Objective

The hidden motive: To entice you to participate in
the Controlnet internal workshop

At the end of this talk, you should be in a
position to appreciate what formal writing
style is, and how formal paper
presentations are made.

Literature Survey

Brief description of the existing body of work

Citations to published work


In
[2],
Rosetti and Longfellow described the meaning of
life. Wordsworth presented a different view point in

Bring out the specific advantage of your work
w.r.t. published work.


However, the Rosetti

Longfellow formula [2] fails for
technologies below 0.2 micron. In this paper, we extend
their formula to the deep submicron domain.

The “Conclusions” Section

State what was achieved in the paper

Were you able to come to some definite
conclusions?


We presented two algorithms, A1 and A2, for the
floorplanning problem. Our experimental results
indicate that A1 outperforms A2 in terms of solution
quality, but requires about 100% more time than A2 in
most cases.

Be frank about the limitations of your work

Point out directions for further work

Writing Style

Use simple sentences, unless you are comfortable
writing complex and compound sentences

Avoid repetition

Make use of the grammar and spelling checker,
but exercise caution

Will a figure or table be able to say the same thing
more effectively?
