Modelling Programmable Logic Devices and Reconfigurable, Microprocessor-Related Architectures

This paper introduces two basic models for describing the space efficiency and the throughput of configurable devices. The first model focuses on available Programmable Logic Devices (PLD) and shows the relationships of silicon space and computing time to the block size. This model is further subdivided into a particular one for Complex PLDs (CPLD) and one for Field-Programmable Gate Arrays (FP...

Programmable logic devices

Advances in programmable logic devices' architectures are making PLDs suitable for a plethora of applications. The devices now find use in state machines and other highly sequential circuits. In the past two years, bipolar PLD operating speeds have doubled, and emerging CMOS PLDs offer four times the circuitry per chip than the older bipolar versions offered. CMOS PLDs also offer lower operatin...

Thermal Testing on Programmable Logic Devices

In this work, an FPGA-oriented temperature monitoring scheme is presented. A control circuit enables a ring-oscillator during a short period and measures its output frequency, a magnitude that is a function of the die temperature. Several sensors have been constructed using Xilinx chips, obtaining sensitivities between 17 kHz per °C and 77 kHz per °C. The characterization of self-heating, match...

Application Of Programmable Logic Devices In Safety Systems

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 ...
