I want to learn more about what is required for a chip outside just putting a design on the user project area. Are there any good guides on things like esd protection, padrings, power, packaging, etc?
I am just seeing that Weste and Harris has a chapter on these things, but I am also looking for something more practical and applied.

Each of these topics that you have listed are specialities on their own that companies usually have dedicated teams for each: - Chip packaging - I/O Pads (including esd) - Power delivery (PDN) In addition to this, the RF, Analog & mixed signal blocks (like PLLs, temp sensors etc.) would also be handled by a separate team Also, Chip packaging and PDN come under the SI-PI (Signal Integrity, Power Integrity) domains and are somewhat identical to PCB design in terms of the basic principles. It would be better if you search for separate books for each of these. But I am not sure if there are graduate textbooks that deal with these on a step-by-step detailed application basis I guess, someone who has worked on this hands-on would be able to provide a more detailed answer.
--- Some books that explain the theoretical side (if it is of any help): Signal & Power Integrity: 1. Signal and Power Integrity Simplified - Eric Bogatin 2. Understanding Signal Integrity - Stephen C. Thierauf 3. High-Speed Digital System Design - A Handbook of Interconnect Theory and Design Practices - Stephen H. Hall et. al. 4. Power Integrity Modeling and Design - Madhavan Swaminathan Additionally, packaging needs to take care of the thermal and mechanical aspects also. So there's that as well... IO Pads and Pad macros generally come under the analog & mixed signal category. But the padring and pad macro placement is done by the floorplanning/ backend pd teams.
