Mentor Calibre 2020.2

Mentor Graphics Calibre is one of the most popular toolsthat is widely used by design organizations and foundries. Calibrehas different modules that perform a variety offunctions post-tapeout. Thechallenge ofthe post-tapeout workflow ismaintaining tight control for high waferyield that would lead to a reduction inthe time-to-mask and operation costs. Whilesome of the workloads from modules such asscatter barand bias in the pre-OPC stage arememory intensive, the workloads generated from PM, OPC,and MDP are latency intensive. They rely on the performance of the storage, network,and computeinfrastructure in ordertosupport and complement the speed and quality of Calibre.

Mentor Graphics Calibre is one of the most commonly usedtools in the silicon on chip (SoC) manufacturing process. This processhandles different parts of the workflow from Calma Graphic Data System (GDSII) to mask flow, providing high wafer yield and reducing the cost of operation. The input files provided from the chip design houses include physical details of SoCsin a GDSIIorOpen Artwork System Interchange Standard (OASIS)format. While Calibreas an application is getting more optimized to reduce the time to mask, the underlying storage infrastructure also plays a significant role on turnaround time (TAT).The infrastructureconsists of network file share storage, the network layer, and the compute farm. NetApp storage is primarily used to store the GDSII/OASIS files and the intellectual property filesin a shared file system accessed by Calibrefrom the compute farm nodes over Network File System(NFSv3).
