Application Of Programmable Logic Devices In Safety Systems
نویسنده
چکیده
The evolution of Microelectronics has made the application of Programmable Logic Devices (PLDs) inevitable in modern digital circuit designs and when they are deployed in Safety Systems, their Reliability and Safety need to be proved beyond doubt. The design will have to meet the stringent requirements. This paper provides a review of commercially available PLDs and the design methodologies to be adopted while deploying them in safety systems.

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
متن کاملAn Efficient Algorithm for Output Coding in Pal Based Cplds (TECHNICAL NOTE)
One of the approaches used to partition inputs consists in modifying and limiting the input set using an external transcoder. This method is strictly related to output coding. This paper presents an optimal output coding in PAL-based programmable transcoders. The algorithm can be used to implement circuits in PAL-based CPLDs.

متن کاملHigh integrity hardware-software codesign
Programmable logic devices (PLDs) are increasing in complexity and speed, and are being used as important components in safety-critical systems. Methods for developing high-integrity software for these systems are well-known, but this is not true for programmable logic. We propose a process for developing a system incorporating software and PLDs, suitable for safety critical systems of the high...
