Two 32 bits pseudorandom uniform noise generators, a Mersenne-Twister (MTW) and a Linear Feedback Shift Register (LFSR), were implemented on a FPGA and evaluated to prove its validity in a proposed ADC built-in self-test (BIST) [1,2]. The BIST solution is based in the histogram method and the obtained results were compared with the ADC standard static test and with a histogram test using Gaussian noise as stimulus. A pipeline ADC and a DAC, both with a resolution of 10 bits, the Gaussian noise generator and the BIST solution were modeled and simulated in MATLAB. The obtained results shown that the histogram test with an UNG as a stimulus could be a powerful method to characterize 10 bits ADCs with the accuracy needed. Compared with the Gaussian histogram test, the number and complexity of the circuits is quite reduced and an adequate statistical significance is obtained with a quarter of samples, therefore the time required for tests is reduced.","PeriodicalId":191482,"journal":{"name":"2015 Conference on Design of Circuits and Integrated Systems (DCIS)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116298317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we present the modelling framework used for the evaluation of the proposed execution flow. The modelling process is presented in a step-by-step manner by means of a real-life example of implementation of super-resolution image reconstruction with description of the choices made at every stage and explanation of the reasoning behind. In the presented case the use of the proposed frame-work led to a hardware implementation with real-time capabilities.

The methodology allows different tradeoffs between fault list compression and fault representation accuracy by changing the number of strata, L. These concepts are embed them in the AIDA's framework [2][3], which is an analog IC design automation environment, and, allows the designer to select a circuit sizing and determine an efficient set of stimuli for fault detection, reducing the simulations required in the test environment.

This trend is largely due to the mathematical properties of DWPT, and particularly to its excellent locality in the time-frequency domain. Unfortunately, DWPT is also a rather demanding operation. For instance, the much known tree algorithm developed by Mallat requires large amounts of operative and storage resources. In this paper, we are proposing a novel architecture for DWPT, aiming to provide an effective performance trade-off. High throughput is achieved using only a relatively limited amount of hardware, thanks to a clever sharing of hardware resources between the low-pass and high-pass filters in the Mallat-tree algorithm, and an efficient use of the different throughput rates in different places of the architecture. The design has been modeled in VHDL at the RTL level, and synthesized using Altera Quartus II targeting an Altera Cyclone IV FPGA. The architecture is fully configurable at synthesis according to the tree depth (number of tree levels), the order of the filters and the filter coefficient quantization. Furthermore, the tree depth and filters order has little impact (only due to place and route variations) on throughput. The results obtained so far compare favorably to previous works.","PeriodicalId":191482,"journal":{"name":"2015 Conference on Design of Circuits and Integrated Systems (DCIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129734051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
