Innovative RDL PEX flow with Calibre, enhances design reliability and performance
DescriptionExtracting the Parasitic effect of packaging layers, such as redistribution layers (RDL) is important to enhance the performance of the design, as seen to account for more than 10% of the total parasitic capacitance on nets near RDL layers: impacting the performance of the circuit. The Calibre nmPlatform introduces an innovative RDL calibration and extraction flow (with xRC and xACT) that enables both design houses and Foundries to optimize their PEX evaluations, taking into account the RDL effect, while relying on the Foundry-qualified decks for all base layers.
Designers can use the Calibre xRC or Calibre xACT tools to perform PEX on layouts containing RDL layers using RDL Addon rule decks that provide highly consistent extraction results on base-layers and very high accuracy correlation on nets near RDL layers. The new flow expedites the calibration and extraction process through a simple configuration of the RDL process file, relying entirely on the qualified foundry decks in evaluating parasitics on the base layers' underneath packaging.
In collab with GlobalFoundries, the results show that the new robust RDL calibration and extraction approach is supported for most versions of Foundry-qualified decks. When the flow was tested on layouts formerly exhibiting inaccuracies with conventional flows and the results were evaluated against qualified deck-based extraction, the results showed high accuracy versus the reference solver solutions (within 3%) with a more accurate insight of the final performance of the circuit after adding the RDL layers.
The Calibre RDL PEX flow enabled GlobalFoundries and design houses using GF rule decks for extraction to augment their parasitic extraction evaluations, with minor setup changes and very high accuracy.
