Migrating from ModelSim* FPGA Edition Software to Questa* – Altera FPGA Edition Software Features Key Features Run simulations across Verilog, SystemVerilog, and VHDL in a unified environment. Mixed-Language Simulation Use ready-to-go simulation libraries tailored for Altera devices—no setup needed. Precompiled Libraries Launch simulations directly from Quartus for a seamless verification flow. NativeLink Integration with Quartus® Prime Validate functionality and timing accuracy at every stage of design. Behavioral and Gate-Level Simulation Build and simulate testbenches to ensure robust functional coverage. HDL Testbench Support Analyze signals with an intuitive GUI for faster debug and visualization. Waveform Debugging and GUI Benefits Benefits Up to 2.5x/1.25 x faster Verilog/VHDL simulations compared to ModelSim*– FPGA Edition. Note: Performance measured by Siemens EDA. Performance is highly design-dependent and was measured by Siemens across 3 designs. Individual results may be higher or lower. No line limitations. Free with purchase of Quartus® Prime.

Mixed language support – Verilog/SystemVerilog, VHDL and SystemC. Questa* – Altera FPGA Starter Edition Software FAQs Questa* – Altera FPGA Edition and the Starter Edition are both tailored versions of Siemens EDA Questa* Core software, designed specifically for Altera FPGA and CPLD devices. The Starter Edition is free and ideal for entry-level use, while the full Edition supports larger, more complex designs—up to 5,000 instances (excluding instances from precompiled libraries). Both editions support Quartus Prime (Lite, Standard, and Pro), HLS Compiler, oneAPI, and DSP Builder. What is Questa* – Altera FPGA Edition and how does it differ from the Starter Edition? Both editions include gate-level libraries, behavioral simulation, HDL testbench support, and Tcl scripting. They are compatible with all Altera FPGAs and MAX® CPLDs and are supported on 64-bit Windows and Linux operating systems. What features and system support are included with Questa* – Altera FPGA Edition software? The migration is easy and largely push-button, and requires minimal to no changes in existing scripts. What are the steps to migrate from ModelSim*-FPGA edition to Questa* – Altera FPGA Edition? No. Questa* – Altera FPGA Edition software only supports (Quartus) simulation libraries, whereas Questa* Core can support any simulation libraries. The Questa* – Altera FPGA Edition software includes all the features of Siemens EDA Questa* Core, including behavioral simulation, HDL test benches, and Tcl scripting. However, features specific to Questa* Prime are not supported in the Questa* – Altera FPGA Edition software. Questa* – Altera FPGA Edition software is slower than the Siemens EDA Questa* Core and Questa* Prime software. Contact your local Siemens EDA sales office to upgrade your Questa* – Altera FPGA Edition software to Questa* Core or Questa* Prime simulator. Is the Questa* – Altera FPGA Edition software the same as the Siemens EDA Questa* Core software?
