Simra AI is preparing to release TapeoutBench to measure how models perform across engineering work needed to reach tape-out.

Simra is building the Agents for analog and mixed-signal circuit design — not to replace engineers, but to make them dramatically more effective. Analog design remains the last manual bottleneck in semiconductor development. While digital flows were transformed by automation, analog blocks consuming 90% of design time still rely entirely on individual expertise, institutional memory, and hand-tuned iteration. Simra sits directly inside your EDA environment — Cadence Virtuoso, Synopsys Custom Compiler, Siemens Calibre — and works the way analog engineers actually work: starting from silicon-proven designs, understanding your PDKs and design history, and helping you adapt and optimize within your existing framework. We're a team of analog and mixed-signal engineers and AI researchers based in Berlin, building domain-specific intelligence for one of the hardest problems in chip design. Our system runs fully on-premise — your IP, your PDKs, and your design history never leave your infrastructure. Simra is not about autonomous chip design. It's about giving every engineer on your team the context, simulation speed, and design memory of your most experienced one.
