SAN JOSE, Calif — Legend
Design Technology Inc. has added a new push button ".lib
in-and-out" front end to its Char-Flow Memory embedded memory
characterization and modeling tool suite.
According to Legend Design's president and chief executive,
You-Pang Wei, the new memory compiler front end, called MSL
(MemChar SpiceCut Library), produces a .lib library format
file with information such as pin names, slopes and loading
for timing models.
The MSL tool reads in a .lib file and automatically
generates the controls for running MemChar, Legend Design's
Memory Characterization tool and SpiceCut, the company's
automated critical path circuit generator.
"We have all the pieces covered for performing embedded
memory characterization," said Wei. "CharFlo-Memory supports
both Full-Chip and Critical-path based Characterization and
Verification.Wei said users enter .lib files, Spice files and
an extracted netlist of the design. The Char-Flow produces a
refined and more accurately characterized .lib file of the
memory model as well as produces a report that gives a before
and after comparison of improvements made with Char-Flow
Legend Design also offers the MSIM matrix-inversion based
circuit simulator with optimized algorithms for memory and
standard cell characterization. The company plans to release a
"Turbo" version of the tool in the third quarter of the year
and will be previewing it at the Design Automation Conference
in June. The flow also works with third-party simulators.
The Char-Flow Memory suite starts at $200,000.
