WebAIM's WCAG 2 Checklist

WCAG 2 Checklist Principle 1: Perceivable Web content is made available to the senses - sight, hearing, and/or touch Guideline Text Alternatives Provide text alternatives for any non-text content Success Criteria Recommendations Non-text Content (Level A) Images, form image buttons, and image map hot spots have appropriate, equivalent alternative text. Images that do not convey content, are decorative, or contain content that is already conveyed in text are given null alt text (alt="") or implemented as CSS backgrounds. Linked images have descriptive alternative text. Equivalent alternatives to complex images are provided in context or on a separate linked page. Form buttons have a descriptive value. Form inputs have associated text labels.

are used for tabular data and data cells are associated with their headers. Data table captions, if present, are associated to data tables. Text labels are associated with form input elements. Related form elements are grouped with fieldset/legend. ARIA labelling may be used when standard HTML is insufficient. 1.3.2 Meaningful Sequence (Level A ...

FPGA Logic Cells Comparison - Sharif

ee.sharif.edu

FPGA Logic Cells Comparison In this article we compare logic cells architectures that are used in modern FPGAs: Xilinx (both Virtex-5 and earlier), Altera and Actel. Introduction FPGA (Field Programmable Gate Array) is an integrated circuit containing a matrix of user-programmable logic cells, being able to implement complex digital circuitry.

Logic Devices include simple as well as high-density PLDs. In 1985 Xilinx Corporation came out with the first FPGA. It introduced the Logic Cell Array (LCA) and was the building block for all FPGAs to follow. It contained a pool of independent logic cells and multiple routing resources that allowed any logic cell
