I see the same thing with PCB layout tools and the associated schematic capture tool libraries! Every time I start a project I have to weight the cost of using existing models (footprint/schematic) against possibly better parts (or lower cost) and extensive library model development. What ever happened to IC vendors supplying models for their components to the software houses? It adds cost and delays schedules for every new part/package, couldn't the industry ask for standard parts to come with these models? Imagine the savings in time!
My experience in an internal corporate CAD/EDA group parallels yours, Brian! Our collegial customers demanded certain models, and we had to relay those demands to Mentor Graphics, Cadence, Synopsys and various EDA SME's, etc.
As for TLM Central, I will investigate it but from the description here, it reminds me a lot of Design-Reuse from France.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
