![]() The HBOOK file be stored on hard disk for small amount of data, or into Exabyte tape file for large amount of data. Simulation results are written in a HBOOK file as a NTUPLE, to be examined by HBOOK in batch model or graphics, and analyzed by statistical procedures available. Data transfer between CPS processes for a modified version of SPICE2G6 is done by RAM memory, but can also be done through hard disk files if no source files are available for the simulator, and for bigger simulation outputs files. CPSPICE simulates electronic circuits by Monte Carlo method, through several different processes running simultaneously SPICE in UNIX parallel computers or workstation farms. It is part of a set of tools being develop, intended to help electronic engineers to design, model and simulate complex systems and circuits for High Energy Physics detectors, based on statistical methods, using the same software and methodology used by HEP physicists for data analysis. International Nuclear Information System (INIS)ĬPSPICE is an electronic circuit statistical simulation program developed to run in a parallel environment under UNIX operating system and TCP/IP communications protocol, using CPS - Cooperative Processes Software, SPICE program and CERNLIB software package. A comparison of temperature fields of electronic circuit simulator with his uniform and non-uniform cooling.ÂĮlectronic circuit design with HEP computational tools In the work described structural variants of devices for cooling electronic circuit boards, made on the basis of thermoelectric batteries and consumable working substances, implementing uneven process of removing heat from heat-generating components. Futhermore, the results of the dc analysis can be used directly as the initial conditions for the ac and transient analyses.ĭEVICES FOR COOLING ELECTRONIC CIRCUIT BOARDS It is capable of conducting dc analysis, ac analysis, and transient analysis of a circuit. ![]() Electronic circuit analysis language (ECAL) is a comparatively simple and easy to use circuit analysis special language which uses the FORTRAN language to carry out the explanatory executions. The special language for electronic circuit analysis is the foundation of computer aided design or computer aided circuit analysis (abbreviated as CACD and CACA) of simulated circuits. The computer aided design technique is an important development in computer applications and it is an important component of computer science. From a mathematical formulation of the electronic circuit the following analysis are possible: DC, AC, transient, noise, distortion, Worst Case and Statistical.Įlectronic Circuit Analysis Language (ECAL) The history and description of SPICE-like simulators are given. Most analogue simulators have evolved from SPICE. These concepts have been implemented in the program SPECS ( Simulation Program For Electronic Circuits and Systems) and examples of simulations are given.Įnergy Technology Data Exchange (ETDEWEB) In order to speed up the simulation, MOS networks are subdivided in small pull-up and pull-down transistor configurations that can be preanalysed and prepared for fast evaluation during the simulation. Both bounds are expressed in terms of states. In order to represent the "unknown" state, a signal consists of both an upper and a lower bound defining a signal envelope. The simulator is of mixed-mode nature in that it can model portions of a design at either the gate or transistor level. ![]() State changes are scheduled in the same fashion as in the case of gate-level simulators, making the simulator event-driven. Signals are known only in terms of these states thus allowing all current computations to be table driven. A new logic state concept is introduced which consists of a set of discrete voltage steps. In this dissertation an approach is presented which adds a timing capability to switch-level simulators at relatively little extra CPU cost. Used strictly for functional verification and fault simulation, switch -level simulation can only give very rough estimates of the timing of a circuit. Recently the introduction of switch-level simulators which model MOS transistors in terms of switches has helped to overcome the long runtimes associated with full circuit simulation. Circuit simulation has been used for over two decades to verify the behavior of designs. Simulation tools are central to the development and verification of very large scale integrated circuits.
