Display packet information 'display' not found.

Which foundry pdk are you using?

Display packet information is defined in the display.drf file supplied with the pdk. Typically this is loaded in the libInit.il file in the process techlib directory. If a copy exists int he workarea this will be used.

 RobMan , Thank you for the response ..  i am using tsmc65 and recently installed it. i don't know where the problem occurs

Dear RobMan , yes i have  dispay.drf file in techfile folder. but where i have to copy it. can you please tell me ??

A quick fix would be to copy it to your working directory.

TSMC typically use libInit.il to load. Look in <PDKpath>/tsmcN65/libInit.il. Search for display.drf and check it's loaded.

RobMan , when i checked liblnit.il , this content is writtten in the file .

    ;Load display file ----------------------------------------------------------------------
    filePath = sprintf(nil "%s/display.drf" getWorkingDir())
    if( isFile( filePath) then
       printf("Loading Working place Display File '%s'\n" filePath)
    else
       filePath = sprintf(nil "%s/../display.drf" libPath)
       when( isFile(filePath)
           when( isCallable( 'drLoadDrf)
               printf("Loading PDK Display File '%s'\n" filePath)
               drLoadDrf(filePath)
      );when(drLoadDrf)
    );when(isFile)
    );if(isFile)

Yes, so this loads the display.drf from the working directory or the directory above the library path.

If the display.drf is loaded and you still get errors then the techlib and display information are potentially out of sync. i.e. Layers have been added to the techlib but no corresponding update to the display information. Any undefined layers will appear yellow on the canvas.

RobMan  , Yes the above error is removed after copying the display.drf file in my working directory . However when i try to do "generate from source" i got the error "pcell evaluation failed". Please suggest how to rectify this problem.

thank  you

This sounds as if something is seriously messed up with the PDK installation. It sounds as if it's (maybe) not loading the context files containing the underlying functions used within the PCell. This might be the same reason that the display.drf isn't loaded.

Have you by any chance renamed the tsmcN65 library? There is code in the libInit.il that assumes the library is called tsmcN65 and if you've named it something else for some reason, this will fail to work.

Debugging a "pcell evaluation failed" error without an indication of the actual error is rather hard, but this is definitely not normal.

I suggest you contact ASK (customer support) by logging in at http://support.cadence.com and then using the Case menu to submit a support case.

Dear Andrew Beckett , Thank you for the response but i have not renamed tsmcN65 library.

If you start a fresh virtuoso session, and then in the library manager you click on the tsmcN65 library (maybe right mouse->properties) do you get something like this in the CIW:

Initializing from libInit.il for library tsmcN65...
-- tsmcN65_updateCDFs.il
-- amsNetlister.ile
-- tsAbutFunction_cdn.ile
-- tsmc_esti.ile
-- pnp.cbe
-- npn.cbe
-- npn_mis.cbe
-- pnp_mis.cbe
-- tsmcN65Tool.cxt
-- tif_tcf_crn65lp_v1.2a_patchA.cxt
-- tsmcN65.cxt

(this is from a very old tsmcN65 PDK I happened to have locally). 

As I said, contacting customer support is almost certainly the best choice here - it's very hard to debug odd things like this over a forum.

Andrew

Dear Andrew Beckett , actually i cannot take cadence support  help due to non availability of HOST ID. However when i have click on properties . i got

Does that file exist and do you have the permissions to read it? I'm pretty certain it must exist since the libInit.il in TSMC PDKs usually just use a getDirFiles() to determine what to load, but maybe there's an issue with the permissions.

Looking back, I wonder whether the display.drf within the PDK didn't get used because there's already one in the working directory (that takes priority from the code you mentioned earlier). My (old) copy of the tsmcN65 library (maybe a different process variant anyway) doesn't contain that code, but if it looks like you showed, the working dir's display.drf would win.

Andrew

Andrew Beckett yes i have an access to the root  and have permission to the files

Can you please do this in a terminal window and report the results:

ls -l /home/MSRF_Low_Power/PDK/Cadence_OA/tn65cmsp007k3_1_7a/tsmcN65/../skill/64bit/tsmcN65Tool.cxt
ls -l /home/MSRF_Low_Power/PDK/Cadence_OA/tn65cmsp007k3_1_7a/tsmcN65/../skill/tsmcN65Tool.cxt

Thanks

Andrew
