Getting started page references module Period that does not exist?

[newdimm]

Hello,

I struggle to run the first example (up_counter.py) from the Getting Started tutorial here:
https://amaranth-lang.org/docs/amaranth/latest/start.html
It tries to import module Period from amaranth.sim which does not seem to exist:

(dpython) dimm@dimm-nux:~/Downloads$ python3 up_counter.py
Traceback (most recent call last):
File "/home/dimm/Downloads/up_counter.py", line 46, in
from amaranth.sim import Simulator, Period
ImportError: cannot import name 'Period' from 'amaranth.sim' (/home/dimm/dpython/lib/python3.12/site-packages/amaranth/sim/init.py)

Does it need updating or is it that I'm doing something wrong?

Many thanks,
Dmitrii

https://amaranth-lang.org/docs/amaranth/latest/start.html points to the documentation of the (latest) development version. Currently this is 0.6.0.dev77. The latest released version currently is 0.5.4, and that does not have Period. So you either need to update amaranth, or you can look at the documentation for the version that you are actually using. For example for 0.5.4 this would be https://amaranth-lang.org/docs/amaranth/v0.5.4/

Indeed, once updated to the development version all is good. Thank you for helping! :-)
