I just wanted to let you all know about Jim Martens' most recent blog post about the new Designer PCB tools, including an explanation of what sets them apart from other entry-level tools. You can read it here: Designer Schematic and Layout Now Available - Mentor Graphics
His overview includes some information on PartQuest, including the current number of available parts with EDA data (over 350,000!) and some insight into what Mentor envisions for the PartQuest. Keep checking back for more exciting developments on this still-evolving set of tools!
