The Designer's Guide Community Forum is a place where integrated circuit designers
help each other. Everyone on the forum is donating
their time and expertise. As such, everyone on the
forum should be treated with courtesy and respect.
To make the forum run as smoothly as possible,
please follow the guidelines given below.
Things to Avoid
Do not post the same message in multiple boards.
Do not post simulation or CAD tool questions in
the design boards.
Do not solicit help from individual members
through the private messaging system or through
email addresses that are made available from
this site. Instead, all requests for help should
be made to the community through postings on the
Create your own topic. Do not jump into another
person's topic. This only creates confusion and
makes the board harder to search. Even if the
problem seems similar to you, more often than
not, the answer to your request will be
something different from the original posters.
Do not attach copyrighted material to your posts
unless you own the copyright. By posting
copyrighted material to this website, you affirm
that you own the copyright and you are giving
The Designer's Guide Community perpetual license to share that material
on the open web in accordance with its license
agreement, as given on the Submissions page.
Post job openings only on the Opportunities board.
All other solicitations will be immediately removed.
Do not send the same or similar unsolicited
private messages to more than one or two
Do not post commercial messages or
advertisements. Posts can mention products, but
the intent of the post should be to educate
rather than promote. The converse is also true.
Do not bash CAD tools or vendors. Constructive
criticism is welcome, but not blanket criticism.
Do not post links for purpose of advertising and
do not include links that do not support the
mission of the site, that of educating analog
engineers. Doing so will result in your post
and your account being deleted. Such links are
forbidden everywhere, including in your profile.
Do not use foul language or post graphic images.
Check to see whether your question has been
answered previously. When searching, search all
appropriate boards and set the 'This post was
made in the last...' field to '(all posts)'.
Carefully consider the most appropriate board
for your post. Post you message in only one
board. In particular, ask simulation questions
on the simulation boards, not on the design
If you are unable to find your answers by
searching the boards, or if the answer was
incomplete or not quite correct for your
situation, feel free to post your question
on the forum. Please follow these
Limit a thread to a single topic, and
preferably to a single question or small
number of very closely related questions.
Doing so makes the threads easier to follow.
Try to ask specific and bounded questions.
You are much more likely to get a response.
Use a descriptive subject line, and format
Make sure you include the relevant data in
your help request. Usually, the more
accurate information, the better we can help
you. However, also try to be succinct. Fewer
people read long posts.
Acknowledge peoples responses to your posts
and let them know how their suggestions
worked out for you.
Write carefully and clearly. Do not use
instant messaging short hand. Define the
meaning of obscure terms and acronyms.
Remember that you are writing to a general
audience. Using highly specialized
terminology without explanation will greatly
limit the number of people who can respond
to your question.
Please remember that this forum is a general resource
for everyone. As such, you should try to ask your
questions in a way that everyone benefits from the
answer. In that spirit, if you have a question or
comment about a model, you should include the model here
or give a pointer to where it is publicly available. If
you ask about proprietary models that many visitors do
not have access to, then you limit the number of people
that can answer your question and the number that
benefit from a response. If you really need to ask a
question about a proprietary model, try to develop an
abstract or alternate version that exhibits the same
behavior and use that to ask your question.
If you are seeking help on a problem you are having with
a particular tool, give specifics (netlists, models,
outputs, error messages, etc.) so that others can
identify, and perhaps even reproduce, the problem.
If you are asking for help, describe what you have
already tried. People are more likely to try to help
those that are trying to help themselves.
Be considerate and tolerant. Rudeness will not be tolerated.
