It is a compiled-language simulator that supports mixed language simulation with Verilog, SystemVerilog, VHDL and SystemC language. It supports standard debugging tool such as step through code, breakpoints, cross-probing, value probes, call stack and local variable Window.
Verilator is a software programming tool which converts the hardware description language Verilog to a cycle-accurate behavioral model in the programming languages C++ or SystemC. The generated models are cycle-accurate and 2-state; as a consequence, the models typically offer higher performance than the more widely used event-driven simulators ...
Originally, Verilog was only intended to describe and allow simulation; the automated synthesis of subsets of the language to physically realizable structures (gates etc.) was developed after the language had achieved widespread usage. Verilog is a portmanteau of the words "verification" and "logic". [5]
Released under the GNU General Public License, Icarus Verilog is free software, an alternative to proprietary software like Cadence's Verilog-XL. As of release 0.9, Icarus is composed of a Verilog compiler (including a Verilog preprocessor) with support for plug-in backends, and a virtual machine that simulates the design.
In preparation for synthesis, the HDL description is subject to an array of automated checkers. The checkers report deviations from standardized code guidelines, identify potential ambiguous code constructs before they can cause misinterpretation, and check for common logical coding errors, such as floating ports or shorted outputs. This ...
The synthesis tool also performs logic optimization. At the register-transfer level, some types of circuits can be recognized. If there is a cyclic path of logic from a register's output to its input (or from a set of registers outputs to its inputs), the circuit is called a state machine or can be said to be sequential logic .
ModelSim is a multi-language environment by Siemens [1] (previously developed by Mentor Graphics, [2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. [3] [2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, [4] Xilinx ISE or Xilinx ...
