to deliver a mixed-signal
sensor interface integrated circuit (IC) in record time. By working
with the latest AMIS mixed-signal application specific integrated
circuit (ASIC) design flows and methodologies, the time between
ASIC definition and the delivery of an approved quality part was
less than 50 weeks.
The 'Marble' sensor interface IC is a critical component of Emerson's
Rosemount 3051C pressure transmitter. Strong sales of this instrumentation,
coupled with an unexpected 'end-of-life' announcement from the incumbent
supplier of the Marble part, put pressure on the Emerson team to
develop a newsolution in a very short timeframe. Having worked with
AMIS on other ASIC projects, this team turned to the company's mixed-signal
design specialists to help them develop the replacement sensor interface
IC.
A key factor behind the successful development of the Marble product
within the tight timeframe was that Emerson's ASIC toolsets and
design methodologies were already aligned with those of AMIS.

Because of this, with some
AMIS support on design and layout, the company was able to hand-off
a design to AMIS that could be put into production almost immediately,
resulting in the short time between hand-off and device tape-out.
‘With end-of-life stock running out and Emerson needing Rosemount
products at an ever-increasing rate, we were under real pressure
to deliver in very tight timescales,’ said Terry Krouth, vice
president technology, Emerson Process Management.
‘Strong cooperation with the AMIS team, and the alignment of
our methodologies and tools with theirs, significantly shortened
the time from initial design to final delivery. In fact, this is
Emerson's fastest ASIC turn ever from definition to an approved
quality part.’
Bob Klosterboer, AMI Semiconductor's senior vice president for integrated
mixed-signal products added, ‘The success of the Marble project
highlights our flexibility in working with customers' own ASIC design
teams. This was the first design for Emerson using our new design
flows and methodology, and this ensured successful delivery of 'right
first time' product.
