Introduction to One-Shot DRC & Fine-Grain Physical VerificationTM Technology Platform

As process technologies advance to smaller sub-wavelength geometries such as 28nm and beyond, several new physical verification challenges have emerged.  Examples of the challenges are:

  1. the use and the number of dummy fills grow exponentially
  2. proximity effects are required to be dealt with universally and have a strong impact on yield
  3. the number of rules and related parameters grow exponentially
  4. rules are very complex and often conflicting, making coding a monumental task, and often leading to over-checking and under-checking

Today, runtimes and accuracy problems in the form of under-and over-checking are major concerns, even with the use of hierarchical DRC tools based on multi-CPU configuration.

One-Shot DRC is POLYTEDA's innovation. It is neither flat, nor hierarchical; It is done in one-shot! A layout is partitioned into smaller blocks and DRC is performed on all layers and the related rules of a block in one shot. In addition to accuracy, unlike a flat or hierarchical DRC technology, One-Shot DRC offers runtimes that:

  • are significantly faster
  • scale linearly with the number of objects to be processed
  • and are predictable

One-Shot DRC technology, PWRL, the language engine and other related technologies form a Fine-Grain Physical Verification (fgPV™) technology platform. fgPV is the foundation for all POLYTEDA's physical verification tools.
