Alcatel-Lucent Reduces Design Time by Eliminating File Translation Issues Between PCB and High-Frequency Design


The Design Challenge

The circuits created by the PHC must conform to the electrical and physical requirements for the systems of which they will be a part. Because these systems tend to evolve as they are developed, a great deal of flexibility is required, which has been hampered for many years because the PHC was forced to maintain two separate component libraries. When beginning an RF or microwave design, the footprint had to be synchronized and verified with both the Mentor Graphics printed circuit board (PCB) software tools and AWR's high-frequency design software.

After the layout was complete, data was transferred via DXF (data exchange format) from AWR's Microwave Office software to Mentor Graphics Expedition. However, there was no way to perform bidirectional data transfer in order to import the microwave schematic or symbols to Mentor's DXDesigner, or to export circuit modifications performed in Expedition back to the Microwave Office platform. The increasing complexity of the team's design coupled with the sheer volume of its workload made this productivity roadblock unacceptable.

What design problem did AWR's software help you to solve?

AWR Connected™ for Mentor Graphics Expedition, for which the PHC was a beta site, has helped the design team overcome its previous productivity roadblocks and has, in just a few months, yielded significant reductions in design time. With AWR Connected for Mentor Graphics Expedition, there is no library duplication, since the dynamically linked software utility automatically creates a complete AWR library file (symbols, part numbers, substrate definitions, footprints, padstacks, and layer process) directly from the Mentor tools and automatically updates the library file whenever there is a Mentor-invoked change. The software enables real-time, seamless bidirectional transfer of schematic and layout between the two tools, so that the schematic and layout can be sent from the Microwave Office environment to Mentor tools, modified, and sent back to Microwave Office.

In addition, Microwave Office circuit simulation and analysis can be driven from Mentor, and a Mentor PCB can be linked to many Microwave Office projects. This can be performed locally, throughout the PHC, or even throughout Alcatel-Lucent via the Internet. Perhaps fundamentally most important for the PHC design teams is the assurance that they will always have the correct footprints and library when performing an RF simulation. Now that AWR Connected for Mentor Graphics Expedition has been verified through rigorous testing, the PHC will further leverage its ability to link the formerly separate and redundant high-frequency simulation and PCB domains.
