以SOPC為基礎之測試系統設計

SOPC-based Testing System Design

指導教授 : 翁慶昌

摘要


本論文提出兩種以SOPC (System On a Programmable Chip)為基礎之測試系統設計方法;其中一個是低成本、高品質的CMOS影像感測器(CMOS Image Sensor, CIS)之測試平台設計,另一個則是提升IC可靠度的Burn-In測試系統。本論文共分成三部分,在第一部分先介紹一個以多主從系統架構所實現的嵌入式即時影像處理平台,並在該平台上建構CMOS及LTM主控器等兩個硬體加速電路模組來加快影像擷取、前處理運算與影像即時顯示;此設計可減少軟核心處理器Nios II處理影像的運算時間,也可加強影像系統之即時分析能力,因此很適合應用於CIS之影像分析與數位信號處理等系統之應用設計上。論文的第二部分係以上述架構為基礎,提出一種不同於產業界現行設計方法的CIS測試架構,其可打破測試機台的專用性來降低測試成本。傳統的CIS測試機台有其專用性,價格難以降低;本論文提出以SOPC為基礎之CIS影像測試平台,搭配一般非專用功能的測試機共同組成微型化、低價位之CIS測試架構,不僅可以降低成本,更因影像傳輸距離的降低,使得影像測試品質得以大幅提升。在論文的最後一個部分,主要是討論一個IC Burn-In系統之設計,在現今IC的耗電量增加下,使得IC本身也會散發高熱,如何設計一個恆溫的系統是個很大的挑戰,且Burn-In測試對於提升IC的可靠度有著關鍵性的影響。本文提出以SOPC為基礎之模糊控制器( Fuzzy Controller )設計,來控制Burn-In系統的加熱器與風扇轉速,並取得其動態平衡。最後的實驗結果得知,本論文所實現之模糊控制器除了具有極佳的反應時間外,也可在滿足規格需求下有效改善系統的性能,驗證所提之架構確實可提供產業界多種測試問題有效之解決方案。

In this dissertation, two SOPC-based methods for testing systems are proposed. One is a low cost and high quality testing platform designed by CMOS Image Sensor (CIS), and the other is a Burn-In testing system that can effectively enhance the IC reliability. There are three parts in this dissertation. First, an embedded real time image processing platform with a CMOS Master module and a LTM Master module is introduced. These modules can accelerate the image acquisition and pre-processing operation and real- time image display. This platform can reduce the image processing operation time of Nios II core processor and enhance the real time analysis capability of the image system. It is very suitable to be applied in the design of CIS image analysis and digital signal processing system. Second, a CIS testing architecture is proposed to break the specific usage nature of the testing machine to reduce the test cost. Traditional CIS testing equipment has difficulty to drop the price because of its specific usage. In this dissertation, a SOPC based CIS image testing platform is proposed, which can be associated with a general non-specific usage function testing equipment to compose together the miniaturized and low cost CIS testing architecture. Due to the reduction of the image transfer distance, the image testing quality can be enhanced greatly. Finally, an embedded fuzzy controller is used to control the rotational speed of the heater and electric fan of Burn-In system so that it is in a dynamic equilibrium. The realized fuzzy controller not only possess excellent response time but also improves the system performance effectively under the satisfaction of the spec requirement.
