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.
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.
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 ...
SystemVerilog for register-transfer level (RTL) design is an extension of Verilog-2005; all features of that language are available in SystemVerilog. Therefore, Verilog is a subset of SystemVerilog. SystemVerilog for verification uses extensive object-oriented programming techniques and is more closely related to Java than Verilog. These ...
Verilog-A was an all-analog subset of Verilog-AMS that was the project's first phase. There was considerable delay between the first Verilog-A language reference manual and the full Verilog-AMS , and in that time Verilog moved to the IEEE, leaving Verilog-AMS behind at Accellera .
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.
Verilog-A 2.0 LRM-compliant behavioral models and structural netlists; DSPF/SPEF parasitic formats; S-parameter data files in Touchstone, CITI-file, and Spectre formats; SST2, PSF, PSF XL, and FSDB waveform formats; Digital vector (VEC), Verilog-Value Change Dump (VCD), Extended Verilog-Value Change Dump (EVCD), and digital stimulus
This is a list of file formats used by computers, organized by type. Filename extension is usually noted in parentheses if they differ from the file format 's name or abbreviation. Many operating systems do not limit filenames to one extension shorter than 4 characters, as was common with some operating systems that supported the File ...
