Mentor Graphics Corporation announced the first phase of the new Xpedition printed circuit design (PCB) flow to address the increasing complexity of today's advanced systems designs. The increasing densities of electronics products are forcing companies to develop highly compact system designs with more functionality, and at lower costs. To efficiently manage the density and performance requirements for advanced PCB systems, the new Xpedition flow provides advanced technologies to enable design and verification of 3D rigid-flex structures, and to automate layout of high-speed topologies with advanced constraints.
