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.
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).
Specctra is a commercial PCB auto-router originally developed by John F. Cooper and David Chyan of Cooper & Chyan Technology, Inc. (CCT) in 1989. [2] The company and product were taken over by Cadence Design Systems in May 1997.

In Western musical theory, a cadence (from Latin cadentia 'a falling') is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards. [2] A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. [3]
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), [1] is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards.
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.
