| Abstract | Traditionally, power integrity engineer uses simulated transient current profile, icc(t) from the Circuit Designer as input to power delivery network, PDN to simulate worst case transient power noise. However, it is extremely difficult to simulate the maximum current profile from large circuit or logic block. It increases the difficulties when the circuit/ logic run at random application. The paper discusses the reverse engineering method to regenerate high speed stimulus current from the given PDN and measured voltage waveform. The paper firstly verified that the reverse engineering method proven to be accurate in HSPICE simulation. Then measurement technique is applied to an Intelreg Core 2 Duo Processor running stress test under various random applications. The paper also discusses the precision and reproducibility of high speed current profile, icc(t) by using this reverse engineering technique. The finding enables the transient power simulation of a PDN can be done without depending on the simulated CKT/ Logic block icc(t) data. The method also improves the correlation work to be done between the pre-silicon simulated icc(t) with the measurement data from the lab. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
