Some question on SKILL

Hi all,

I am new to SKILL and is trying to write some procedures to automate
some task in virtuso. I would appreciate if someone can help me get
started.

1. Is there a proper documentation of all the defined functions? The
only place where I can get some information was only the finder in the
SKILL development

2. A few technical question.
I got a db object using the following

net=dbFindNetByName (deGetEditCellView) "q_net<0>"

I don't seem to get any result from
dbGetPropByName net "name" => nil

but this is okay
net->name => q_net<0>

3. Last, is there a way to list out the propert name for a db object? I
need to know the keys to get the values.....

Thanks
shuteng

 

Which indeed is the first place that you should start when looking for
a function that you don't know if it exist or not. By use of the
finder, you find the potential function names. Then you either go to
the online documentation and use the search function on the selected
functions of interest, or you copy all the pdf documents in the
documentation part of the cadence installation to a folder and let one
of these desktop search tools (beagle, copernic, google) index that
directory for you. If you use windows or KDE, you can use the folder
search function to look for the function name as a full text search on
that directory. You can also have acrobat reader do a fulltext search
on all pdf files in a directory and last but not least, you can use
Sourcelink to find it.

 

Hi shuteng, it might be that you are confusing nets and signals.
It might be that you have named q_net<7:0> and signals q_net<7>,
q_net<6>, ... q_net<0>. If that is the case dbFindNetByName
will not find it. But there is no such net. If you want to find a
signal
by name, there are many possibilities. If performance is not
important
you might try something like the following

(defun find_net_with_signal (cv sigName)
(car (exists net cv~>nets
(exists signal net~>signals
(equal sigName signal~>name)))))

This function will return some net which has a signal with the given
name.
E.g., you might have two different nets, one named q_net<7:0> and
another
named q_net<127:0> which both have the signal named q_net<0>.
This function will return one net or the other. If you want to find
all such nets
and not just the first such one, change it to the following.

(defun find_nets_with_signal (cv sigName)
(setof net cv~>nets
(exists signal net~>signals
(equal sigName signal~>name))))

Does this help?

Thanks for the tip on using Finder, it works well. I accessed it via
the CIW window: Tools~> Skill Development and then from the Skill
Development menu: Finder...
