I created three 555 timer symbols (same .subckt, behavorial model) in Qspice environment. You can find in this link, in sub-folder 555Timer. It contains a pdf explains the circuit and examples compare to TI datasheet.

Great work!
By the way, “The Story of 555” is in Hans Camenzind’s book, “Designing Analog Chips”.
The book can be downloaded from http://www.designinganalogchips.com/.
Although Mr. Camenzind has passed away, his website continues to be accessible.
