the clear logic cl3000 laser processed logic device (lpld ? ) family offers the ultimate combination of performance, flexibility, and cost. this family is a system level second source to altera max ? 3000a products. for designs not requiring in- system reprogrammability, design verification can be performed using the programmable altera devices, and clear logic lplds can be used for low cost, high volume production. clear logics innovative laser-based technology eliminates nre costs, test vector development, ordering minimums and long lead times. no re-simulation or re-layout is required, as the device uses a cell-based, pld-like architecture. clear logics nofault ? technology ensures complete test coverage through the use of specialized testing modes which are transparent to the user. the clear logic cl3000 laser processed logic device family is based upon a large array of macrocells. each macrocell contains a logic array with five product terms, a product-term select matrix, and a configurable register. a group of sixteen macrocells forms a block. laser-configured metal fuses implement logical functions and control signal routing. laser configuration provides reduced cost and enhanced performance. these inherent performance benefits include extremely consistent propagation delays, reduced power consumption, and improved immunity to noise and upset events. for further information on designing with the cl3000 lpld family (see cl7000), please consult the following documents: u an-01: requesting a first article. this document provides instructions on how to submit a bitstream file for generation of first articles. u an-02: clear logic packaging guide. this document provides specifications and drawings for packages used by the cl7000 family. u an-09: cl7000 technology white paper. this document outlines the technologies employed by the cl7000 lpld family. u an-10: calculating cl7000 power consumption. this document provides guidelines for calculating power consumption based on design characteristics. u an-11: cl7000 test methodology. this document describes how clear logic provides 100% stuck-at fault coverage. description cl3256a laser processed logic devices page 122 additional information
cl3256a laser processed logic devices page 123 u an-12: cl7000 lpld timing and function compatibility. this document shows how a seamless conversion from cpld to asic can be achieve with no additional engineering with clear logic.
