Silogy
On-prem AI verification engineer that root-causes failing chip tests from RTL, logs, and waveforms.
What is Silogy?
Silogy makes Viv, an AI verification engineer for chip design that automatically debugs failing tests by reading code, log files, waveforms, and a continuously updated knowledge base. It plugs into existing CI/CD via a CLI, runs on-premise so no chip-design data leaves customer servers, and uses bring-your-own-key LLM access. The company claims test-debug times drop by up to 90%.
Coding agents and AI developer tools for writing, reviewing, debugging, and shipping software.

Use cases to evaluate
Root-cause SystemVerilog/UVM test failures from waveforms automatically
Integrate AI triage into existing simulator CI/CD via CLI
Run AI verification fully on-prem to keep RTL off external servers
Use your own LLM API key (OpenAI, Anthropic, Azure) for compliance
Fit to evaluate
ASIC and SoC verification teams
Semiconductor companies with strict IP-protection policies
Chip design groups already running CI for simulation
Hardware startups scaling verification without scaling headcount
Business fit
Right for you if you're a semiconductor or ASIC team where verification engineers spend significant time triaging UVM/SystemVerilog test failures and your security policy forbids sending RTL or waveforms to a cloud LLM. Skip if you're not doing hardware verification - this is not a general-purpose code assistant. The on-prem + BYOK model is the differentiator versus cloud verification copilots, and the 7-day free trial lets a verification team validate Viv on real failing tests before committing.
How to evaluate Silogy
Use this category when software delivery speed, code review, or developer leverage is a business constraint.
Confirm the exact workflow
Map Silogy to one concrete workflow first, such as root-cause systemverilog/uvm test failures from waveforms automatically. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Test with your actual repository and review diff quality.
Compare practical alternatives
Shortlist Silogy against Codex, Claude Code, Cursor so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
Validate cost and rollout effort
Also confirm implementation time, support needs, and whether the technical setup matches your team.
