Arpad,
The current working directory is set by the EDA tool when running the AMI
simulation, and can be changed by the simulator dynamically. The current
working directory is often the location of the "Simulation Deck" but does
not have to be. The EDA tool also knows the location of the DLL, but there
is no OS call that the DLL can invoke to determine its location. So if the
EDA tool knows what the current working directory is when the DLL is
called, then the DLL_Path can be a relative path to the current working
directory when the DLL is called. If the EDA tool does not know this then
it should set the DLL_Path to be the absolute path name.

Walter,
I would like to resume the discussion on BIRD 121 in the ATM
teleconference, and if no one else makes a motion to un-table
it, I will make that motion. Hopefully we will get a second
motion and no opposition to continue the discussions on it.
I would like to ask a question on "DLL_Path", under which I
see this sentence:
"The value of DLL_Path passed to the DLL can either be an absolute path,
or a path relative to the current working directory of the simulation."
I wonder if we should define what "current working directory of
a simulation" means. Is it the directory where the simulation
project's top level netlist (or the EDA tool's schematic drawing
file) is located in, or is this the directory where the AMI DLL
is located in when it is executed, or is it a directory that the
EDA tool can set to any arbitrary directory that exists on the
machine? Does the AMI DLL have a reliable way to find out what
the current working directory is on any of the operating systems
AMI models might be written for if this parameter contains a
relative path to that location?
Thanks,
Arpad
