Re: Batch Mode in Spectre

Hi,

1. The Interactive option allows faster response to simulator requests
but also locks a simulator license when in use.
When you run multiple simulations (ex corner Analysis) in batch mode,
a new start-up is required for each single simulations. Means a new
spectre process is called, License checked in, run, exit, license
checked out and so on. This behaviour slows down the simulation. This
is done only once with Interactive mode. When Spectre is launched in
Interactive mode from ADE, the license is hold until ADE gets closed.
Interactive mode is better if you're concerned about speed. You have
to use Batch if you need to free the Spectre license.
FYI: There is a more complete answer about this topic on the Cadence's
Sourcelink : SR1838156.


2. The following document shall help you:
Virtuoso® Analog Design Environment User Guide ($CDSHOME/doc/
anasimhelp/anasimhelp.pdf).
This is the bit that answers your question:

controlMode
Used to run Spectre in batch or interactive modes depending on the
value of the variable.
To set this variable in the .cdsinit file or CIW, use the call:
envSetVal(“spectre.envOpts” “controlMode” ‘string “batch”)

Hope it helps !
