System verilog is far superior then\r\nthe verilog because of it ability too perform the constrained random stimuli, use OOP feature in testbench\r\n\r\n## WHAT IS VERILATOR\r\nVerilator is a tool that compiles Verilog and SystemVerilog sources to highly optimized (and optionally multithreaded) cycle-accurate C++ or SystemC code. \r\nThe converted modules can be instantiated and used in a C++ or a SystemC testbench, for verification and/or modelling purposes.\r\n\r\n## WHY WE USE VERILATOR\r\nVerilator is essentially a Verilog/SystemVerilog simulator. It’s commercial-grade, super fast, free and open source, but it is not a direct replacement \r\nfor Modelsim, Questa Sim, Synopsys VCS, Vivado Xsim, and other event-based simulators. Verilator is a cycle-based simulator, which means it does not \r\nevaluate time within a single clock cycle, and does not simulate exact circuit timing. Instead, the circuit state is typically evaluated once per clock-cycle, \r\nso any intra-period glitches cannot be observed, and timed signal delays are not supported. This has both benefits and drawbacks when comparing Verilator to other simulators.\r\n\r\n# INSTALLATION PROCESS\r\n\r\n```\r\nsudo apt update\r\n\r\nsudo apt install verilator\r\n\r\nverilator --version\r\n```\r\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmuhammadtalhasami%2Fsv_verilator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmuhammadtalhasami%2Fsv_verilator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmuhammadtalhasami%2Fsv_verilator/lists"}
