LogicLance is an AI-powered ASIC flow automation platform — unifying synthesis, place-and-route, timing signoff, and verification into a single intelligent RTL-to-GDSII pipeline. Native adapters for Cadence, Synopsys, and OpenROAD. An AI/LLM engine that reads the logs, explains the timing failures, and monitors flow health. Built for the demands of advanced-node semiconductor design.
LogicLance is the tooling SandLogic built to design its own silicon. Running the ASIC flow for the Krsna SoC and the ExSLerate IP family meant orchestrating Cadence, Synopsys, and open-source tools across synthesis, place-and-route, and signoff — and the existing flow managers weren't good enough. So we built our own. It was good enough to patent. Now it's a product.
Advanced-node ASIC design has outgrown the scripts that manage it. Five structural problems define the crisis — and every one is an orchestration problem, not a chip-design problem.
ASIC teams juggle Cadence, Synopsys, OpenROAD and more — each with its own scripts, licenses, and failure modes. Engineers spend 60%+ of their time on flow management instead of design innovation, and a large share of project time on team and environment setup before chip design even begins.
Timing violations, DRC errors, and convergence failures buried in thousands of log lines. No intelligent triage. No root-cause analysis. Weeks lost to manual log inspection with no guarantee of resolution, and no timely notification on errors or flow completion.
Without intelligent orchestration, ASIC teams face challenges in timing closure, log analysis, license management, and multi-tool integration. Traditional flows lack automation, centralized monitoring, and the AI-assisted debugging modern chip design needs.
Most traditional flows lack centralized dashboards, real-time monitoring, flow health scoring, progress tracking, and failure prediction. Managers and engineers cannot easily answer: which stage failed? why did runtime increase? which job is blocked?
As projects evolve — RTL changes, more corners, different nodes, more verification iterations, more signoff checks — traditional scripts become difficult to maintain. Flows turn fragile, unscalable, and engineer-dependent.
LogicLance is positioned as an operating system for ASIC design — not a flow generator. Five capabilities cover the full lifecycle from RTL to tapeout.
A centralized orchestration engine that unifies Cadence, Synopsys, and open-source EDA flows into a single automated platform. Engineers launch, monitor, and manage complete RTL-to-GDSII flows without manually handling scripts, environments, or tool integration.
AI-powered log analysis and intelligent debugging automatically identify timing violations, DRC/LVS failures, convergence issues, and infrastructure errors. Instead of inspecting thousands of log lines, engineers receive summarized root-cause insights, failure predictions, and recommended fixes.
LogicLance accelerates timing closure through automated flow monitoring, constraint analysis, and intelligent optimization assistance. The platform continuously tracks setup/hold violations, congestion hotspots, and design-constraint issues — reducing manual iteration cycles.
Centralized dashboards with real-time flow monitoring, flow-health scoring, progress tracking, runtime analytics, and failure prediction. Engineers and managers gain complete visibility across every stage of the ASIC flow, enabling faster issue detection.
LogicLance standardizes ASIC workflows using version-controlled automation pipelines, reusable flow templates, and centralized configuration management. This reduces dependency on tribal knowledge, improves onboarding, and enables scalable flow execution.
LogicLance integrates natively with the world's leading commercial and open-source EDA platforms through battle-tested adapters. The same orchestrated flow runs across vendor toolchains — no per-project glue scripts.

Where traditional flows leave engineers grepping through thousands of log lines, LogicLance puts an AI/LLM engine between the tools and the team — turning raw EDA output into root-cause insight.
Parses millions of log lines in seconds. Identifies root-cause errors, flags anomalies, and surfaces critical warnings with severity ranking.
Translates complex timing reports into plain-language summaries. Auto-recommends constraint tweaks, clock adjustments, and buffer insertions.
Continuously scores the health of every active flow stage. Predicts convergence risk and proactively alerts engineers before tape-out blockers emerge.
A chat-native interface for asking "why did my place-and-route fail?" or "what is the fastest path to timing closure on this clock domain?" — answered with design-specific context.
Every stage is orchestrated automatically — tool launch, job scheduling, artifact handoff, and failure recovery. Engineers define the intent; LogicLance executes it.
Traditional flows make the engineer the orchestrator — launching tools, checking out licenses, moving artifacts between stages, and babysitting failures. LogicLance inverts that. The engineer specifies what the flow should achieve; the platform handles how it runs — across vendors, across stages, with intelligence at every step.
The difference between traditional manual flows and LogicLance, capability by capability.
| Capability | Traditional flow | LogicLance |
|---|---|---|
| Flow management | Manual shell scripts, per-engineer configs | Unified orchestration engine, version-controlled flows |
| Debugging | Manual log grep, days of investigation | AI triage in seconds, root-cause analysis |
| Multi-tool integration | Custom glue scripts per project | Native adapters for all major EDA vendors |
| Monitoring | None — check logs manually | Real-time flow-health dashboard with alerts |
| Scalability | Manual job management | Auto-scheduling, multi-terminal parallel runs |
| Security | Shared accounts, no audit trail | RBAC, isolation, full audit log |
| Notifications | None | Alerts on errors, warnings, completion — with summarised logs |
| Onboarding | Months of tribal knowledge transfer | GUI + AI assistant guides new engineers from day one |
