MENTOR Calibre 2025.4.36 is a legitimate, industry-standard electronic design automation (EDA) software tool. It is unrelated to any suspicious "CHECK"-type software and is a critical application in semiconductor manufacturing.

Mentor Calibre 2025.4.36 – Professional IC Verification Platform

Note: "Mentor" refers to Mentor Graphics, which was acquired by Siemens in 2017. The tool is now formally part of the Siemens EDA portfolio but is still widely known as "Mentor Calibre."

What It Is:

Calibre is the world's leading physical verification, design-for-manufacturing (DFM), and signoff platform for integrated circuit (IC) design.

• Purpose: To ensure a chip design is manufacturable by checking for physical and electrical rule violations before sending it to a semiconductor foundry (TSMC, Intel, Samsung, etc.).

• Core Modules:

  • Calibre DRC: Design Rule Checking (verifies geometric rules).

  • Calibre LVS: Layout vs. Schematic (verifies electrical connectivity matches the schematic).

  • Calibre xRC: Parasitic extraction (extracts electrical resistance/capacitance from layout).

  • Calibre PERC: Reliability checking (electrical rule checks for ESD, latch-up, etc.).

• Users: Physical design engineers, verification engineers, and foundries globally.

Key Aspects of Version 2025.4.36:

• Versioning: 2025.4 indicates the main 2025.4 release, and .36 is a specific build/patch for that release.

• Advanced-Node Focus: Includes support and rule decks for the latest semiconductor process nodes (2nm, 3nm, etc.).

• Performance & Capacity: Optimizations for handling massive, multi-billion transistor designs.

• Integration: Deep integration with design frameworks from Cadence and Synopsys.
