Memory layout can get boring after a while, but it will expose
you to a very different set of interests and methods. For one,
memory layout is about maximal cheating and challenging of
groundrules (which in the end I see often results in "special"
memory groundrules, but this is preceded by you, the layout
designer, identifying the rules-binds that hamper layout
compaction and then chest-bumping the process, device and
reliability referees until you work out a barely engineering-sound,
barely-market-viable (this year) compromise).
I wouldn't want to spend my life doing memory layout but it
is not a bad thing to be able to say you understand and have
done, what with Inevitable Integration of Everything being
the guiding star of the industry. Just move on from it before
the cement sets around your ankles.
