Siemens Questa 2026.1: Advanced Functional Verification Platform

Questa 2026.1 (Version 26.1) is the latest release of Siemens' industry-leading functional verification platform, encompassing both the Questa FPGA Pro Edition for FPGA designers and the Questa One Agentic Toolkit for advanced IC verification . This version introduces agentic AI workflows alongside core functional and security updates .

Key New Features

Questa One Agentic Toolkit (Agentic AI)

The major highlight for the ASIC/SoC verification flow is the introduction of the Questa One Agentic Toolkit, which brings domain-scoped agentic AI workflows to the Questa One smart verification software portfolio . Announced in February 2026 and currently available via early access, it transforms verification from isolated tool interactions into intelligent, multi-step autonomous processes .

The toolkit includes purpose-built agents that operate with configurable human oversight :

• RTL Code Agent: Generates synthesizable RTL code from natural language descriptions and checks for coding violations .

• Lint Agent: Configures and runs lint analysis, offering AI-powered fixes or waivers .

• CDC Agent: Configures clock domain crossing verification and provides fine-tuning suggestions .

• Verification Planning Agent: Analyzes design specifications to automatically generate comprehensive verification plans .

• Debug Agent: Accelerates root cause analysis by correlating waveforms, assertions, and log files .

The toolkit is framework-agnostic, working with GitHub Copilot, Claude Code, Cursor, and Siemens' own Fuse EDA AI system, while leveraging NVIDIA Llama Nemotron and NVIDIA NIM . Siemens uniquely combines this agentic AI with its own verification engine expertise, maintaining deep integration with tools like Tessent (DFT) and Veloce CS (hardware-assisted verification) .

Questa FPGA Pro Edition Updates (Version 26.1)

For FPGA designers, Questa 26.1 provides the latest functional and security updates . Users should keep their software up-to-date to improve security, with additional updates planned .

Core Verification Capabilities (General)

Questas core capabilities include Questa One Sim for advanced simulation (with UVVM constrained randomization, metastability injection, and automated unreachability analysis) , Questa One SFV for formal verification (including AI-assisted property generation) , Questa CDC for clock domain crossing verification with power-aware analysis , and Questa Check Register/Connect for automated SoC register and connection verification .
