The Verilog Procedural Interface (VPI), originally known as PLI 2.0, is an interface primarily intended for the C programming language. It allows behavioral Verilog code to invoke C functions, and C functions to invoke standard Verilog system tasks.
Similarly, functions implemented in SystemVerilog can be called from Foreign language (C/C++ or System C); such functions are called Export functions. DPIs allow transfer of data between two domains through function arguments and return.
Classes can be parameterized by type, providing the basic function of C++ templates. However, template specialization and function templates are not supported. SystemVerilog's polymorphism features are similar to those of C++: the programmer may specifically write a virtual function to have a
File I/O has been improved by several new system tasks. And finally, a few syntax additions were introduced to improve code readability (e.g. always @*, named parameter override, C-style function/task/module header declaration). Verilog-2001 is the version of Verilog supported by the majority of commercial EDA software packages.
System Verilog is the first major HDL to offer object orientation and garbage collection. Using the proper subset of hardware description language, a program called a synthesizer, or logic synthesis tool , can infer hardware logic operations from the language statements and produce an equivalent netlist of generic hardware primitives [ jargon ...
Verilog-AMS is a derivative of the Verilog hardware description language that includes Analog and Mixed-Signal extensions (AMS) in order to define the behavior of analog and mixed-signal systems. It extends the event-based simulator loops of Verilog/ SystemVerilog / VHDL , by a continuous-time simulator, which solves the differential equations ...
The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e verification language developed by Verisity Design in 2001.
The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off. 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.
