Peak power estimation of VLSI circuits: new peak power measures

New measures of peak power are proposed in the context of sequential circuits, and an efficient automatic procedure is presented to obtain very good lower bounds on these measures, as well as providing the actual input vectors that attain such bounds. Automatic generation of a functional vector loop for near-worst case power consumption is also attained. Experiments show that vector sequences g...

Spice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits

An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

Test Power Reduction by Simultaneous Don’t Care Filling and Ordering of Test Patterns Considering Pattern Dependency

Estimating and minimizing the maximum power dissipation during testing is an important task in VLSI circuit realization since the power value affects the reliability of the circuits. Therefore during testing a methodology should be adopted to minimize power consumption. Test patterns generated with –D 1 option of ATALANTA contains don’t care bits (x bits). By suitable filling of don’t cares can...
