Greyed menu: "Run Assura Quantus QRC..." and "Run Assura Quantus QRC..."

Have you run LVS? If yes, which tool did you use? If you ran LVS using Assura, can you tell me the IC and Assura versions you are using.

Regards,

Saloni

Yes, LVS passed without any problem.

I am using IC617, ASSURA41 and EXT172.

Can you post a picture of both the Assura pulldown menu contents

Thanks for the QRC pulldown menu - could you also post the Assura pulldown menu contents too as I requested. So far nothing looking too unusual and I can't see see too much why this wouldn't work.

You may need to contact customer support if we can't get to this simply.

Regards,

Andrew.

Oh sorry Andrew

Here is the assura pulldown menu:

Thanks - that’s useful evidence as now I can peel another layer off the onion and hopefully figure out the root cause (the QRC menu item is greyed out because of a missing item in the Assura menu; just need to determine why that is missing). Hopefully I’ll be able to look later today.

I discovered one more interesting thing.

There are 3 directories in "<cds_install_path>/EXT181/tools/extraction/bin/64bit": 5.1.0, 6.1.0, 6.1.7

I deleted 6.1.0 directory. When I did that, QRC menu didn't appear in my layout window.

So, I think that the problem is that the context menu is loaded from the wrong directory, 6.1.0 instead of 6.1.7.

I don’t think that’s the reason. I suspect you’ve just disturbed a pre-check by doing this. 

Am I right in thinking that you’ve also opened a case with customer support on this? I want to avoid duplication of work...

Regards,

Andrew

The path I put in the previous message was wrong. The directories are in "<cds_install_path>/EXT181/tools/extraction/bin/64bit/etc/context"

Really Andrew, I think it could be the reason yet, because I made another try. I removed the 6.1.7 directory. And the QRC menu appeared normally. So, the layout editor is loading context menu from 6.1.0 directory instead of 6.1.7.

I opened a case with customer support but I didn't have any solution until now. And the support don't want to help because I am working on CentOS instead of RedHat. So, this forum is my ultimate hope. My university make an effort to pay Cadence license. CentOS is equivalent to RedHat and always worked fine for us until now.

I'm sure this is nothing to do with CentOS. Also, having checked, the 6.1.0 is always loaded even in my case (the code doesn't appear to load the 6.1.7 directory - so that's not the reason here).

The reason why the QRC->Run Assura Quantus QRC menu is greyed out is because you don't have Assura->Run Quantus QRC in your menus (it should be between ERC Browser and Close Run). 

I can't really see why this isn't working - I've traced through the code a lot, but the only place I can see where the menu is missing in the Assura menu is when it doesn't find QRC, and because Assura RCX is EOL, it removes the menu item.

Can you check the return value of each of these:

getShellEnvVar("QRC_HOME")
getShellEnvVar("QRC_ENABLE_EXTRACTION")

then try this:

tracev(qrcUI_Ok)
trace(_vuiIsQrcMenuAvailable _vuiIsRcxMenuAvailable)

before you start the layout editor for the first time in a session, and post the section of the CDS.log (or what you see in the CIW) when you open the layout - there should be some trace messages (I'm assuming that as a University you have the SKILL Development product).

Regards,

Andrew.

Here are the results (I also tried to enable QRC_ENABLE_EXTRACTION in another session but it didn't work):

INFO: Adding Quantus QRC SND Analysis into Assura Menu

Thanks for the extra info. That was helpful.

From this I've figured out what is wrong (hopefully it's what I think it is). I think you have $QRC_HOME set, but do not have "qrc" in the UNIX path before you start virtuoso. If I do that, then I see exactly the same symptoms as you (no Assura->Run Quantus QRC menu, and the QRC->Run Assura - Quantus QRC is greyed out). In the terminal, check if:

echo $PATH

contains the path to $QRC_HOME/bin. Also see what "which qrc"  returns, and what "qrc -v" returns in the terminal window.

Finally, check what _vuiGetQRCVersion() returns in the CIW.

Regards,

Andrew.

Unfortunately, I think the problem is other. It all seems to be normal.

Thanks. You didn't say what _vuiGetQRCVersion() returns - can you show that (you'll have had to have opened a layout window first)?

Also, can you provide what these output (both in the CIW)?

_vuiGetQRCContext()

system.??

In the terminal window, can  you  run "cds_plat" and post what is returned?

Thanks,

Andrew.

Sorry Andrew, I forgot. Here are the results:

_vuiGetQRCVersion()
*Error* eval: undefined function - _vuiGetQRCVersion

system.??
(name "Linux" plat "lnx86" dirBrkChrs
    "/" dirSepChr "/" pathSep ":"
    shLibExt ".so" LP64 t P64
    t
)

[bit@cds TSMC-CR018]$ cds_plat
lnx86

You need to do it after opening a layout window (so that Assura has initialised - I said that before). So I need that and both the _vui function output including _vuiGetQRCContext()

Andrew

OK, sorry again. I have to pay more attention.

_vuiGetQRCVersion()
0
_vuiGetQRCContext()
"/opt/cadence/EXT181/tools.lnx86/extraction/bin/64bit/etc/context/6.1.0/64bit/qrc.cxt"

OK, we’re getting close. The first returning 0 is why the menus get messed up. Now just need to figure out why it returns 0.

I’m on a plane now so this will need to wait until a bit later to debug further. 

To be honest, doing this via the forums is not the most efficient way of solving this - thanks for your patience. 

Andrew

OK Andrew. It's I who thank you.

I know it is a bit frustrating to have to wait for the return of a simple command.

Thanks again,

wighou

wighou,

I thought I'd found a possible explanation, but I'm not convinced this can be it because if I mess with this the QRC menu doesn't appear at all and I get some different warnings in the CIW. Anyway, just in case, can you open the layout window as before and then do:

rexMagic()

I'm interested if this returns nil. If it does, try:

rexMagic(t)
_vuiGetQRCVersion()

and see if that returns something other than zero. Otherwise, try doing this:

trace(_vuiGetQRCVersion _vuiEvalQRCVersion)
tracev(qrcVer version qrcOk)
_vuiGetQRCVersion()

and paste here what you get.

Thanks,

Andrew.

I had a problem of moderation I think. I will begin with this first part:

rexMagic()
t

trace(_vuiGetQRCVersion _vuiEvalQRCVersion)
_vuiEvalQRCVersion(_vuiGetQRCVersion)

tracev(qrcVer version qrcOk)
|[1]qrcVer set to unbound, was unbound
|[1]version set to unbound, was unbound
|[1]qrcOk set to unbound, was unbound
(qrcOk version qrcVer)

and the second part (_vuiGetQRCVersion() response), you can find here: https://file.io/NGbhKi

I just get a "file.io 404 Page not found" error if I try to follow that link. Can you not attach it as a text file here if it won't let you paste it? If it goes into moderation, I can approve it - although I've not seen anything that needs approval. Use the Insert->Image/video/file below...

Regards,

Andrew.
