system verilog simulator

Due to a strategic decision to support SystemVerilog (instead of SystemC), and the timely acquisition of Superlog (the forerunner to SystemVerilog), Synopsys/VCS was the first SystemVerilog simulator in the market. This simulator used to be proprietary, but has recently become GPL open-source. After its acquisition by Cadence Design Systems, Verilog-XL changed very little over the years, retaining an interpreted language engine, and freezing language-support at Verilog-1995. The extensions version of Verilog’s literal values is the system Verilog’s literal values. Today, VCS provides comprehensive support for all functional verification methodologies and languages (including VHDL, Verilog, SystemVerilog, Verilog AMS, SystemC, and C/C++), and advanced simulation technologies including native low power, x-propagation, unreachability analysis, and fine-grained parallelism. The Verilog code is divided into multiple processes and threads and may be evaluated at different times in the course of a simulation, which will be touched upon later. SystemVerilog simulator used on the Metrics cloud platform. What is a SystemVerilog string ? With Silvaco's acquisition of SimuCad, Silos is part of the Silvaco EDA tool suite. A string variable does not represent a string in the same way as a string literal. In response to competition from faster simulators, Cadence developed its own compiled-language simulator, NC-Verilog. FPGA vendors do not require expensive enterprise simulators for their design flow. Cadence initially acquired Gateway Design, thereby acquiring Verilog-XL.
