TapeCheck
Self-serve RTL verification for hardware startups, FPGA developers, and EE students — upload RTL plus spec, get a coverage-grounded testbench environment with named behavior bins, interface-mismatch detection, and a pre-tapeout report.
Verification engineers at fabless hardware startups and advanced FPGA developers
- Spec-grounded testbench generation with coverage bins mapped to named behaviors
- Interface-mismatch detection across multi-module hierarchies
- Coverage report with diagnosable gaps and suggested targeted remedies
- Free tier for students and hobbyists, paid tier for pre-tapeout startups
Trending paper demonstrates agentic RTL verification hitting 98%+ line and 97%+ branch coverage without human intervention; the same ideas can be packaged for teams that can't afford Synopsys VCS or Cadence enterprise seats.
GoGoTB paper documents that 'functional verification dominates integrated IC front-end engineering effort' and UVM environment assembly takes 'weeks of specialized effort per design' — pain is real and broadly acknowledged, but the target niche (verification engineers at fabless startups + advanced FPGA devs) is narrow.GoGoTB: Agentic RTL Verification with Specification-Grounded Coverage Closure ↗RTL Testing and Verification overview ↗
Crowded space: open-source cocotb+Verilator+VUnit cover most self-serve needs for free; rtl-buddy already bundles Verilator/VCS/cocotb flows; commercial entrants MosChip (agentic RTL), Axiomise (formal), and academic systems GoGoTB (Tencent/PKU) and UVM2 all attack the same problem from different angles.cocotb | Python verification framework ↗rtl-buddy: Python CLI for Verilog and SystemVerilog ↗Accelerating RTL Design with Agentic AI: MosChip multi-agent approach ↗Axiomise Partners With Bluespec to Verify RISC-V Cores ↗
Synopsys/Cadence enterprise seats command six-figure prices (Vendr marketplace tracks these), giving clear pricing reference, but Verilator and cocotb are free/BSD and already deliver self-serve UVM-style testbenches — compressing willingness-to-pay for the target cash-sensitive audience of startups, FPGA hobbyists, and EE students.Synopsys Software Pricing & Plans 2026 (Vendr) ↗VCS Functional Verification Solution — Synopsys ↗
Functional verification is a permanent, multi-decade requirement for any taped-out silicon and a respin costs orders of magnitude more than pre-silicon bugs — demand will outlast any current AI vendor, though the specific 'agentic coverage closure' category will likely consolidate.GoGoTB: Agentic RTL Verification with Specification-Grounded Coverage Closure ↗
Doable but non-trivial: must integrate a real simulator (Verilator/VCS), a coverage database (URG/Icarus), and an LLM agent loop with reliable tool-call discipline; rtl-buddy already shows the integration scaffolding exists, but achieving trustworthy specification-grounded coverage (the hard part) requires deep EDA expertise and validated benchmarks.rtl-buddy: Python CLI for Verilog and SystemVerilog ↗GoGoTB: Agentic RTL Verification with Specification-Grounded Coverage Closure ↗
