1. Setting PVS to QRC av_extracted Flow with tsmc28 (& tsmc40) LVS
Shows you how to put in place the PVS(LVS)-QRC(av_extracted) view using TSMC files.
2. Mismatch Contribution in Virtuoso Analog Design Environment GXL
Mismatch contribution analysis is a Monte Carlo post-processing feature that helps in identifying the important contributors to mismatch variation. You can then modify the identified devices in the design to make the design less sensitive to device mismatch variation in IC 6.1.6.
Rapid Adoption Kits
3. Substrate/Well Connectivity Extraction
The substrate/well connectivity enhancements were made in VLS XL to help designers work more effectively on designs at lower geometry nodes.This RAK steps through the Extractor capabilities -- detecting short on a same substrate, creating isolated substrate and how to break a propagated connectivity on the same layer based on a generic 90nm PDK. IC6.1.6 ISR5
4. Making a layout XL-compliant using Update Binding (XLME)
Often layout engineers have existing or legacy layouts that they wish to use in VLS XL to take advantage of the connectivity-driven flow. With the introduction of the Update Binding functionality in IC6.1.6, it is now possible to quickly make a legacy layout fully XL-compliant. IC6.1.6 ISR6.
5. Routing Constraint Interoperability - AoT Flow (Analog on Top)
This workshop demonstrates the capability to capture routing constraints in either Virtuoso or Encounter Digital Implementation System, propagate routing constraints across hierarchical boundaries, perform routing (using NanoRoute and the Virtuoso Wire Editor) while honoring constraints, and validate the routing results against the original routing constraints using PVS-cv. EDI 13.2 and Virtuoso IC6.1.5 ISR17.
6. Custom Digital Placement
The Custom Digital Placer is used to implement small digital designs with several thousand placeable components. The Custom Digital Placer can also be used to place a few transistor-level devices along with standard cells (mixed mode). IC6.1.6 ISR6
