For some time now,
industry has recognized the need for structured design methodologies that
integrate ECAD design with product data management (PDM) systems. We know that
creating an electronic product efficiently, on time, and within budget can
benefit from this. Yet this integration has not been at the level that
engineers could use during the design authoring and implementation process.
Why? Often the
integration was at some predefined milestone - design reviews, schematic
complete, or layout complete. Worse, the integration was not at a granular enough level for engineers to benefit from it.
For years, Cadence has partnered with PTC to tie Allegro
Design Workbench functions to PTC's widely adopted PLM software PTC Windchill to enable
engineering teams to improve productivity. Until recently, while engineers have
been able to work on blocks in a given design in parallel, the process for
efficiently checking out, checking in, and tracking changes to those blocks has
"It was a tarball approach," says Hemant Shah, Product
Management Group Director, Cadence (pictured, right). "Grab this file, this file, and this
file and put it all together, tarball it and put it into Windchill. It lacked
the granularity and process that engineers need."
It can take hours to upload and download that data tarball,
For example, some users do schematic design, some do the
layout design, and then some do signal integrity analysis. "Each one of
those groups of people couldn't check in and check out pieces of data that were
managed in a structured way," he said.
That's now changed, as Cadence has integrated its Team
Design cockpit more tightly with PTC Windchill.
allows engineers to manage what we call work-in-progress design data and do it
at the block level. A hierarchical schematic has multiple blocks and engineers
can pull up their blocks, and we provide the capability to check-in, check-out
from PTC Windchill from ECAD desktop tools."
In this way, engineers working together can update their blocks
independently of each other but provide the visibility to each other as to which
version is available and is the latest, he added.
