Toshiba's Broadband IC design group is tasked with producing the
company's highest performance integrated circuits. In 2004, they were
challenged to produce floating-point units that would perform at 2 Ghz
using a 65 nm process. Hardly a trivial task -- so Toshiba turned to
CellMath tools for assistance.
Toshiba used a combination of CellMath tools, IP and design services to
assist its engineers in producing the world's fastest integrated
circuit for its time. The CellMath design services group optimized
Toshiba's RTL code, investigated datapath architectures, synthesized the
design for performance and area using its patented silicon
math IP, and returned optimized netlists to Toshiba. Consultants then provided guidance to Toshiba's physical design team to
efficiently integrate the floating-point units into the target IC.
Toshiba also licensed CellMath Designer to design ICs for other
consumer electronics applications in their 65 nm process technology.
After extensive evaluation using real designs, it was clear to Toshiba's
management that CellMath Designer would help them achieve their
aggressive performance goals and reduce die area.
Toshiba was able to meet all of their industry-leading performance goals
while realizing a significant area and power savings. In addition,
Toshiba's engineers were able to quickly implement CellMath Designer in
their existing design flow.
 "Our
datapath results show an average of 20 percent area savings. Learning
CellMath Designer was easy; our design team was able to use the tool and
achieve good results after just two afternoons of training."
