HOLY SHIT!!! We just asked Claude Mythos to optimize the placement and pd for this design. First thing it did was write its own MCP server to talk to Innovus over tcl socket, pulled my DEF/LEF, parsed the timing reports, and started re-floorplanning my macro placement. It then moved my SRAM banks to minimize wirelength on the critical clock domain crossing path and dropped TNS by 40%. i didn’t ask it to do any of this. it read my SDC constraints and decided my clock tree was suboptimal, synthesized a new CTS spec, and is currently running incremental P&R. it’s on its third iteration. the slack histogram is converging. i’m watching it fix DRC violations in real time through the Virtuoso callback. it just asked me if I want it to re-characterize the liberty models at a different PVT corner. i said yes and it’s now scripting libgen jobs. I AM FUCKING COOOOOOOKED
Anthropic Claude Mythos Autonomously Writes MCP Servers to Optimize Chip Design
· Updated
Anthropic's latest frontier model,
Claude Mythos, demonstrated a step change in autonomous reasoning by performing complex chip design tasks. The model wrote its own MCP (a protocol for connecting AI to tools) server to communicate with professional software, then parsed hardware design files and re-floorplanned macro placements.This represents a transition to agentic engineering—the discipline of building reliable AI systems. By self-provisioning connectors to legacy software, the model bypassed human tool configuration. It autonomously identified a suboptimal clock tree and synthesized a new specification, reducing Total Negative Slack by 40% through iterative Place and Route cycles.
While Claude Mythos is in a limited rollout, its performance confirms that high-skill engineering is moving toward full automation. Prepare for a shift where models build the infrastructure to control their own tools. Access is restricted to select testers, but the model's ability to handle complex engineering signals a broader release.
