Set UNIX environment variable through in Cadence environment through skill

rajs

Cadence version using=IC616.

Hi ,

I have two questions which i have listed below

a)Not able to set PVDIR variable in unix through skill command.

system("setenv PVDIR /home/data/")

error message in unix terminal: sh: setenv: command not found

b)I want to streamout the gds and then execute skill code sequentially, if the error not exist in streamout or else terminate with error message.

   1)How to wait till streamout is done & How to check for error message. There is a user defined function "xstOutOnCompletion()", How to use 

         along with procedure.

envSetVal("xstream" "xstShowCompletionMsgBox" 'boolean nil)

xstSetField("library" libname)
xstSetField("topCell" cellname)
xstSetField("strmFile" strcat(cellname ".gds"))
xstSetField("attachTechFileOfLib" "tsmc90_tech")
xstSetField("view" "layout")
xstSetField("runDir" path)
xstSetField("summaryFile" "strmOut.sum")
xstSetField("virtualMemory" "true")
xstSetField("logFile" "strmOut.log")
xstOutDoTranslate()

 

Thanks,

rajs

    The first approach wouldn't work for two reasons. First of all "setenv" is a "csh" command, not a "sh" command. Anyway, even if that had worked or you'd use an appropriate command ("export VAR=value", say), then this would not have helped because it environment variables are only inherited in child processes, not in the parent process. What you want to use is setShellEnvVar("VAR=value").

    The documentation explains how to write xstOutOnCompletion - and even gives an example. You don't wait for it to return - instead, you have a callback that is triggered when it completes and this callback receives the status information. You can then do any subsequent actions  you need from within your xstOutOnCompletion definition.

    Regards,

    Andrew.
