Predefined Ports in Virtuoso

Hello,

i have a question regarding the predefined ports in virtuoso. I noticed that stdout and poport are equal, so what is the difference between stdin and piport?

My guess is that piport is linked to that "what you write in the CIW", whereas stdin is the "default" UNIX stdin !?

If so, is it possible to redirect stdin to piport?

Thanks in advance.

Best regards,

Matthias

Matthias,

stdin is the stdin of virtuoso (i.e. the terminal window) whereas piport is the CIW input. You can reassign stdin=piport if you really want.

However, reading from either stdin or piport is a fairly unusual (and probably not recommended) thing to do with Virtuoso.

Andrew.

Andrew,

I came across this post in the cadence community forum today, in which a second Virtuoso instance is created as a child process. Referring to the question above:

If I create a Virtuoso Child process using

cid = ipcBeginProcess("virtuoso -nograph")

and I send a skill command to the child process

ipcWriteProcess(cid "file=outfile(\"myFile.txt\") fprintf(file \"Hello\") close(file)")

the file wont't will be created. Is it possible to send a skill command to the child process, apart from the -replay parameter ?

Many thanks.

Best reagards,

Matthias

Matthias,

This is just because you haven't ended the line sent to the process with a carriage return, so it's still waiting for the input line to be completed. If you do:

ipcWriteProcess(cid "file=outfile(\"myFile.txt\") fprintf(file \"Hello\") close(file)\n")

Then it will work.

Regards,

Andrew.
