PSpice: Display and set simulator options in the schematic (Capture)

[[email protected]]

Hi.

According to...

http://www.spectrum-soft.com/down/summer2000.pdf
"Flip-flops are set to a value dictated by the value of DIGINITSTATE,
which is set from the Global Settings
menu, or by a .OPTIONS DIGINITSTATE=<value> command somewhere in the
circuit."

.... it should be possible to display and set options within
schematics. Especially for documentation I would like to do that.

But it does not work in PSpice/OrCAD 16. I have put a text string
".OPTIONS DIGINITSTATE=1" into the Capture schematic but the string is
not copied into the .sim file as (which instructs the spice
simulator)...

I also didn't really expect that entering simulator options as text
strings would work. And the PDF above is about Micro-Cap 6...

Does anyone know a solution for PSpice/Capture to set (and display)
simulator option within the schematics?

Thanks for your response, Jim. But it does not work. I just have tried
a PARAM part with ".OPTIONS DIGINITSTATE=1". The result is:

--------------- Simulation Profile: SCHEMATIC1-bias ---------------
Simulation running...
** Profile: "SCHEMATIC1-bias" [ D:\Arbeit\Projekte\HRWS_DBFU
\PSpice_EGSE\egse-pspicefiles\schematic1\bias.sim ]
Reading and checking circuit
Invailid Param name - .options
ERROR -- Invailid Param name - .options
Run aborted
Circuit has errors ... run aborted
See output file for details
Simulation aborted


Then I have tried a PARAM part with "DIGINITSTATE=1". It does
nothing. :-(

It leads to the string ".PARAM diginitstate=1" (instead of ".OPTIONS
DIGINITSTATE=1") in the .out file and does not affect the simulation.
As far as I know the PARAM part is only used to define variables
(voltages, frequencies, ...).

Don't know about Capture, but in PSpice Schematics you _could_ simply
make a options PART and make its template as you describe. I have my
own PARAM part that handles a large list. Also "MyLib" allows a check
mark to turn library calls on and off.

Charlie E can tell us if this works in Capture.

You could also put that text line inside a file that's called by
.INCLUDE

Hi Jim,
Both work in Capture. IIRC, there is also an option file that you can
put things in, to set up 'wild and crazy' options for the simulator.

the DIGINITSTATE is what is set in the options (1,0,X) so you don't
usually have to put that in as an include file. IIRC, you can set up
each FF with an IC value as well.
