Run a shell command through ipc in a specified directory

Hi Martin,

As long as you are running shell commands, why don't you just do a cd command before the si one ?

ipcBeginProcess("cd ~/simulation ; si -cdslib cds.lib -batch -command netlist > si.log" )

Cheers,

Aurel

Or simpler still, just give the run directory to the si command (since it supports that; see "si -help"):

ipcBeginProcess("si ~/simulation -batch -command netlist > si.log")

You don't need to pass the -cdslib necessarily (since the the default would be to pick up cds.lib), but if you did it the way that Aurélien suggested, you'd need to pass -cdslib and give the full path to the cds.lib in the working directory that Virtuoso is running in.

Hi Andrew, Aurel,

Thanks. Both of the ways work well. But there is another problem. If I run 

si ~/simulation -batch -command netlist > si.log

in a terminal, the netlist process is fast and need time of ~1s to complete. But if I run it through skill ipc command, as

cid1 = ipcBeginProcess("si ~/simulation -batch -command netlist > si.log")

ipcWait(cid1)

it will take much more time, ~10s. Before the netlist process complete, it reports two times of

Waiting for ipc:518 to terminate

Waiting for ipc:518 to terminate

What's the problem? How to solve it?

Martin

Martin,

No idea - I can't think of any particularly good reason why this should take any different amount of time. Is there any clue in the si.log file?

Perhaps you could contact customer support?

Hi Andrew,

Restart virtuoso solves the problem.
