Are there the functions 'leEdgeSetLayer' and 'leEdgeAddAll' in skill?

I found the two functions in one skill scripts, but mayn't find them in
documents, even searched out any info with google. Are they exist? If
they're old functions, how to find the replaced ones? Thanks for your help!

In less time than it took for me to respond to this question, anyone
can find out the current status of any of the more than 50,000 SKILL
functions with a single click (including exactly which releases your
functions of interest exist in, whether they are documented &
supported, and if they've been changed or deleted between releases,
and if so, what the arguments are and how to recover from the changes
or deletions, etc.).

1. Bring up the two-part SKILL Survey (CIW: Tools -> SKILL -> Survey)
2. Point to your IL files to create a comprehensive INVENTORY of all
functions called & defined & where located
3. Enter your email address to receive an automated multi-part
detailed analysis by return email

Information you'd find in that survey result would include, for
example, are that leEdgeSetLayer & leEdgeAddAll are both private
(undocumented & unsupported) SKILL functions; available in all
releases (from at least IC440 to IC610); and neither has been changed
nor deleted during at least the past decade.

As you surmised, these are old functions. Interestingly, a quick PCR
search showed that there haven't been any Customer requests (neither
PCRs nor Service Requests) filed for these functions since before 1994
so, they're pretty stable if they are still in use at Customer sites
today.

What you should do, and anyone who feels they need to use an
undocumented unsupported function should do, is file a Service Request
asking Cadence if there are existing public equivalents for these
undocumented unsupported functions. Often there is an existing
replacement. If not, you can ask for them to be considered to be
documented and made public or for equivalent functions to be created
to be documented and supported. I've personally seen over four hundred
of these private-to-public requests successfully resolved when I was
the DFII Marketing Manager and driving the issues (long ago).

EVERYONE ... PLEASE RUN A SKILL SURVEY TODAY and see for yourself the
status of your SKILL functions!
Good luck,

If I remember rightly, these were both "Edge" (aka Artist 2.4) compatibility
functions. Edge was end-of-released back in around 1992 or there abouts.

These were intended to form a migration path from Edge (DF1) to DFII.

I would heartily recommend not using them, and doing the survey as John
suggests.

Andrew.

 

SDA (1986) -> Edge (1988) -> Opus DFII (1990) -> icfb DFII (1995) ->
Virtuoso (2007)

 

Your dates are a bit out - icfb was introduced in 1992 or 1993, but there was
the big change to DFII with the move to 4.4 which came out in 1996 (although the
release was called 9504). The name Virtuoso as a platform appeared in 2003
or 2004, but in terms of the big change (IC610) that appeared in 2006.

Still, this is all a bit academic (and pedantic on my part, sorry).

By no means, Andrew. I think a complete heritage tree of the Cadence
tools with dates and "nicknames" would save a lot of confusion. When
people change companies, the design flow and flow talk changes
abruptly. Some companies don't update as fast as they could, other use
the old naming a long time after it changed (Think of Analog Artist vs
ADE and upcoming ADE-L /ADE-XL /ADE-GXL) I experience that when the
naming of the tools change, the chance that misunderstandings happen
in meetings are big. These misunderstandings lead to fairly off-topic
talk and time is wasted to clear these things out. I once saw such a
diagram for the unix operating system and its derivatives, and it was
really informative. From a marketing point of view it is probably not
so good as the users will then never forget ....

 

Hi Svenn,

When I was DFII Marketing Manager (way back in the 4.4.x Y2K days), in
addition to a newsletter for each release, I used to post the
following release-cycle information on Sourcelink:
* DFII Release Life Cycle Overview
* DFII Release Life Cycle Matrix
* DFII Release Life Cycle Questions

I just checked and the DFII Four Four Forum Customer newsletter is
still there ...
http://sourcelink.cadence.com/docs/files/FFF/welcome.html

But the release-cycle information seems to be a dead link.

You might want to ask Customer Support to generate new release cycle
information so all benefit:
sda --> opus --> icfb --> virtuoso

Good luck,
John Gianni
