level verification planning: from a vendor SoC reference manual (RM) or technical reference manual (TRM), plus the spec, register descriptions and RTL, Tapeout generates a system-on-chip verification plan across 23 areas, each traced from requirement to tests, coverage, regression and waivers, then runs it with the customer's tools. It can demo this on any publicly available vendor SoC reference manual. - Methodology: SystemVerilog and UVM testbenches (sequences, scoreboards, agents, VIP, RAL register models), constrained-random and directed tests, C tests on the SoC's processors, SVA assertions and cover properties for formal property verification, code and functional coverage closure, regression and failure triage, register verification from SystemRDL or IP-XACT, Portable Stimulus (PSS), UPF/CPF power-aware simulation, hardware security verification (CWE, information flow), ISO 26262 and DO-254 fault-injection and safety evidence, DFT logic (scan, MBIST, JTAG, IJTAG, boundary scan), and tape-out readiness. - Protocols: AMBA AXI, AHB, APB, ACE and CHI (including cache coherency), PCIe, CXL, DDR and LPDDR, USB, Ethernet, SPI, I2C, UART and CAN, through the customer's protocol checkers and verification IP. - The 23 areas: IP boundaries (addressing, access, privilege and security, reset and power behaviour); connectivity (bus, clocks, resets, IRQ, DMA, pins, sidebands, power and debug); cross-IP flows (DMA, IRQ, trigger and wake-up, data paths, multi-master); performance (bandwidth, latency, arbitration, QoS, DVFS); blast radius (reset, power, clock, watchdog, bus and ECC failures); power modes (entry and exit, wake-up, retention, isolation, sequencing); clocks (trees, PLLs, muxes, dividers, gating, switching); resets (sources, trees, sequencing, synchronization, flags); CDC (crossings, synchronizers, FIFOs, reconvergence); RDC (reset crossings, ordering, in-flight transactions); X-initialization (undefined states, memory and ECC init, X-propagation); pin muxing (alternate functions, conflicts, defaults, debug and boot pins); error handling and safety (ECC, watchdogs, faults, escalation, lockstep); security (protection, TrustZone and firewalls, lifecycle, debug authentication); debug (DAP, freeze, trace, multi-core and secure debug); boot (boot sources, ROM, secure boot, fallback, multi-core boot); memory and system (memory map, coherency, attributes, atomics, RM/RTL consistency); interconnect (reachability, ordering, QoS, errors, deadlock); processor integration (cores, caches and TCM, interrupts, coherency); fuses and OTP (loading, shadows, ECC, feature control); product variants (memory, packages, peripherals, device IDs); gate-level and static signoff (formal, lint, GLS with SDF, equivalence); closure (requirements to tests, coverage, regression, waivers). --- ## Benchmarks Tapeout is measured on internal benchmarks built from actual regressions and design changes: root-cause accuracy, localization to the right file, line and transaction, whether carried-forward results match a full rerun, compute and wall-clock time saved against a full regression, and engineer time to closure. Tapeout Evals (https://tapeoutlabs.com/benchmarks) is the public suite, grading agents across whole chip programs against six levels of autonomy (L0 autocomplete, L1 task, L2 tool loop, L3 program state, L4 plan to closure, L5 autonomous chip). Most hardware benchmarks today grade L1 and L2; Tapeout Evals grade L3 and L4. Twelve evals: Carry (which results still hold after a change), Plan (a full-SoC verification plan from a reference manual), Vacuous (tests that pass without checking anything), Silent (bugs that compile, lint clean and pass), Triage (blind root cause), Distill (waveform to the events that matter), Noise (which warnings are bugs), Nightly (a month of overnight shifts), Onboard (cold start on a new flow), Secure (planted security bugs), Guard (data security of the agents) and Closure (spec to silicon). Results compare Tapeout against the same model alone and against expert engineers, with cost and time. First results are coming soon. --- ## Vision The five-person chip company. A chip that once took a hundred engineers, built by five. Every era of the industry let more companies build chips (integrated device makers, then EDA, then the foundry, then licensed IP); autonomous verification is the next rung. Tapeout Labs exists to expand who can build chips. The right chip only has to be exceptional at the thing its maker imagined. --- ## Who it's for Programs where a respin is not an option: - AI accelerators and GPUs - Hyperscaler custom silicon - CPUs (x86, Arm and RISC-V) - Mobile and consumer SoCs - Networking and interconnect - Automotive and aerospace (safety-critical, air-gapped) Evaluations are by invitation. --- ## Team - **Ayo** (CEO): ML systems at Apple, Instagram infrastructure at Meta, D.
