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 ...

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,

    This doesn't make any sense. Sure enough, strmout doesn't read the .cdsinit but I don't see what that has to do with strmout not evaluating envVars - the environment variables would be evaluated by the shell used to invoke the strmout command anyway, so that would work.

    Having seen an internal email, it looks to me as if you're also asking questions via customer support (case 45957207). Please don't ask both in the forums and customer support (unless you're directed to customer support from here) because it just duplicates effort and nobody knows who is doing what.

    So my assumption (consistent with what I've seen by the case in question in the internal discussion) is that this is just you doing something incorrectly and there's really not enough in the thread above to be able to help you out. I suggest you continue working through the case instead.

    Kind Regards,

    Andrew,
