Legend offers process optimization tool
CRUZ, Calif. — Extending its CharFlo_Memory! characterization software
to semiconductor process optimization, verification, and statistical
characterization, Legend Design Technology has introduced
CharFlo-Memory!-TD. The extended product aims to enhance productivity
and yields for nanometer ICs.
For process verification,
CharFlo-Memory!-TD provides electrical measurements of timing, power,
frequency, and reliability. After process parameters are converted to
Spice models, designers can use Legend's MSIM circuit simulator to
verify the impact of any process change.
As a pseudo "design of
experiments" tool, CharFlo-Memory!-TD optimizes processes by
characterizing and simulating test circuits over a combination of
process parameters. For statistical characterization, it takes in Spice
models that reflect the distributions of process parameters, and then
produces statistical results of electrical measurements from
characterization and simulation.
You-Pang Wei, Legend
president and CEO, said that CharFlo-Memory! has been adopted by major
foundries, IDMs, and fabless design houses. He named TSMC and UMC as
customers. The extended product complements costly "design of
experiments" done on silicon, he said.
CharFlo-Memory!-TD is available now from Legend Design, starting at $250,000 for a perpetual license.
