Uses backward Euler integration (
maxord=1 option), which can be very slow.
Set maximum iteration counts: DC iteration count limit (
itl1, default: 100), DC transfer curve iteration count limit (
itl2, default: 50), and transient analysis time point iteration count limit (
itl4, default: 10) [ltwiki]_.
I initially had some problems installing on my laptop, so decided to boot Ubuntu 12.04.5 LTS, 3.13.0-32-generic from USB and work from there.
For an automated installation script, see gpib_install.sh (and gpib.conf) below. The rest of this document describes the actions of the installation script step-by-step.
First, get the packages that are necessary to support Python bindings:
