However modifying the design and the process through the real wafer processing of fabrication increases the time to market. This paper describes an efficient simulation approach for a new IC process centering method based on the SPICE model and E-tests (i.e., threshold voltage and saturation current). This methodology enables obtaining the optimal E-tests for improving the performance of high speed devices, before changing the real process conditions. In addition, the Response Surface Method (RSM) is used as a significant statistical tool for this new procedure. The validity and efficiency of this approach are proven by applying it to an IC process design centering problem for ALPHA CPU.","PeriodicalId":110117,"journal":{"name":"Proceedings of the IEEE 2001. 2nd International Symposium on Quality Electronic Design","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134642786","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}

The device dimension of ESD clamp devices in analog ESD protection circuit can be reduced to have a much small input capacitance for high-frequency applications, but it can still sustain a high HBM and MM ESD level. To find the optimized device dimensions and layout spacings on ESD clamp devices, a design model is developed to keep the input capacitance as constant as possible (within 1% variation).","PeriodicalId":110117,"journal":{"name":"Proceedings of the IEEE 2001. 2nd International Symposium on Quality Electronic Design","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122784050","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}

Using the boundary scan delay chain for cross-chip delay measurement and characterization of delay modeling flow 利用边界扫描延迟链进行跨片延迟测量和表征的延迟建模流程

Schmid, Timo Schüring, Christoph Smalla","doi":"10.1109/ISQED.2001.915253","DOIUrl":"https://doi.org/10.1109/ISQED.2001.915253","url":null,"abstract":"For ASICs/SOCs/lCs it is often very important to have an easily accessible delay measurements path for several reasons. The delay of a long path running across the whole chip through lots of instances (inverters, MUXes) makes it possible to measure the final process parameters of an ASIC/IC within the best and worst case production process window. This information is very important for production testing and assembly at the vendor site. But very often this information is also necessary at circuit pack level, system test level and even in the field - when in the case of problems (functionality, timing, debugging) it should be known which \"quality level\" the ASIC/IC device has reached. Also for characterization of the delay modeling during the different design phases (estimation, floorplanning, trial and final layout) such a dedicated delay path may help in qualifying the delay models. We propose to use a new standard methodology to address these issues by definition of a dedicated delay path. It is called \"Boundary Scan Delay Chain\" (BSDC). We use the Boundary Scan data register according to IEEE1149.1 to get a delay chain across the chip. Only a slight modification of the boundary scan cell (e.g. BC 1, BC 4) is necessary. The resulting new functionality still conforms to IEEE1149.1.","PeriodicalId":110117,"journal":{"name":"Proceedings of the IEEE 2001. 2nd International Symposium on Quality Electronic Design","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125577912","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}

The voltage at power bus nodes is expressed in terms of gate currents using sensitivity analysis. Circuit timing information, functionality and logic dependencies are employed to find maximum simultaneous high-to-low, and low-to-high switching in a subinterval of a clock cycle. The sensitivity information together with an optimization procedure are applied to find bounds on the voltage drop in targeted bus nodes. The effects of signal statistical variations on the results are automatically included in our method. Comparisons to exhaustive HSPICE simulation of circuits extracted from layout are used to validate our approach.","PeriodicalId":110117,"journal":{"name":"Proceedings of the IEEE 2001. 2nd International Symposium on Quality Electronic Design","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122433647","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}

The extremely demanding time frame for the introduction of such a system requires a development approach reducing the design risk to a minimum especially for the end user receivers. As an integral part of the terminal the digital baseband processor is one of the most challenging receiver components in terms of development and validation effort. The complexity of the ASIC design with initially estimated 500,000 to 1,000,000 gate equivalents has driven the deployment of a real-time prototyping system. To assure real-time and identical functionality on both FPGA prototype and ASIC behavioral synthesis was used for timing-critical and computationally intensive building blocks. The design and validation methodology was successfully implemented. The ASIC will be introduced in the first generation of mobile radio receivers for digital audio broadcasting in the United States.","PeriodicalId":110117,"journal":{"name":"Proceedings of the IEEE 2001. 2nd International Symposium on Quality Electronic Design","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131634319","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}

The QES can be used by an IP provider for: a simple checklist of quality factors and metrics; individual IP quality evaluation; as an input to IP Integrators for evaluation.
