EEsof
PathWave Design is a division of Keysight Technologies that was formerly called EEsof ( ; electronic engineering software). It is a provider of electronic design automation (EDA) software that helps engineers design products such as cellular phones, wireless networks, radar, satellite communications systems, and high-speed digital wireline infrastructure. Applications include electronic system level (ESL), high-speed digital, RF-Mixed signal, device modeling, RF and Microwave design for commercial wireless, aerospace, and defense markets. History EEsof was founded in 1983 by an entrepreneur, Charles J. ("Chuck") Abronson, and a former Compact Software employee, Bill Childs. EEsof's first products included high-frequency circuit simulators such as Touchstone and Libra. Although the Touchstone simulator itself is obsolete, its eponymous file format lives on. EEsof was acquired by Hewlett-Packard in 1993 and later spun out first as part of Agilent Technologies in 1999 and then as p ...

Optimization Systems Associates
Optimization Systems Associates (OSA) was founded by John Bandler in 1983. OSA produced the first commercial implementation of space mapping optimization to enhance the speed and accuracy of engineering design. OSA’s primary thrust was in computer-aided design (CAD) and simulation and optimization of radio-frequency and microwave circuits and systems. Its products included developments of Bandler's space mapping concept and methodology, which facilitates effective modeling and design optimization of computationally intensive engineering systems. History Bandler founded OSA in 1983 to commercialize optimization methodology and algorithms which he and his colleagues had developed. OSA's first major project was the reengineering of key software for simulation and optimization of waveguide multiplexers for satellite communications under contract to COM DEV International. In the 1980s OSA contributed optimization methodology and algorithms to EEsof’s early microwave CAD software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compact Software
Compact Software was the first commercially successful microwave computer-aided design (CAD) company. The company was founded in 1973 by Les Besser to commercialize his eponymous program COMPACT (Computerized Optimization of Microwave Passive and Active CircuiTs), released when he was at Farinon Electric Company. History Besser began working on simulators during his employment at HP (1966–1969), using the BASIC computer language and time-sharing computers. After leaving HP, he joined the newly formed microwave division of Fairchild Semiconductor, where he authored his first-generation program, SPEEDY, in 1970 to promote Fairchild's transistors. SPEEDY lacked the optimization feature, represented by the 'O' in the COMPACT acronym, but included a large s-parameter database with the all Fairchild's bipolar and GaAs microwave transistors. Fairchild customers had access to that database through SPEEDY. Besser later converted another program, originally written for his graduate thesi ...

Touchstone File
A Touchstone file was originally a proprietary file format for the eponymous frequency-domain linear circuit simulator from EEsof, launched in 1984 and acquired by HP. The simulator has been called HP/EEsof, then its engine has been successively included in the jOmega and ADS software suites and it is now owned by Keysight. The Touchstone simulator has long since been superseded, but its file format lives on. A Touchstone file (also known as an S''n''P file after its set of file extensions) is an ASCII text file used for documenting the ''n''-port network parameter data and noise data of linear active devices, passive filters, passive devices, or interconnect networks. An example of the format of the S-parameter section is given in the article about S-parameter Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by electrical signal ...

FEM Element can perform electromagnetic simulation of arbitrarily-shaped, passive three-dimensional structures. It is aimed at providing 3D EM simulation to designers working on RF circuits, MMICs, PC boards, modules, and signal integrity applications. It provides a full 3D electromagnetic field solver, a solid modeling GUI, and fully automated meshing and convergence capabilities for modeling arbitrary 3D shapes such as connectors, machined parts, components, bond wires, antennas, and packages. FEM Element is available with integration into Keysight EEsof's Advanced Design System (ADS) and EMPro platforms. It was originally called Electromagnetic Design System (EMDS).

Nakhla, "Microwave in Canada," IEEE Microwave Magazine, vol.13, no.3, pp. 87-106, 2012. engineer, entrepreneur, artist, speaker, playwright, and author of fiction and nonfiction. Bandler is known for his invention of space mapping technology and his contributions to device modeling, computer-aided design, microwave engineering, mathematical optimization, and yield-driven design. Early life and education The only child of parents who escaped from Nazi-occupied Vienna to Cyprus, from where they were subsequently evacuated along with other Jewish refugees in 1941, Bandler was born in Jerusalem. After the War, his parents returned to Cyprus, where Bandler attended the Junior School in Nicosia, and, for a year, The English School in Nicosia. After a brief stay in Vienna in 1956, he left for England and completed his schooling in London. He ent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of EDA Software
This page is a comparison of electronic design automation (EDA) software which is used today to design the near totality of electronic devices. Modern electronic devices are too complex to be designed without the help of a computer. Electronic devices may consist of integrated circuits (ICs), printed circuit boards (PCBs), field-programmable gate arrays (FPGAs) or a combination of them. Integrated circuits may consist of a combination of digital and analog circuits. These circuits can contain a combination of transistors, resistors, capacitors or specialized components such as analog neural networks, antennas or fuses. The design of each of these electronic devices generally proceeds from a high- to a low-level of abstraction. For FPGAs the low-level description consists of a binary file to be flashed into the gate array, while for an integrated circuit the low-level description consists of a layout file which describes the masks to be used for lithography inside a foundry.

Software Companies Based In California
Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of clou ...

Finite-difference Time-domain Method
Finite-difference time-domain (FDTD) or Yee's method (named after the Chinese American applied mathematician Kane S. Yee, born 1934) is a numerical analysis technique used for modeling computational electrodynamics. History Finite difference schemes for time-dependent partial differential equations (PDEs) have been employed for many years in computational fluid dynamics problems, including the idea of using centered finite difference operators on staggered grids in space and time to achieve second-order accuracy. The novelty of Yee's FDTD scheme, presented in his seminal 1966 paper, was to apply centered finite difference operators on staggered grids in space and time for each electric and magnetic vector field component in Maxwell's curl equations. The descriptor "Finite-difference time-domain" and its corresponding "FDTD" acronym were originated by Allen Taflove in 1980. Since about 1990, FDTD techniques have emerged as primary means to computationally model many scientific and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
