Dongbu HiTek adopts Mentor's Eldo for optimized cell characterization flow

WILSONVILLE, USA: Mentor Graphics Corp. announced that Dongbu HiTek has adopted the Eldo analog circuit simulator for cell library characterization flow.

During their evaluation, the Eldo analog circuit simulator demonstrated superior performance and circuit convergence over Dongbu HiTek’s existing SPICE engine. The net outcome from the adoption of the Eldo simulation is twofold: shortened overall library characterization time, and reduced reliance on a single, simulation engine methodology.

Prior to adopting the Eldo simulator, Dongbu HiTek had a single SPICE engine methodology that presented many risks of cell characterization error and suffered from slow performance and a bad convergence rate.

In contrast, the Eldo simulator provides user-friendly and comprehensive functions for library cell characterizations. Dongbu HiTek was able to insert the Eldo simulator into their existing design and verification flow, thus removing the dependency on a single solution and reinforcing their competitiveness. The new library characterization flow with the Eldo simulator shortened time to market (TTM) by improving the convergence rate and reducing the characterization time.

“Eldo provides the high-accuracy and impressive runtimes required for library cell characterization,” said Taek-Soo Kim, vice president, Dongbu HiTek. “After a thorough evaluation, Dongbu found that Eldo sped up the sign-off process of library characterization, and shortened the verification period, as Eldo provides an alternative methodology to existing SPICE engine.”

“The Eldo evaluation with Dongbu HiTek showed very positive results for them, and we were able to meet all the criteria they defined to prove the value of the tool,” said Robert Hum, vice president and general manager of the Mentor Graphics Deep Submicron Division. “We look forward to more engagements with Dongbu HiTek where our tools can be used to strengthen the competitive advantage they extend to their customers.”
