Error on invoking Skill IDE

Saurabh,

Which sub-version of Virtuoso are you running? - getVersion(t) will return that.

Also, can you repeat the problem and then type where() or stacktrace() at the prompt to show where it is failing? I've had a quick look in current versions and can't see how it could fail this way, and I've not found any reports of the same issue. I can think of a potential workaround to solve this, but I'd like to understand first how this could happen to figure out whether that workaround stands any chance of working or not.

Andrew.

Hi Saurabh,

Have you tried to launch it through the corresponding Skill commad:

_ilgRunSkillIde()

Hi Andrew

I am using the following sub-version: "sub-version  IC6.1.8-64b.500.10 "

I used the where () command and got the following output.

As mentioned by Mbracht,  If I use the _ilgRunSkillIde() command in ciw, then I don't get any error.

Saurabh,

It seems that the issue is caused by a preference setting in ~/.cadence/skill_ide_hi - it's to do if you have previously used a case insensitive search in the profiler. The line is:

isCallable('_ilgSetProfilerOptions) && _ilgSetProfilerOptions("Run Time" t t 1000 0.0 0 "" "" "")

(its the second t). However, this should be fine, because normally the profiler window has been created before the preference file is loaded, so the callback for the case-insensitive search option (which causes this failure) would then succeed. From what I can see, _ilgRunSkillIde() will always create the profiler window first, so it shouldn't fail.

What is odd is that it works when you run this function - because _ilgRunSkillIde is what should be called when you run Tools->SKILL IDE in the CIW. Could you do the following?

1. Turn on the "a" choice (Accelerated Input) in Options->Log Filter in the CIW
2. Use Tools->SKILL IDE and see what function was invoked when you did that?
3. In the CIW type ddGetStartup("menus/ciw.menus") and report what it returns

Thanks,

Andrew.

Hi Andrew

After setting the  "a" choice (Accelerated Input) in Options->Log Filter in the CIW, I invoke the skill IDE using Tools->SKILL IDE. Below is the output in the CIW.

hiSetFilter()
hiiSetCurrentForm('hiSetFilterForm)
hiSetFilterForm->accelInput->value= t
hiFormDone(hiSetFilterForm)
_ilgRunSkillIde()
Loading skillide.cxt
Loading skillDev.cxt
*** Error in routine eval:
Message: *Error* eval: unbound variable - __ilgProfilerWindow
Entering new debug toplevel due to error:
Type (help "debug") for a list of commands or debugQuit to exit the toplevel.
_ilgSetFocus(4)

I run the ddGetStartup("menus/ciw.menus") in the ciw, I get the "nil" as output. (I run this command just after invoking skill IDE.)

Thanks and Regards

Saurabh

Saurabh,

OK, so it's just calling the same function, and you don't have some old customised ciw menus - that was my guess as to what the issue might have been. Clearly not that then!

I've just realised what causes this though, and can reproduce it. I also know how to solve it.

To fix

1. Launch the IDE (it will give the error above)
2. Close the IDE
3. Launch the IDE again in the same session and change the workspace choice from "Skill IDE" (or whatever it was) to "Checking" (either via the toolbar or Window->Workspaces->Checking) so that the profiler docked window appears
4. Hit the green button on the profiler, and then hit the red button to stop it
5. Click on the "Profiler Options" icon (to the right of the Search box in the profiler) and turn off "Case Sensitive Search"
6. You can change the workspace to something else again now (e.g. "Coding")
7. Close the IDE

Now if you quit Virtuoso, and restart, the problem will be gone. You can also solve it by deleting the ~/.cadence/skill_ide_hi file (that will lose your other preferences and file history though, so it's up to you whether you want to do that).

The issue is caused by running the profiler, turning on case-sensitive search, and then changing the workspace to something that doesn't show the profiler window. The callback for the case sensitive search is applied when the preferences are loaded, and that assumes that the profiler is present, but if the preferences indicate that the last window configuration didn't contain the profiler, the profiler window hasn't been created at that point.

Bit of a tricky one! I'll file a CCR (change request) to get this fixed.

Andrew.

Hi Andrew

Thanks for your quick reply. After following the steps you mentioned, I am not getting the error anymore.

Thanks and Regards

Saurabh

Hi Saurabh,

Glad that solved the issue. I filed CCR 2319205 to get this fixed.

Regards,

Andrew.
