Cadence schematic showing up all as yellow

Paste this code into the CIW (or put in a file and do load("abDebugPacket.il") to load it):

/**************************************************************************
*                                                                         *
*          abDebugPacket(layer purpose @key (display "display")           *
*                                                                         *
* Code for debugging what packet is associated with a given layer purpose *
*                                                                         *
**************************************************************************/

procedure(abDebugPacket(layer purpose @key (display "display")
        (cv geGetEditCellView()) "tttd")
    let((tf lp packetName packet)
        tf=techGetTechFile(cv)
        lp=tf && techGetLP(tf list(layer purpose))
        packetName=lp && techGetLPPacketName(lp)
        packet=packetName && drGetPacket(display packetName)
        printf("%s %s : %L %L\n" layer purpose packetName packet)
    )
)

Then type these three lines and post what you are getting (make sure the schematic window is the current window when you do this):

abDebugPacket("wire" "drawing")
abDebugPacket("device" "drawing")
abDebugPacket("pin" "drawing")

Thanks. This may help me to understand what's wrong.

Hello dear Andrew,

I have the same problem with Cadence 6.1.6. I have done your instruction but nothing is changed. Do you know what he problem is?

Thanks!

No, because you didn't post what the output was. In my response in the thread I said:

So can you do that? Then I might be able to understand what is going wrong.

Thank you for your reply, a snap shot is attached.

OK, based on the packet names, that looks as if you must be using a schematic in a library attached to a TSMC PDK technology library. They renamed the packets used to be similar to those you're showing.

So, what I would suggest is checking the name of the attached technology library:

techGetTechFile(geGetEditCellView())->libName

and then in the library manager, go to that library name and use Right Mouse->Properties. Look for the readPath and then in UNIX take a look in that directory (and most likely the one above it) to see if there's a display.drf. That's almost certainly got the packet definitions you need.

What is odd is that this would normally get automatically loaded by the libInit.il file within the technology library - but maybe something has been changed in your environment. You probably could just copy the display.drf you find into your working directory and restart Virtuoso and see if that helps?

Thank you for the solution, I don`t know what the problem exactly was but I could fix it by Tools->Display Resources Manager->Merge... from the icfb menu.

Hi Fariborzlp,

Could you please explain what files you merged. I am having the same issue that you had. I tried the Merge option but, I am not sure what to select in the options attached below

It rather depends on what technology you're using - can you give a bit more info? The picture you posted (better to load the image in the post directly rather than elsewhere, but never mind) only showed a couple of Cadence-provided libraries - most likely you're going to have to locate the display.drf on your system somewhere. Usually most PDKs come with a display.drf and usually that would be auto-loaded when that library is used so you might need to look for a file somewhere wherever the PDK is installed.

You may not need to merge it - you may just need to load it with Tools->Display Resource Manager, then Edit, the File->Load and navigate to the location of the display.drf.

If you know the PDK you're using, we might be able to give you some insight as to where it is likely to be.

Hi Andrew,

Thank you for your response! I am using TSMC 180nm. I still couldn't find the display.drf on the system.  I would appreciate it, if you give me some insight to where I will likely find the display.drf if that's possible.
