Altair® DSim™

On-Demand Semiconductor Functional Verification

Altair® DSim™ is a complete digital simulator designed for semiconductor electronic functional verification. Supporting both SystemVerilog and very high-speed integrated circuit hardware description language (VHDL), it’s ideally suited for application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs), offering a robust solution for advanced design needs.

Available on-prem or through our transformative simulation-as-a-service (SaaS) model, DSim makes functional simulation for complex semiconductors accessible to all, enabling seamless transitions from desktop to cloud. Experience the power of concurrent, scalable simulations and flexible licensing that drastically cut both time and cost compared to traditional design methods.

Why DSim?

HPC center with overlayed computer text representing systemverilog code for multiple electronic functional simulations.

Mixed Language Digital Simulator

DSim for semiconductor electronic functional verification supports VHDL, Verilog, and SystemVerilog languages—all within the same design. The solution is perfectly suited for ASIC and FPGA designs.

Scalable, Cost-Effective Simulation

Seamlessly transition local simulations to the cloud and run simulations concurrently and at scale, significantly reducing time and cost.

Key Features

SystemVerilog and VHDL Simulator

Perform semiconductor functional verification with full SystemVerilog, universal verification methodology (UVM), VHDL, and mixed-language simulation.

Easy Simulation and Job Orchestration

DSim’s easy-to-use environment lets you run your first simulation in minutes. With just one click, submit your local job to the cloud or rapidly create a job file with all tasks and dependencies for more complex test suites.

True SaaS

SaaS convenience means you only need to focus on DSim's functionality, eliminating hardware management – all compute resources are fully managed for you.

Scalable Simulation

Easily scale your simulations. Run thousands of simulations simultaneously for your regression testing, shortening your time to market.

Code Coverage

Gauge your testbench completeness with block, expression, and toggle coverage.

Seamless C and C++ Integration

Easily integrate C/C++ models in source or object form using direct programming interface (DPI), programming language interface (PLI), and verification procedural interface (VPI).

Run-Time Performance

DSim's compiled-code architecture and code-structure optimization deliver efficient run-time performance.

IP Security Support

IEEE 1735 support for industry-standard encryption ensures your own IP is protected and handles encrypted design and verification IP (VIP) from third parties.

Import Compatibility

Use command-line switches to relax semantic checks and ensure compatibility with code developed for other simulators.
