How could I make my PV GUI communicate with Virtuoso through port so gds export has no issue

mctang

Hi 

I try to use “pipo strmout out.tmpl” in batch mode to export gds, which is invoked by my PV runtime GUI. However, I get the following error

message. Internal virtuoso wrapper script defines environment VARIABLES which cannot be recognized by batch-mode pipo/strmout

 

Reading Cadence database ...

*WARNING* '/mrvl2/tcad10s/pganl4/pganl4/wa/mctang/CALIBRE_SUPPORT/backup/cadence/skill/CODE_EXAMPLE/menu_runtime/workdir/cds.lib', Line 1: Cannot find file '/proj/cdspdk/tsmc/t16nm/CRN16FF+LL_LOGIC/$FOUNDRY_PDK_VERSION/PDK_ic61/1P11M_2Xa1Xd_h_3Xe_vhv_2Y2R/cds.lib'.

FATAL (4): Failed to open the technology file `techfile.cds' from library `test_sch'. Check that the library exists in the location defined in the 'cds.lib' file and that you have read permission to the technology file.

 

I would like to send the command from my PV runtime GUI directly to Virtuoso through port. I could implement this feature in another layout tool.

If I use “FILE-> Export”  from CIW, the following command is executed and  there is no gds export  issue. Could you show me how to implement in Cadence Virtuoso ?

strmout -library 'test_sch' -strmFile 'PLL_A.gds' -techLib 'tsmcN16' -topCell 'PLL_A' -view 'layout' -logFile 'strmOut.log' -enableColoring Virtuoso Framework License (111) was checked out successfully. Total checkout time was 0.05s.

Thanks,

    Hi Andrew,

    Thank you for your help. PIPO should not be used for IC61X. I will encounter the same problem if I use "strmout".

    The error message is due to

    envVars in Unix are not evaluated when calling strmout in batch mode. It seems that batch mode strmout does not read .cdsinit and thus the envVar(s) to point to foundry techfile do not get loaded.

    I am currently using "system(strmout xxx   &)" command in my perl script. I am not sure ipc command can fix the above problem (missing environment variable)

    Thanks,

    ManChak
