Powerful new tool facilitates first-time-right analog & high voltage design implementation in even the most challenging of scenarios.
Continuing to drive innovation in analog/mixed-signal IC fabrication, X-FAB Silicon Foundries SE (http://www.xfab.com/) has announced the introduction of SubstrateXtractor.
Unwanted substrate couplings can impact modern IC developments, causing parasitic effects that are damaging to overall performance. Engineers have to deal with this by taking a slow and laborious ‘trial and error’ approach, which calls for the allocation of many hours of experienced engineers’ time while numerous different design iterations are made and then experimented with.
The objective of SubstrateXtractor is to change all that. Created in partnership with Swiss EDA software vendor PN Solutions, and based on its innovative PNAware product, this is the semiconductor industry’s first commercially available tool dedicated to addressing the simulation of large signal substrate parasitic effects. Working in conjunction with X-FAB’s established simulation libraries, it allows engineers to investigate where potential substrate coupling issues could occur and make the changes necessary to eliminate them (via better floorplanning, guard rings, etc.) before the initial tape-out has even begun.
Through it, engineers will gain full visibility of all the active and passive elements within the substrate and be able to experiment with different simulations in order to find a design concept that delivers maximum substrate coupling immunity within the project’s particular parametric constraints. Furthermore, they are able to determine the minimum number of substrate contacts and guard rings needed for a project, no matter how complex and sophisticated it is – thereby resulting in more effective utilization of the available area.
