What Concept Engineering does

Concept Engineering GmbH is a Freiburg, Germany-based software firm founded in 1990 by Gerhard Angst and Lothar Linhard that develops electronic system visualization and debugging technology. The company operates two product families: standalone design debug tools (StarVision PRO for mixed-signal/SoC debugging, RTLvision PRO for RTL debugging, GateVision PRO for gate-level debugging, and SpiceVision PRO for transistor-level debugging) and embeddable visualization engines (Nlview, T-engine, S-engine, E-engine, and the EEvision platform) that license into third-party EDA and CAD tools. Its proprietary technology stack centers on automatic schematic generation with circuit pattern recognition, current-flow analysis, and intelligent rendering across transistor, gate, RTL, and system design levels, with widget variants for Tcl/Tk, Java, MFC, Qt, Perl, plus a JavaScript/WebAssembly deployment (NlviewJS).

The firm monetizes through one-time software licenses to end-user semiconductor, automotive, and aerospace customers and through OEM licensing royalties from more than 40 EDA/CAD partners (including Cadence, Real Intent, Aldec, Calypto, Oasys, Tabula, and Verific) whose tools collectively embed Concept visualization engines across more than 100,000 deployed EDA seats. Distribution combines direct enterprise sales, regional sales representatives in China, Japan, Korea, France, and Italy, OEM partnership channels, and free online evaluations via FLEXnet licensing. The company serves three primary verticals: semiconductor and EDA companies, automotive OEMs and suppliers (including service-center workflows via the E-engine), and aerospace (notably NASA/JPL for Mars and Europa missions).

Concept Engineering was acquired by Altair Engineering (Nasdaq: ALTR) in June 2022 and now operates as a subsidiary. Prior to the acquisition, the firm reported 17 consecutive years of profitability as of 2010 and maintained a stable headcount of 11-50 employees, reflecting a niche specialist operating model rather than a high-growth SaaS profile.

Core offering

Concept Engineering develops and sells electronic system visualization and debugging software used to debug complex semiconductor designs, accelerate automotive electrical system development and service, and supply OEM visualization engines to EDA/CAD tool developers. Its portfolio includes standalone debug tools (StarVision PRO, RTLvision PRO, GateVision PRO, SpiceVision PRO, SGvision PRO), embeddable visualization engines (Nlview family, T-engine, S-engine, E-engine), and the EEvision platform for on-board electrical system exploration.

Product overview

Concept Engineering is an electronic system visualization software provider offering a comprehensive portfolio of design debug tools and visualization engines for the EDA, automotive, and aerospace markets. The product portfolio consists of two main categories: (1) Standalone Design Debug Tools including StarVision PRO (mixed-signal/SoC debugging), RTLvision PRO (RTL debugging), GateVision PRO (gate-level debugging), and SpiceVision PRO (transistor-level debugging); and (2) Visualization Engines for OEM integration including Nlview (schematic viewing), T-engine (transistor-level), S-engine (system-level), and E-engine (automotive electrical). These engines are embedded into third-party EDA and CAD tools through an established OEM partnership program. Additionally, EEvision serves as a visualization platform specifically designed for automotive and aerospace electrical system exploration, featuring Google-like search capabilities for schematic navigation.

Broad incumbents

• Siemens EDA (Mentor Graphics): Siemens's EDA division competes in chip and PCB/system design with tools such as Calibre, Tessent, and Capital for electrical/wire-harness design. Concept competes or partners along the same debugging and electrical-architecture workflows, particularly in automotive and aerospace.
• Cadence Design Systems: Major EDA incumbent and the same partner with which Concept is a member of the Cadence Connections Program. Cadence competes in the same design/debug workflow space and Concept's tools are explicitly interop-compatible with Cadence Virtuoso/Spectre netlists.
• Synopsys: One of the 'big three' EDA vendors offering broad chip design and verification suites. Many Concept OEM partners and end customers sit on Synopsys platforms, making Synopsys a broad incumbent whose roadmap choices directly affect Concept's addressable integration surface.
• Altair Engineering: Parent company since the June 2022 acquisition and a broader simulation/EDA-adjacent platform (inspire, SimSolid, FEKO, Electronic System Design). Altair sells into many of the same automotive and aerospace customers and now bundles Concept's visualization into its portfolio.
• Dassault Systèmes (3DEXPERIENCE / CATIA Electrical): PLM/CAD major providing electrical and systems engineering tools used by automotive and aerospace OEMs. Concept's EEvision competes in adjacent workflows around electrical architecture visualization, MBSE integration, and harness/service schematics.

Direct peers

• Zuken: Provider of CR-8000 and E3.series electrical and harness design tools for automotive, aerospace, and industrial markets. Concept's EEvision and E-engine directly overlap with Zuken's electrical-architecture visualization and service tooling.
• Real Intent: Provider of RTL and gate-level signoff/analysis tools (Meridian, Ascent). Real Intent has a multi-year OEM license embedding Concept's RTLvision debugger, making it both partner and competing supplier of chip debugging analytics to similar semiconductor customers.
• Aldec: EDA vendor for FPGA/ASIC verification (Active-HDL, Riviera-PRO) and CDC analysis (ALINT-PRO-CDC). Aldec licenses Concept's Nlview as its visualization engine, making it simultaneously a customer and a direct peer serving overlapping IC debug users.
• Verific Design Automation: Supplier of netlist database and HDL parsing components (SystemVerilog, VHDL) used by EDA tool developers. Concept integrates with Verific's netlist database, and Verific sits in the same EDA component-supply layer serving many of the same OEM partners.

Emerging players

• Vtool Smart Verification: Verification-focused EDA company offering the Cogita visual verification platform. Vtool partnered with Concept in 2022 to combine Cogita with StarVision PRO and RTLvision PRO, addressing the same ASIC/SoC debug workflow with overlapping technology.
