Programmable devices containing lookup tables (LUTs) and programmable logic arrays (PLAs) provide a heterogeneous target platform for user designs. Present commercial tools, which target these hybrid devices, require hand partitioning of user designs to isolate logic for each type of logic resource. In this paper, an automated technology mapping tool, hybridmap, is presented that identifies des...

in this article, a speed control of dc motor is designed and illustrated using fuzzy logic-based programmable logic controller (plc). the dc motor is an attractive part of electrical equipment in many industrial applications requiring variable speed and load specifications due to its ease of controllability. the designed system is consisted of three main parts including programmable logic contr...

A test procedure for testing mainly the boundary scan cells, and testing partially the test access port controller in programmable logic devices, and field programmable gate array devices, is suggested. The test procedure involves; the configuration of programmable logic devices or field programmable gate array device, the application of test vectors, and finally the verification of the respons...

Every user of programmable logic at some point faces the question: “How large a device will I require to fit my design?” In an effort to provide guidance to their users, Field Programmable Gate Array (FPGA) manufacturers, including Xilinx, describe the capacity of FPGA devices in terms of “gate counts.” “Gate counting” involves measuring logic capacity in terms of the number of 2-input NAND gat...

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...

For last few decades, reconfigurable devices have been extensively used in digital systems. Reconfigurable computing using FPGA devices provide a method to utilize the available logic resources on the chip for various computations. The basic ability of reconfigurable computing is to perform computations in hardware to increase performance, while retaining the flexibility of application software...

0272-1732/00/$10.00  2000 IEEE Traditionally, undergraduates in electrical and computer engineering study the design and implementation of a simple computer and then develop their own designs. In recent years, computer design courses have for the most part taken a simulation-only approach. Rapid prototyping techniques and a new generation of large field-programmable logic devices (FPLDs) enabl...

We discuss the unique capabilities of programmable logic devices (PLDs) for experimental quantum optics and describe basic procedures of design and implementation. Examples of advanced applications include optical metrology and feedback control of quantum dynamical systems. As a tutorial illustration of the PLD implementation process, a field-programmable gate array controller is used to stabil...
