In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs). A hardware description language enables a precise, formal ...
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 was later submitted to IEEE and became IEEE Standard 1364-1995, commonly referred to as Verilog-95. In the same time frame Cadence initiated the creation of Verilog-A to put standards support behind its analog simulator Spectre. Verilog-A was never intended to be a standalone language and is a subset of Verilog-AMS which encompassed ...
A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be repeatedly programmed after manufacturing. FPGAs are a subset of logic devices referred to as programmable logic devices (PLDs). They consist of an array of programmable logic blocks with a connecting grid, that can be configured "in the field" to ...
SystemVerilog. SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems. SystemVerilog is based on Verilog and some extensions, and since 2008, Verilog is now part of the same IEEE standard.
Icarus Verilog is an implementation of the Verilog hardware description language compiler that generates netlists in the desired format (EDIF) and a simulator. It supports the 1995, 2001 and 2005 versions of the standard, portions of SystemVerilog, and some extensions. Icarus Verilog is available for Linux, FreeBSD, OpenSolaris, AIX, Microsoft ...
Vivado Design Suite is a software suite for synthesis and analysis of hardware description language (HDL) designs, superseding Xilinx ISE with additional features for system on a chip development and high-level synthesis. [1] [5] [6] [7] Vivado represents a ground-up rewrite and re-thinking of the entire design flow (compared to ISE). [8] [9] [10]
In digital circuit design, register-transfer level (RTL) is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals (data) between hardware registers, and the logical operations performed on those signals. Register-transfer-level abstraction is used in hardware description languages (HDLs) like ...
