Exercises
Final test
Slides
 Available on the web
http://lap.epfl.ch/archsoc/
 Mostly available now, but there could be late updates—and
they will be clearly indicated on the web
 No paper copy distributed (if you need them, print lab
documents before coming to the lab sessions!)
 Please avoid printing in colour: slides will be readable in B/W
(if not,
not let me know!)

Board
All labs use the FPGA4U board
 The board is sold for 100 CHF (value ~300 CHF!)
 This gives you the possibility of continuing the labs at home
home—
and of doing many other personal projects, if you so wish

Introduction to the Labs
 Please all come to the first lab session (at least, if you plan on
doing at least one lab this semester…):
20th February
F b
2015,
2015 1pm-3pm

 Interactive tutorial to the FPGA4U board and the tools,
complete system setup with TAs available, test of the lab
submission system, etc.
 Essential for not getting lost in silly problems during the following
labs!
 If you plan to use your laptop, install ModelSim and Quartus II
before the first lab (see http://fpga4u.epfl.ch)
http://fpga4u epfl ch)

Helpdesk and Q&A Forum
 FPGA Helpdesk
 To get your FPGA4U board
Thursdays, 1pm-2pm, INF117
 Q&A Forum
http://moodle.epfl.ch/course/view.php?id=14153
(Help Forum of Moodle, enrolment key ArchSoC_1415)
 Should provide answers to FAQs and a way to get help
efficiently, from both TAs and colleagues

Final Evaluation and Grading
 Labs (every week):
 Automatic evaluation (info during the first lab)
 Deadline (strict!) for submitting lab solutions is midnight of the day
before the start of the next lab (hence, usually one week or two after
the lab started)
 Individual,
Individual hence no identical submissions allowed
 Different weights for the different labs
 Max 20% bonus (= over the average test grade), proportional to the
f
fraction
i off correct llabs
b
 All labs fully correct to get full bonus (= no absences, etc.)
 Final test (4h):
( )
 29th May 2015, 1pm-5pm
 Room INF2-INF3
 Books,

Exercise Book
 Soon to be available on the web
http://lap.epfl.ch/archsoc/
 Mostly, a collection of old exam questions with full
solutions (for almost all exercises)
 If you want to know how well you are prepared for the
tests, do some exercises from there
 Some of the in-class exercises (3-4 sessions) are also
((modified)) exam questions
