Using Virtuoso schematic editor 5.10.41, I am running script to correct some transistor properties like LOD and diffusion area props by loading script into CIW. During that script, at ICFB window I have some warning mesages (like warning messages when we are generating netlist if the port order is not matched etc).
Do you know how to reach whole list of warning message or to save into an output file since CIW shows a limited of them and overwrites the old ones with new ones after some point.
Well, they all go to the CDS.log regardless - they don't overwrite - but the CIW only shows a finite length of the filtered log.
You can also get it to start replicating to a different place (as well as the CDS.log) using hiStartLog() and hiEndLog() - see the documentation for details.
You could also use one of these two SKILL++ approaches. Note that these examples are redirecting "poport" (which is the normal output). If you wanted to redirect warnings, you'd need to alter them to redirect "woport" instead of "poport" (woport is the port for warnings):

Defines two functions abPoPortPush(port) and abPoPortPop()
which allow the current poport to be replaced by a new value,
and restored afterwards. Implemented internally as a stack,
so the calls can be nested.
This is SKILL++ code, so must keep the .ils extension
SCCS Info: @(#) abPoPortPush.ils 01/20/99.08:23:43 1.1
/* make the normal output port accessible */
/* predeclare exported functions - don't have to do this really */
(define abPoPortPush nil)
(define abPoPortPop nil)
(defun portPush (port)
(setq portStack (cons poport portStack))
(setq poport port)
(defun portPop ()
(setq poport (prog1 (car portStack)
(setq portStack (cdr portStack))))
/* export the functions */
(setq abPoPortPush portPush)
(setq abPoPortPop portPop)

Call using abRedirectOutput(t) or abRedirectOutput(nil)
to turn printing to CIW on or off.
Note, this is SKILL++, so requires file to end in .ils
SCCS Info: @(#) abRedirectOutput.ils 12/22/11.11:08:13 1.3
/* going to define abRedirectOutput */
(define abRedirectOutput nil)
/* private variable containing port to /dev/null */
(procedure (redirect on)
(setq nullport (outfile "/dev/null")))
(setq poport nullport)
(setq poport (inSkill stdout))
(setq nullport nil)
/* export it */
(setq abRedirectOutput redirect)
In reply to Andrew Beckett:
Again, thanks for your prompt response as always. I think I will use woport Skill++ function. I need to load this function before my scrip, do I? For the documentation you mentioned ("see the documentation"), do you mean Cadence® User Interface SKILL Functions Reference?
In reply to yayla:
Both cdnshelp and cdsdoc provide search capabilities, but yes, those are in that manual.
