Built for curious engineers.
We build focused, connected tools for the VLSI physical design flow — so your team can move from schematic to signoff without stitching together five different toolchains.
Connected tools for the physical design flow
Most physical design flows are stitched together from tools that don't talk to each other — different formats, different viewers, different assumptions at every handoff. We started from a different question: what if one connected set of tools covered the whole flow, from schematic capture to SoC signoff?
That question shaped every tool we build — KTool, PnrViewer, SocChecker, CTSMeshViewer, StaAgent, and SocPartitionFeedthroughOptimizer are each built for one stage, and built to hand off cleanly to the next.
Principles behind every tool.
The same three commitments show up in every tool we ship, from the tools available today to what's still in development.
Built for the real flow
Every tool is scoped around an actual stage of the physical design flow — not a generic feature list, but the thing you need at that point in the schedule.
Clean handoffs
Each tool is designed to consume what the previous stage produced and hand off cleanly to the next — from schematic through to signoff.
Built with design teams, for design teams
Every feature is shaped by watching real physical design teams hit friction, then designing the tool so that friction doesn't happen again.
From one tool to a full flow.
VLSI Tools started with schematic capture. The set of tools grew stage by stage from there.
KTool, the first tool
Built to answer one question: what would schematic capture look like if it were fast, keyboard-driven, and validated nets live?
PnrViewer, SocChecker & CTSMeshViewer take shape
The natural next stages — visualizing physical implementation, checking SoC-level connectivity, and tracking the clock tree through CTS.
StaAgent closes the timing loop
An automated agent for static timing analysis, so signoff-critical paths surface early instead of at the last corner run.
SocPartitionFeedthroughOptimizer, in development
We're building out feedthrough optimization for abutted-block partitioning — the final stage that ties the flow together ahead of tapeout.
