The modern version of the NCsim family, called Incisive Enterprise Simulator, includes Verilog, VHDL, and SystemVerilog support and boasts some unique features (such as support for the e verification language) and a fast SystemC simulation kernel. In response to competition from faster simulators, Cadence developed its own compiled-language simulator, NC-Verilog. As one of the 'big 3' simulators Modelsim/SE is qualified for ASIC (validation) sign-off at nearly all semiconductor fabs.Ĭadence initially acquired Gateway Design, thereby acquiring Verilog-XL.

However, as the Verilog component of Modelsim is neither the fastest nor most fully featured simulator on the market, competition from Synopsys and Cadence, led to a continual decrease in Modelsim popularity. The original Modeltech (VHDL) simulator already commanded a loyal userbase, and attracted many new users with the first mixed-language simulator capable of simulating VHDL and Verilog design entities together. Though considered one of the least expensive simulators, ISE Simulator (ISim) provides support for mixed-mode language simulation including, but not limited to, simulation of designs targeted for Xilinx's FPGAs and CPLDs. Xilinx's simulator comes bundled with the ISE Design Suite. When simulated in compiled mode its performance rivals that of any other simulator. CVC has the ability to simulate in either interpreted or compiled mode. While ActiveHDL is a low-cost product, Aldec also offers a more expensive, higher-performance simulator called "Riviera."ĬVC is a high performance Verilog HDL compiled simulator. Aldec licenses Active-HDL to FPGA-vendors, and the underlying engine can be found in the design-suites of those vendors. For designs targeting high-capacity FPGA, a standalone simulator is recommended, as the OEM-version may lack the capacity or speed to effectively handle large designs.īelow is a list of simulators that implement the Verilog hardware description language:Ĭommercial Simulators List of Verilog Simulators in Alphabetical Order by NameĪ simulator with complete design environment well suited for FPGA-applications. The bundled simulator is taken from an entry-level or low-capacity edition, and bundled with the FPGA vendor's device libraries.
In fact, most vendors include an OEM version of a third-party HDL simulator in their design suite. Pricing is not published publicly, but all three vendors are known to charge $25,000-$100,000 USD per seat, 1-year time-based license.įPGA vendors do not require expensive enterprise simulators for their design flow. Although the customer is not required to perform any signoff checking, the tremendous cost of a wafer order has generally ensured thorough design-validation on the part of the customer.) The three major signoff-grade simulators include Cadence Incisive Enterprise Simulator, Mentor Modelsim/SE, and Synopsys VCS. ( Semiconductor foundries stipulate the usage of tools chosen from an approved list, in order for the customer's design to receive signoff status. The last point is critical for the ASIC tapeout process, when a design-database is released to manufacturing.

Additionally, limited-functionality editions of the Aldec and Modelsim simulator are downloadable free of charge, from their respective OEM partners (Actel, Altera, Lattice Semiconductor, Xilinx, etc.) For those desiring open-source software, there is Icarus Verilog, among others.īeyond the desktop level, enterprise-level simulators offer faster simulation runtime, more robust support for mixed-language ( VHDL and Verilog) simulation, and most importantly, are validated for timing-accurate (SDF-annotated) gate-level simulation. The suites bundle the simulator engine with a complete development environment: text editor, waveform viewer, and RTL-level browser.

For desktop/personal use, Aldec, Mentor, LogicSim, SynaptiCAD, and others offer reasonably priced (<$5000 USD) tool-suites for the Windows 2000/XP platform.
Today, Verilog simulators are available from many vendors, at all price points.

Verilog simulation software has come a long way since its early origin as a single proprietary product offered by one company. Template:wikipedia list Verilog simulators are software packages that emulate the Verilog hardware description language.
