SKILL is not an acronym; it is a name. For trademark reasons Cadence prefers it be capitalized. [2] Franz Lisp and all other flavors of LISP were eventually superseded by an ANSI standard for Common Lisp. Historically, SKILL was known as IL. SKILL was a library of IL functions.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
Spectre is a SPICE-class circuit simulator owned and distributed by the software company Cadence Design Systems. It provides the basic SPICE analyses and component models. It also supports the Verilog-A modeling language. Spectre comes in enhanced versions that also support RF simulation and mixed-signal simulation (AMS Designer).
Layout editors have moved mostly to the server world through the likes of Cadence Virtuoso and Mentor though some is still done through PC tools through tools such as L-Edit but sadly there is little choose from in the PC market though there are a few exceptions such as Magic and KLayout but these are mostly utilized for utility such as to view ...
Cadence initially acquired Gateway Design, thereby acquiring Verilog-XL. In response to competition from faster simulators, Cadence developed its own compiled-language simulator, NC-Verilog. The modern version of the NCsim family, called Incisive Enterprise Simulator, includes Verilog, VHDL, and SystemVerilog support.
In integrated circuit design, Library Exchange Format (LEF) is a specification for representing the physical layout of an integrated circuit in an ASCII format. It includes design rules and abstract information about the standard cells.
Current digital flows are extremely modular, with front ends producing standardized design descriptions that compile into invocations of units similar to cells without regard to their individual technology. Cells implement logic or other electronic functions via the utilisation of a particular integrated circuit technology.
