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.

As of this morning I see 670 models listed in the repository.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
