Abstract :
As the family of Alpha microprocessors continues to scale into more advanced technologies with very high frequency edge rates and multiple layers of interconnect, the issue of characterizing inductive effects and providing a chip-wide design methodology becomes an increasingly complex problem. To address this issue, a test chip has been fabricated to evaluate various conductor configurations and verify the correctness of the simulation approach. The implementation of and results from this test chip are presented in this paper. Furthermore the analysis has been extended to the upcoming EV7 microprocessor, and important aspects of the derivation of its design methodology, as pertains to these inductive effects, are discussed
