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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
