Dolphin Integration Selects Silvaco VarMan eXtreme Memory Analysis for SRAM Design At Advanced Nodes

SANTA CLARA, Calif., – June 27, 2017

Silvaco today announced that Dolphin Integration, a leading provider of power- and density-optimized memory silicon IP, has selected Silvaco’s VarMan™ for full memory statistical analysis to perform reliability qualification on SRAM memories designed using advanced process technologies.

Studying memory IP’s against variations and accurately analyzing their yield is a critical challenge faced by memory designers. Running spice simulation on a complete memory spice simulation is a demanding effort and Monte Carlo analysis is impractical even with the state-of-the-art solutions available. Whole Memory Yield estimation is still the ultimate need for memory design. This mission fulfilled by XMA (eXtreme Memory Analysis), the new innovative solution from Silvaco’s VarMan. Intuitive and easy-to-use, XMA makes it possible rebuilding and simulating the whole memory with the designer golden spice. Then XMA provides a unique capability allowing to run very efficient variation-aware analyzes for a fast fail detector and yield estimation of the whole memory.

After several years of successful usage of VarMan in various process technologies, Dolphin Integration has over the past year increased its partnership with Silvaco, integrating even further VarMan into their memory design flow. “This is the solution we were impatiently awaiting. Simulating a whole memory and analyzing accurately and quickly its yield has been a lastingly longed-for feature” said Frédéric Masson, Business Operations Manager at Dolphin Integration. “Coupling VarMan with SMASH™, our mixed-signal simulator, results in high-speed yield verification for our memory architectures and improves the overall efficiency of the electrical validation of our products, with the best time-to-market.”

“As one of the most advanced providers of memory IP, Dolphin Integration’s selection of VarMan XMA for their new generation of designs is a testament to its effectiveness,” said Firas Mohamed, General Manager of Silvaco France. “Analyzing the whole memory against variations and efficiently detecting failures and accurately estimating its yield have remained unanswered from the EDA market. The innovative VarMan XMA uniquely delivers the long-awaited and unprecedented reply to these critical needs.”

Different elements in a memory design must be analyzed with suitable variation analysis techniques. VarMan addresses three key parts of a memory system:

  • Bitcell – Analysis is often applied out to 7 sigma and beyond.
  • Sense Amp – Analog in nature, fast Monte Carlo or high sigma is used for these portions.
  • SRAM block – Larger portion of SRAM beyond the bitcell is analyzed. Extremely high capacity high sigma is required. In addition, VarMan remains robust even against highly non-linear phenomena.

VarMan is easily integrated into customer design flows and provides an intuitive, easy-to-use interface. It supports a variety of 3rd party and proprietary transistor-level simulators, and process design kits and SPICE Netlists can be loaded without modification.
